To steer your Yaesu radio via the Radio 2 COM port you will use? a USB-to-Serial converter + a Yaesu CAT cable, e.g. the CT-62. This cable comes with a DB-9 connector on one side? that connects to the converter and a mini DIN plug on the other side, that connects to the radio.? So, you don't have direct access to the lines Ground and DTR. What you could do: Solder a short cable with a female DB-9 connector on one side and a male one on the other side. Connect the female side to the USB-to-Serial converter and the male side to the DB-9 connetotr of the CT-62.

Yes, that was going to be the general plan. I am looking through my junk box to see what parts I have and if I have the needed hardware.

The AMSAT Field Day 2019 event is open to all Amateur Radio opera- tors. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur satellites, both analog and digital. The congestion on FM LEO satellites is always so intense that we must continue to limit their use to one-QSO-per-FM-satellite. This includes the International Space Station.

This cubesat will be propelled solely by sunlight, to Earth orbit. LightSail 2 is scheduled to launch aboard a SpaceX Falcon Heavy on June 22, 2019, and we will attempt the first, controlled solar sail flight in Earth orbit. LightSail 2 will ride to space aboard the Department of Defense Space Test Program-2 (STP-2) mission which will send 24 spacecraft to 3 different orbits. LightSail 2 itself will be enclosed within Prox-1, a Georgia Tech-designed spacecraft originally built to demon- strate close-encounter operations with other spacecraft. Prox-1 will deploy LightSail 2 seven days after launch. After a few days of health and status checks, LightSail 2's four dual-sided solar panels will swing open. Roughly a day later, four metallic booms will unfurl four triangular Mylar sails from storage. The sails, which have a combined area of 32 square meters [344 square feet], will turn towards the sun for half of each orbit, giving the spacecraft a tiny push no stronger than the weight of a paperclip. For about a month after sail deployment, this continual thrust should raise LightSail 2's orbit by a measurable amount. LightSail 2 will fly in a 24-degree inclination, 720 km, circular orbit. At latitudes of 42 degrees north it will reach a maximum elevation of 10 degrees above the horizon. Lightsail-2 has been issued an experimental radio license WM9XPA and transmit on 437.025 MHz. A morse beacon will transmit the callsign every 45 seconds. A packet beacon will transmit AX.25, FSK 9K6 bps data.

The planned mission objectives for the 5x5x5cm 250gram satellite are: + General development of miniaturized and inexpensive satellite ? systems for space applications using off the shelf components. + Testing a new solar panel mechanism, making this satellite the ? smallest to have deployable solar arrays. These solar arrays will ? additionally increase the radar reflectivity significantly to ? that of a standard cubesat. + The promotion & involvement of students in aerospace development ? on an international level, giving them the opportunity to test ? their hardware and software experiments on the satellite. AMSAT-EA ? will be hosting STEM workshops & competitions for secondary stu- ? dents to participate in, a full section of the satellite is dedi- ? cated to these experiments for educational research. + The main mission of the satellite is the testing of a new experi- ? mental RF chirp modulation called LoRa, this new modulation hugely ? increases the link budget, reduces the power consumed and reduces ? the cost of receivers. Students & Amateurs will be able to receive telemetry from the satel- lite with inexpensive hardware, expanding & promoting the amateur satellite community among youth. Uplink challenges will also be carried out with rewards for amateurs. AMSAT-EA will provide decoding software for SDR use in order to allow anyone to decode LoRa using common existing hardware & host software for users to submit telemetry data, making all data public and reward- ing users with certificates & awards.

The rover is scheduled to launch as early as July 2020, with the spacecraft expected to touch down on Mars in February 2021. The opportunity to send your name to Mars comes with a souvenir board- ing pass and "frequent flyer" points. From now until Sept. 30, you can add your name to the list and obtain a souvenir boarding pass to Mars here: https://go.nasa.gov/Mars2020Pass The Microdevices Laboratory at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, will use an electron beam to etch the submit- ted names onto a silicon chip with lines of text smaller than one- thousandth the width of a human hair (75 nanometers). At that size, more than a million names can be inscribed on a single dime-size microchip. The chip (or chips) will ride on the rover under a glass cover.

(http://tinyurl.com/ANS-153-NZ-Maritime-Radio) The New Zealand network consists of a chain of VHF base stations, an HF Transmitter site and an HF Receiving site. These are all linked back to an Operations Centre in Lower Hutt (near Wellington). During commissioning, Terry was visiting the Operations Centre where the operators mentioned that the HF receivers were very noisy. This didn't sound right since the receiving site had been chosen because it was in a remote area well away from any man made noise. Terry said, "To check how well the receivers were working I gave the operators the frequency and a week of pass times for RS-10. This was on a Friday. On Saturday I turned on my receiver at home on RS-10. My receiver was a TenTec Argonaut 505 with DGFet preamp and a half wave dipole at about 10 feet. RS-10's downlink boomed in at about 5x7. The Maritime operators heard nothing on their receivers. I fed the audio down the phone line to convince them it was working." The four HF receivers are fed from a Multicoupler that has a "Low Noise" amplifier feeding a splitter. On the following Monday, the technicians from the maintenance base visited the site and at AOS of RS-10, turned off the power supply to the multicoupler. The Oper- ations Centre reported down went the HF noise and up came the signal from RS-10. Terry reported on the solution, "There were many options for the 'Low Noise' amplifier in the multicoupler ranging from a 2dB noise figure 10 dB gain version up to a 30dB gain 15dB noise figure version. Upon removing the lid from the multicoupler it revealed that the 30dB gain 15dB noise figure version had been supplied rather than the 2dB noise figure 10dB gainversion specified. It turned out that the manufacturers of the Multicoupler hadn't actually made one with a 2dB NF/10dB Gain amp before and had just supplied their standard version. Putting in the right amplifier solved the problem." In closing, Terry wrote, "Satellite operators who have worked with preamps will recognise this problem."

One excellent place to start is: https://uhf-satcom.com/satellite-reception/s-band ... and as for specific objects and frequencies that I have personally received, there are very strong signals from the following: 2232245000 - Tiangong-2 2245680000 - numerous CartoSat satellites 2242500000 - numerous known & unknown satellites, a popular TT&C downlink ... TLEs for the first two are available and the signals are extremely strong. Activity on 2242.5 is hit & miss - some sats don't transmit on S-Band 24x7, so it's just a frequency that you can monitor for random activity if nothing else is around.

I know the xmit/receive frequencies aren't shifted, stay the same at the satellite.

Here is where I get lost: Why do I* lower* the frequency on 435 Mhz when receiving a satellite, but *raise* the 435 Mhz frequency when transmitting to a satelllite?

When you're transmitting to AO-91 as it approaches you, you need to compensate for the fact that your RF waves are going to be compressed and appear at the satellite at a higher frequency than you are transmitting at. So you have to transmit lower than the nominal frequency. 73, Paul, N8HM On Wed, Jun 5, 2019 at 1:45 PM Philip Jenkins via AMSAT-BB wrote: > > This came up at AMSAT Academy at Hamvention, and I still can't wrap my head > around it (something simple I'm not getting, I'm sure).

AO-91 and AO-92 are UHF uplink and VHF downlink (U/v) satellites. While there is some doppler effect on VHF, the amount is minimal (2-3 KHz).? We can pretty much ignore that, with the exception of AO-92, which can require you to make an adjustment near the end of the pass. (You will notice your received audio getting scratch. So, let's focus on UHF doppler effect, which can change as much as +/- 10 KHz during a pass - Remember the train example.? The sound of a train at a distance and approaching will sound higher pitched, continually decreasing in pitch until it arrives (on frequency) at your location (closest), and continues decreasing in pitch as it passes and pulls a way from you. - On SO-50, you have to adjust your UHF rx frequency to the higher pitched frequency at the start of the pass (AOS), on frequency at mid-pass (TCA), and lower pitched frequency at end of the pass (LOS).? Thus, you will need to be 10 KHz higher at AOS, 5 Khz half way between AOS and TCA, on frequency at TCA, -5 KHz halfway between TCA and LOS, and -10 Khz at LOS.? Just remember you are adjusting your RX frequency to compensate for the effects of Doppler - On AO-91 and AO-92, it is the opposite.? You adjust your UHF uplink frequency so the satellite hears your signal at the designed uplink frequency. At AOS, doppler effect will cause your signal to sound higher to the satellite, so you need to start at a lower pitched frequency (-10 KHz), Halfway between AOS and TCA, you adjust to -5 KHz, and so on, and so on.?? I hope this helps.? If not, don't hesitate to ask. 73, Robert Bankston, KE4ALAMSAT-NA VP of User Services Twitter:? @KE4ALabamaWebsite:?

So the downward tuning of the received signal continues. It started above "actual" at the start of the pass, was dead-on right as the satellite got to its closest point, and then continued below actual as it trails off to the setting horizon. And everything is swapped for your uplink. You start out below center at the start of the pass, even with it in the middle, and above towards the end of the pass. FM satellites (such as SO-50) benefit from the "FM Capture Effect", where a strong enough FM signal can be a little off frequency and still get received correctly. This can let you not have to mess with the 2 meter band (whether up or down link), and just focus on the 70cm part. Tuning both is best, if you can, as it gets you a bit more margin.

Doppler shift is like a percentage, so the amount of, say 5%, is a bigger number for UHF compared to VHF. ? Here is the kicker, due to the way FM receiver works, it is tolerant even if the signal is a little off-frequency.? Since the doppler shift at VHF is quite small, we rarely have to adjust the FM on VHF.? However the doppler shift at UHF is beyond the tolerance of a FM receiver, so we have to frequently adjust UHF for doppler. ? 73! Umesh k6vug ? ?

From erich.eichmann at t-online.de Wed Jun 5 21:44:56 2019 From: erich.eichmann at t-online.de (Erich Eichmann) Date: Wed, 5 Jun 2019 23:44:56 +0200 Subject: [amsat-bb] Help with SatPC32 and Dual Radios In-Reply-To: References: Message-ID: <1b82b227-a137-7154-9b21-f313244318e2@t-online.de> Michael, you want to use one radio for RX and TX on VHF, the other one for RX and TX on UHF. So, I suppose you have the VFH antenna connected to one radio and the UHF antenna to the other. You are right, normally Radio 1 is always the receiver and Radio 2 the transmitter. So, if you switch between V/U and U/V sats it would be necessary to switch the antennas, e.g. using a transfer coax switch. To avoid this disadvantage check option "Autom. Rx/Tx Change" in menu "Radio Setup". (Leave all other options in the menu unchecked). This feature will change the roles of the radios as Rx and Tx. If -e.g.- radio A is the Radio 1 and connected to the UHF antenna it will be the RX with V/U sats (Fo-29). You can tune the radio around the passband and radio B will follow. If you switch to a U/V sat (AO-07) radio B will become work as the RX. You can tune it in the passband and radio A will follow. This feature works only if you switch between v/u and u/v sats, not for other bands like your 2.4 GHz downlink. Then you will? use the radio with the downconverter for RX. If the uplink 2 m user the othe for TX, if the uplink is UHF use the same FT-847. 73s, Erich, DK1TB Am 05.06.2019 um 22:32 schrieb Michael Wolthuis via AMSAT-BB: > Ok, so I am fairly new to SatPC32 since leaving my old setups.... > > I have dual FT-847's setup as follows: > > FT-847 - TX/RX UHF, RX 2.4ghz (down convert to VHF) > FT-847 - TX/RX 2m > > So, I setup SatPC32 for two radios.

If you've got waves, I'm pretty sure you're going to have a Doppler effect. Maybe aviation doesn't show much Doppler because they are going relatively slowly (compared to spacecraft) and they operate in the VHF realm, where Doppler is less obvious (like 2m on the satellites).

DATE June 6, 2019 To All RADIO AMATEURS BID: $ANS-157.01 AMSAT President Awarded Russian E.T. Krenkel Medal AMSAT President and ARRL Life Member Joe Spier, K6WAO, has been awarded the Russian E.T. Krenkel Medal, a prestigious award granted to individuals and organizations for outstanding global contributions to Amateur Radio. Joe Spier, K6WAO is a long time supporter of Amateur Radio in Space and international cooperation. K6WAO is the President of the Radio Amateur Satellite Corporation (AMSAT). He has also served AMSAT as Executive Vice President, and Vice President, Educational Relations. He is a long term supporter of Amateur Radio on the International Space Station (ARISS) and scientific, technical, engineering, and mathematics education. Spier is an AMSAT Life Member. He also is a Life Member of American Radio Relay League (ARRL) and the Society of Amateur Radio Astronomers (SARA). The award's namesake, Ernst Teodorovich Krenkel, was a radio amateur who, over the years, used the call signs RAEM, U3AA, and UA3AA. Born in Poland, Krenkel was an Arctic explorer who took part in the first Soviet "drifting station," North Pole-1. He was made a "Hero of the Soviet Union" in 1938 for his exploits. Krenkel's son, T.E. Krenkel, is among the four signatories to the award certificate. The younger Krenkel, a professor at the Moscow Technical College of Telecommunication and Informatics, said his father was an avid radio amateur who served as the first chairman of the Central Radio Club in the USSR. Krenkel's image appears on postage stamps from the USSR and Russia, and he authored a biography entitled My Callsign is RAEM. In the era when all radio amateurs received QSL cards via Box 88, Moscow, Krenkel was allowed to have his own postal address on his QSLs and was issued the non-standard RAEM call sign. Information about the Krenkel Medal can be found at: http://krenkelmedal.org/index.php?id=49 [ANS thanks the Russian National Academy of Researches and ?Discoveries for the above information] /EX In addition to regular membership, AMSAT offers membership in the President's Club. Members of the President's Club, as sustaining donors to AMSAT Project Funds, will be eligible to receive addi- tional benefits. Application forms are available from the AMSAT Office.

How to remember which way to compensate for doppler: Always adjust the higher frequency. For V/u or U/v sats, this means adjust the 70cm side and leave the 2m side fixed. Which way to move it? Very easy to remember. If 70cm is the UPlink, you'll adjust your transmit frequency UPward through the pass. If 70cm is the DOWNlink, you'll adjust your receive frequency DOWNward through the pass. I think others have basically explained why.

On linear transponder satellites (https://www.amsat.org/two-way-satellites/), you _can_ hear other stations doubling. AM is wasteful of power, as others have commented, and has no place on a power-limited satellite. The carrier, containing no information, consumes 2/3rds of the transmitted power. The rest of the power is split between two sidebands carrying the exact same information. (https://www.tutorialspoint.com/analog_communication/analog_communication_amplitude_modulation.htm) I disagree strongly with your assertion that FM was "nearly impossible" to generate.

It's just that lower frequencies do not change as much for a given satellite speed (see JoAnne's Doppler equation to determine why :-).

The event is scheduled to begin at approximately 13:05 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between OR4ISS and OK2KWX. The contact should be audible over the Czech Republic and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. D?m d?t? a ml?deze Olomouc (eng.: House of Children and Youth, abbr. DDM Olomouc) - a leisure time center which operates in 5 buildings, whereas four are situated in Olomouc. Since April 2001 the DDM is constituted by Olomouc Regional Authority. For the whole public DDM offered both regular clubs and interest groups as well as occasional and stay events. Over 150 interest groups started to work every year, regularly - once, twice or three times a week - attended by 2602 children and youth at the age from 3 to 25 years only during the last school year (2017/2018). These activities were provided by 150 employees, external and voluntary workers. During the summer holidays, DDM Olomouc organized more than 30 summer camps for almost 800 children. In summer furthermore, as during the whole year, DDM Olomouc offers cheap accommodation both right in Olomouc and in Ochoz u Konice both locations are up to 30 km away from Olomouc. Participants will ask as many of the following questions as time allows: 1. How many solar panels are powering the entire station and do you have any other power sources? 2. What voltage do your instruments using aboard the ISS? 3. What would you tell the people who believe that the Earth is flat? 4. How often do you check the social networks and have you any time to watch Youtube? 5. Did the ASTROBEE's already arrive and do you use them already? 6. How far from the station can you go and can you move outside untethered? 7. How long does it take to get from Earth to the ISS? 8. What does being in a spacesuit feel like and what is outside temperature? 9. How long do the spacesuit's energy and oxygen supplies last? 10. Do you feel any changes to your muscular system during your mission, or is it a bit of a shock after your return back to Earth? 11. Do you need to strap in when you sleep and how do you enjoy sleeping in zero gravity? 12. How often do you eat and do you enjoy the taste of the food? 13. Have you experienced any accidents while on the station, for example, a device failure? 14. How do you fight a fire if it breaks out onboard the ISS? 15. How much waste is generated on the ISS and what are you doing with it? 16. Can you play any computer games and how much free time do you have? 17. What does it feel like to fly a rocket up into space? 18. How much time do you spend exercising each day? 19. How would you deal with a serious injury, for example, hand fracture? 20. How and how often do you communicate with your family? PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Visit ARISS on Facebook.

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

I finally saw a post by one of the developers of either the N1MM Contest Logging program or the WSJT-X digital program - can't remember which - saying that if you use their program with the IC-9700 then turn OFF the CI-V Transceive function or you will have data collisions. I turned it off in my IC-9700 and haven't had the problem since (the default is ON). Go to page 8-13 in the manual to see how to get to this setting. I'd be interested in knowing how many people had this problem. ED, K0NW Original Message From: Frank Karnauskas To: Cc: Bcc: Date: Wed, 5 Jun 2019 23:41:55 -0500 Subject: [amsat-bb] SatPC32/IC-9700 Start Up Issue After watching Daniel, W5EKG's You Tube video, I had SatPC32 and the IC-9700 working beautifully on the first try. (Thanks, Daniel!) The radio frequency tracked the software real-time just like it should. However, after playing around for a few minutes (changing satellites, turning the main tuning knob, etc.) The radio suddenly stopped following the frequency changes from SatPC32. The frequency intermittently updates after 10-20 seconds accompanied by the frequency on the radio display flashing white from MAIN to SUB for a brief moment. Usually nothing happens until I choose another satellite then the frequency updates once then...crickets.

Having a fast efficient polyphase filterbank for our payload is just as important as getting an LDPC decoder for the ground! Here's a video update on this week's work in the lab: https://youtu.be/iR6CJCCg_mw The hardest parts are coming together! Still plenty to do, but these blocks have been two years in progress.

Check it out. I did have a few exceptions to the advice given, as I believe they suggest less-than-ideal operating practices. Rather than contact Sean directly, I figured it would be worthwhile to post them here. If they're controversial, perhaps it will stimulate some thoughtful discussion. I want to start off by saying that I applaud Sean for providing some very thoughtful contributions to help introduce potential new satellite ops to the birds. My intent is really to provide constructive suggestions for improvement of the advice that we as a community provide to new satellite operators to set them off on the right path.? "Currently, all FM satellites in orbit require a CTCSS (PL) tone of 67.0 Hz on your transmit frequency." Mostly true, but LilacSat-2 and PO-101 don't follow this model.? "These instructions assume you are using a hand-held directional antenna. If you?re using your standard dual-band vertical antenna at home or on the roof of your car, you can ignore those instructions."? Oh, man, I really don't think we should be encouraging newbies to try to work satellites using a vertical to receive the downlink. Also, very unsure why vertical antenna ops should ignore any of the rest of the instructions...??Maybe okay to use a vertical to transmit, but to receive they really ought to be using an antenna with gain or with the ability to rotate to match polarization, ideally both. Please, let's not encourage more alligators!? "A suggested frequency list of the three active FM satellites at the time of this writing (May 2019) is in Figure 1." Rather than provide yet another frequency list, can't we just reference an authoritative source elsewhere, e.g., on the AMSAT-NA web site? We all remember that recent ARRL article that posted many wrong frequencies; let's try to avoid risking a relapse of that. A frequency list like this can be helpful, so perhaps AMSAT-NA could include a list like this on the Frequency Summary page??FM Satellite Frequency Summary ? AMSAT | | | | FM Satellite Frequency Summary ? AMSAT | | | "Listen for a QSO to end, then give your callsign and your grid square, using standard phonetics." I don't think we should be suggesting that ops drop their call and grid on a busy FM pass. Unless you've already worked everyone else on the pass, there's really no good reason to just drop your call and grid. Find someone who is solid into the bird and appears to be hearing other stations well, and call them directly. (But not immediately after they've called someone else!) If you've already heard a callsign a couple of times during the pass, it'll also be easier to repeat it on the first try. When you wait until someone calls you, you run the risk of not being able to catch their full call on the first try and needing a fill. I think having the new op initiate the QSO gives them the best chance of having a successful first QSO.? "KX9X: ?Whiskey One Alpha Whiskey, thanks, Echo November Five Zero, Illinois, QSL??W1AW: ?QSL, Fox November Three One, Connecticut, QSL??" Much of this back-and-forth is extraneous. KX9X already provided his grid in his first transmission, and?W1AW already provided his grid in his first transmission. Neither asked for a fill. Unless a fill is needed, KX9X would normally just end the QSO with his second transmission (KX9X:? "W1AW QSL KX9X") which is really the norm. The other commonly heard pattern is when a rover is working from a rare grid. If KX9X is the rover, that first KX9X line in the sample QSO doesn't happen; the rover often announces their grid when responding to a caller, and the rover's transmission is often followed by that of a new caller calling the rover. If we want new ops to recognize when QSOs have ended, it's good for them to know how 95+% of successful QSOs really go down so they can more quickly recognize the pattern. Also, there's generally no need to identify state, unless it's a rare one. CT may be one of the few worth mentioning, but most states are not.? "With one hand holding your radio and the other holding your antenna, how are you going to log your QSOs?" Recording the pass isn't the only way to handle this, and may not even be the best approach for newbies, at least as a primary method. I've posted in the past about the benefits of operating with one's writing hand free, and logging by hand during the pass when receiving, transcribing calls and grids as I hear them. It would be a useful technique to suggest to new ops, particularly those who may not already be experienced phone contesters, as an alternative that might also help to improve their ability to work the pass. Reading a callsign you've already written down can be much easier than recalling one you only heard verbally. I cannot overstate how immensely this practice helped me.? "If you are using two HTs, you will need a diplexer, which isolates your transmitted signal from your receive radio. Without it, you will likely overload the front end of your receive radio, which will make contacts impossible. Several manufacturers such as Comet and MFJ offer diplexers; the Arrow antenna has an optional diplexer that is stored in the antenna handle." I haven't needed any filtering when using two HTs and an Arrow to work AO-91 or AO-92. Also, the BLP-200+ filter may be a useful option to suggest in lieu of those larger diplexers if one is using an Arrow antenna.? 73, Ryan AI6DO From k6vug at sbcglobal.net Sun Jun 9 04:13:22 2019 From: k6vug at sbcglobal.net (k6vug at sbcglobal.net) Date: Sun, 9 Jun 2019 04:13:22 +0000 (UTC) Subject: [amsat-bb] Satellite Basics (Part 2) article by KX9X In-Reply-To: <768585422.233703.1560039698957@mail.yahoo.com> References: <768585422.233703.1560039698957.ref@mail.yahoo.com> <768585422.233703.1560039698957@mail.yahoo.com> Message-ID: <384481943.322393.1560053602790@mail.yahoo.com> Just one thing - while it is a very good idea to refer to a known good frequency list, I have yet to come across such a list on AMSAT.ORG.?

DATE YYY To All RADIO AMATEURS BID: $ANS-160.01 AMSAT Field Day on the Satellites Most hams know about the ARRL Field Day event each June, and most who have participated in an ARRL Field Day in recent years are aware that a satellite contact will gain 100 bonus points for a participating station. However, all may not be aware that there is a parallel event sponsored by AMSAT that is geared exclusively to satellite operation. The AMSAT Field Day 2019 event is open to all Amateur Radio operators. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur sat- ellites, both analog and digital. Note that no points will be credited for any contacts beyond the ONE allowed via each single-channel FM satellite. Operators are encouraged not to make any extra contacts via theses satellites (Ex: SO-50). CW contacts and digital contacts are worth three points. Satellite digipeat QSO?s and APRS short-message contacts are worth three points each, but must be complete verified two-way exchanges. The one contact per FM satellite is not applied to digital transponders. The use of terrestrial gateway stations or internet gateways (i.e. EchoLink, IRLP, etc.) to uplink/downlink is not allowed. Complete rules and scoring details may be found at: https://www.amsat.org/field-day/ Certificates will be awarded for the first-place emergency power/port- able station at the AMSAT General Meeting and Space Symposium in the fall of 2019. Certificates will also be awarded to the second and third place portable/emergency operation in addition to the first- place home station running on emergency power. A station submitting high, award-winning scores will be requested to send in dupe sheets for analog contacts and message listings for digital downloads. You may have multiple rig difficulties, antenna failures, computer glitches, generator disasters, tropical storms, and there may even be satellite problems, but the goal is to test your ability to operate in an emergency situation. Try different gear. Demonstrate satellite operations to hams that don?t even know the HAMSATS exist. Test your equipment. Avoid making more than ONE contact via the FM-only voice HAMSATS or the ISS, and enjoy the event!

Krenkel Medal AMSAT President and ARRL Life Member Joe Spier, K6WAO, has been awarded the Russian E.T. Krenkel Medal, a prestigious award granted to individuals and organizations for outstanding global contributions to Amateur Radio. Joe Spier, K6WAO is a long time supporter of Amateur Radio in Space and international cooperation. K6WAO is the President of the Radio Amateur Satellite Corporation (AMSAT). He has also served AMSAT as Executive Vice President, and Vice President, Educational Relations. He is a long term supporter of Amateur Radio on the International Space Station (ARISS) and scientific, technical, engineering, and mathematics education. Spier is an AMSAT Life Member. He also is a Life Member of American Radio Relay League (ARRL) and the Society of Amateur Radio Astronomers (SARA). The award's namesake, Ernst Teodorovich Krenkel, was a radio amateur who, over the years, used the call signs RAEM, U3AA, and UA3AA. Born in Poland, Krenkel was an Arctic explorer who took part in the first Soviet "drifting station," North Pole-1. He was made a "Hero of the Soviet Union" in 1938 for his exploits. Krenkel's son, T.E. Krenkel, is among the four signatories to the award certificate. The younger Krenkel, a professor at the Moscow Technical College of Telecommunication and Informatics, said his father was an avid radio amateur who served as the first chairman of the Central Radio Club in the USSR. Krenkel's image appears on postage stamps from the USSR and Russia, and he authored a biography entitled My Callsign is RAEM. In the era when all radio amateurs received QSL cards via Box 88, Moscow, Krenkel was allowed to have his own postal address on his QSLs and was issued the non-standard RAEM call sign. Information about the Krenkel Medal can be found at: http://krenkelmedal.org/index.php?id=49 [ANS thanks the Russian National Academy of Researches and Discoveries for the above information] --------------------------------------------------------------------- AO-85 Back in Operation AO-85 is almost back in full sun.

This definitive reference is written for the new satellite operator by Gould Smith, WA4SXM, but includes discussions for the experienced op- erator who wishes to review the features of amateur satellite communi- cations.

CAS-7B ( BP-1B ) is scheduled to be launched at the end of June this year, according to a June 1 news release that has been widely disseminated. Because of the orbital apogee and the size and mass of the satellite, the orbital life of the satellite is expected to be only one week, up to a maximum of one month, which will also provide with an opportunity for hams to track and monitor satellite entering the atmosphere. The launch will use a new launch vehicle from a small commercial rocket company. This is the first launch of this launch vehicle, and there is a large possibility of failure. However, if successful, the satellite will send CW telemetry on 435.715 MHz. There will also be an FM crossband repeater with uplink at 145.900 MHz and downlink at 435.715 MHz.

DATE YYY To All RADIO AMATEURS BID: $ANS-160.01 AMSAT Field Day on the Satellites Most hams know about the ARRL Field Day event each June, and most who have participated in an ARRL Field Day in recent years are aware that a satellite contact will gain 100 bonus points for a participating station. However, all may not be aware that there is a parallel event sponsored by AMSAT that is geared exclusively to satellite operation. The AMSAT Field Day 2019 event is open to all Amateur Radio operators. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur sat- ellites, both analog and digital. Note that no points will be credited for any contacts beyond the ONE allowed via each single-channel FM satellite. Operators are encouraged not to make any extra contacts via theses satellites (Ex: SO-50). CW contacts and digital contacts are worth three points. Satellite digipeat QSO?s and APRS short-message contacts are worth three points each, but must be complete verified two-way exchanges. The one contact per FM satellite is not applied to digital transponders. The use of terrestrial gateway stations or internet gateways (i.e. EchoLink, IRLP, etc.) to uplink/downlink is not allowed. Complete rules and scoring details may be found at: https://www.amsat.org/field-day/ Certificates will be awarded for the first-place emergency power/port- able station at the AMSAT General Meeting and Space Symposium in the fall of 2019. Certificates will also be awarded to the second and third place portable/emergency operation in addition to the first- place home station running on emergency power. A station submitting high, award-winning scores will be requested to send in dupe sheets for analog contacts and message listings for digital downloads. You may have multiple rig difficulties, antenna failures, computer glitches, generator disasters, tropical storms, and there may even be satellite problems, but the goal is to test your ability to operate in an emergency situation. Try different gear. Demonstrate satellite operations to hams that don?t even know the HAMSATS exist. Test your equipment. Avoid making more than ONE contact via the FM-only voice HAMSATS or the ISS, and enjoy the event!

Krenkel Medal AMSAT President and ARRL Life Member Joe Spier, K6WAO, has been awarded the Russian E.T. Krenkel Medal, a prestigious award granted to individuals and organizations for outstanding global contributions to Amateur Radio. Joe Spier, K6WAO is a long time supporter of Amateur Radio in Space and international cooperation. K6WAO is the President of the Radio Amateur Satellite Corporation (AMSAT). He has also served AMSAT as Executive Vice President, and Vice President, Educational Relations. He is a long term supporter of Amateur Radio on the International Space Station (ARISS) and scientific, technical, engineering, and mathematics education. Spier is an AMSAT Life Member. He also is a Life Member of American Radio Relay League (ARRL) and the Society of Amateur Radio Astronomers (SARA). The award's namesake, Ernst Teodorovich Krenkel, was a radio amateur who, over the years, used the call signs RAEM, U3AA, and UA3AA. Born in Poland, Krenkel was an Arctic explorer who took part in the first Soviet "drifting station," North Pole-1. He was made a "Hero of the Soviet Union" in 1938 for his exploits. Krenkel's son, T.E. Krenkel, is among the four signatories to the award certificate. The younger Krenkel, a professor at the Moscow Technical College of Telecommunication and Informatics, said his father was an avid radio amateur who served as the first chairman of the Central Radio Club in the USSR. Krenkel's image appears on postage stamps from the USSR and Russia, and he authored a biography entitled My Callsign is RAEM. In the era when all radio amateurs received QSL cards via Box 88, Moscow, Krenkel was allowed to have his own postal address on his QSLs and was issued the non-standard RAEM call sign. Information about the Krenkel Medal can be found at: http://krenkelmedal.org/index.php?id=49 [ANS thanks the Russian National Academy of Researches and Discoveries for the above information] --------------------------------------------------------------------- AO-85 Back in Operation AO-85 is almost back in full sun.

I had gotten the mistaken impression that SatPC32 always updated the frequency in the radio on a regular basis, i.e., every few seconds or so. Apparently it only updates the radio "whenever it needs to." For the sake of education to other rookies such as myself...read on. When I first connected the IC-9700 to SatPC32, I tested it on a satellite pass that was in range. Yoo-Hoo! Everything worked as advertised, and on the first try! SatPC32 updated the radio frequency every few seconds. In my subsequent observations, SatPC32 updated the radio frequency once every ten-to-seconds seconds, if at all. This is when I thought I had broken something for some unknown reason. This was in the middle of night here in Minnesota and there were no visible passes for the active birds. The following morning, after an exchange of emails with Erich to verify that all my settings were correct, I immediately noticed that SatPC32 did update the radio frequency every few seconds for satellites as they became visible to my location. Aha! Lesson learned: If you are testing your connection between your radio and SatPC32, test with satellites that are in range, not with those that are on the other side of the planet. Great program, Erich...thank you for your contribution to this great hobby! 73, FRANK KARNAUSKAS, N1UW "We have no problems, only insurmountabe opportunities." - FWK -----Original Message----- From: AMSAT-BB [mailto:amsat-bb-bounces at amsat.org] On Behalf Of Edward Roth via AMSAT-BB Sent: Saturday, June 8, 2019 12:36 AM To: amsat-bb at amsat.org Subject: [amsat-bb] SATpc32/IC-9700 Start Up Issue I wrestled with this problem for over a week trying everything I could think of to change and test. I finally saw a post by one of the developers of either the N1MM Contest Logging program or the WSJT-X digital program - can't remember which - saying that if you use their program with the IC-9700 then turn OFF the CI-V Transceive function or you will have data collisions. I turned it off in my IC-9700 and haven't had the problem since (the default is ON). Go to page 8-13 in the manual to see how to get to this setting. I'd be interested in knowing how many people had this problem.

(Thanks, Daniel!) The radio frequency tracked the software real-time just like it should. However, after playing around for a few minutes (changing satellites, turning the main tuning knob, etc.) The radio suddenly stopped following the frequency changes from SatPC32. The frequency intermittently updates after 10-20 seconds accompanied by the frequency on the radio display flashing white from MAIN to SUB for a brief moment. Usually nothing happens until I choose another satellite then the frequency updates once then...crickets. _______________________________________________ Sent via AMSAT-BB at amsat.org.

I couldn't seem to get the doppler correction to work right. SatPC32 kept wanting to switch the radio back to the default DOPPLER.SQF listed frequency pairs. I had to do manual doppler correction. After Icom released the version 1.10 update this week and I updated, I tried again. Perfect rock solid doppler correction of the 9700 (once I did the calibration between uplink and downlink in SatPC32). They mention in the updates "The CI-V commands 25 and 26 work correctly". So if you have a 9700, be sure to update your firmware to the latest fix. http://www.icom.co.jp/world/support/download/firm/IC-9700/1_10/ And a thanks to Eric DK1TB for updating SatPC32 with the 9700 selection!

One "trick" I have used is to prepare the "logsheet" ahead of time by writing the satellite name, my grid, the date. etc across the top as the first line. Then write a vertical column of UTC times (just four digits for hour-hour-minute-minute) from AOS to LOS down one side of the page with plenty of space between each minute-line. Starting as AOS, at the top of the page, whenever I hear a callsign, I write down the callsign (and grid if I get that too) even if I know I've already worked this station. They might call you later in the pass and you'll have his call "ready" on the logsheet. When I have worked someone, I can quickly circle their callsign then draw a line over to the appropriate minute for the QSO and circle the time. This is usually faster (for me at least) than writing the time after working him, and the circled-callsign-line-circled-timestamp adds (for me at least) an extra confirmation that, yes, I actually worked this callsign, not just that I heard this callsign on this pass. Prepare all of the logsheets for all your passes ahead of time, put them on a clipboard and use a rubber band or clip to hold the bottom of the page to the clipboard just in case it gets windy. My other suggestion would be to get a tripod or a stand with a big clip and use that to hold your Arrow/cheap yagi/whatever antenna. With a little practice, you can adjust the antenna quickly, re-peak the signal, and you should be good for a short while before you need to touch the antenna again. This will free up the hand that would have been holding the antenna to do other tasks. 73, Douglas KA2UPW/5 On Sat, Jun 8, 2019 at 7:23 PM Ryan Noguchi via AMSAT-BB wrote: > Sean KX9X posted another introductory article on satellite operating on > https://www.onallbands.com/satellite-basics-part-2-making-qsos-via-satellite/. > Check it out. > > I did have a few exceptions to the advice given, as I believe they suggest > less-than-ideal operating practices.

I can only speak to the SDRPlay RSP1 and Airspy R2, but those are two of the SDRs available that are significantly superior to the basic RTL-SDR devices. Many people use the premium SDRs such as these products for some really weak (and/or dirty) signal reception. The SDRPlay products are particularly good for full-duplex transponder use, too. For linear satellites, I use the SDRPlay RSP1 exclusively as my receive "radio".

I log on Post-it notes in real time during the pass. Before the pass starts, I'll prefill it with known or expected rovers. When I hear calls and grids, I write them down. When I complete a QSO, I'll write a sequential number next to the call. If someone calls me who isn't already on the list, I'll write down their call (and grid, if any) while I receive.? After the pass, I'll add any pass details to the Post-it note so I can tell them apart. When I transcribe the QSOs into my Excel workbook, which creates an ADIF file for upload to LoTW, I guesstimate the QSO times based on roughly when in the pass they occurred. I'm probably no more than a minute or two off of reality, but I don't really need to be this precise, as LoTW will match times that are off by longer than the longest pass duration, but it's what I'm used to.? I sometimes record the pass--both ambient sound using my phone and the received downlink on my TH-D74--but almost never need to refer to them. I don't miss having to spend another 12 minutes listening to a 12 minute pass just to transcribe and log.? I can operate hand-free because I have my radios attached to my body in such a way that the display and controls are readily accessible. For FM birds, my Tx HT is clipped to a holster on my belt with the display facing up and the VFO knob facing to my right for easy access by my right hand, and my Rx HT is clipped to my belt.?This "holster" is a MOLLE strap magazine pouch that normally holds my phone; the HT clips nicely into the MOLLE straps above my belt.?My Tx HT has an earpiece with lapel mic. I press the PTT switch on the lapel mic to transmit, and let it go when I need to write.?When I'm working a linear portable, my FT818 is in a shoulder bag with display and control head facing me, and the Rx HT is clipped to the holster mentioned above. The FT-818 has a latching PTT switch separate from the mic that I can hold along with the pen.? This approach also allows me to operate completely pedestrian-mobile so I can move during the pass to clear obstacles and distance myself from local noise sources.? 73, Ryan AI6DO On Monday, June 10, 2019, 8:51:24 AM PDT, Douglas Quagliana wrote: Ryan writes:> I've posted in the past about the benefits of operating with one's writing hand >free, and logging by hand during the pass when receiving, transcribing calls >and grids as I hear them. One "trick" I have used is to prepare the "logsheet" ahead of time by writing the satellite name, my grid, the date. etc across the top as the first line.? Then write a vertical column of UTC times (just four digits for hour-hour-minute-minute) from AOS to LOS down one side of the page with plenty of space between each minute-line.? Starting as AOS, at the top of the page, whenever I hear a callsign, I write down the callsign (and grid if I get that too) even if I know I've alreadyworked this station. They might call you later in the pass and you'll have his call "ready" on the logsheet. When I have worked someone, I can quickly circle their callsign then draw a line over to the appropriate minute for the QSO and circle the time.? This is usually faster (for me at least) than writing the time after working him, and the circled-callsign-line-circled-timestamp adds (for me at least) an extra confirmation that, yes, I actually worked this callsign, not just that I heard this callsign on this pass. Prepare all of the logsheets for all your passes ahead of time, put them on a clipboard and use a rubber band or clip to hold the bottom of the page to the clipboard just in case it gets windy. My other suggestion would be to get a tripod or a stand with a big clip and use that to hold your Arrow/cheap yagi/whatever antenna.? With a little practice, you can adjust the antenna quickly, re-peak the signal, and you should be good for a short while before you need to touch the antenna again.? This will free up the hand that would have been holding the antenna to do othertasks. 73,Douglas KA2UPW/5 From jim at milnet.uk.net Tue Jun 11 08:29:49 2019 From: jim at milnet.uk.net (Jim Heck) Date: Tue, 11 Jun 2019 09:29:49 +0100 Subject: [amsat-bb] AO73 Mode change In-Reply-To: <13DF423C17994667998D9A42D1851FEA@jimPC2> References: <39ED40E1AB4A4BC59C531C1A3F21D575@LAPTOP91ASAKDB><9961032CCB324FD6B68EE759E695E3B9@jimPC2> <13DF423C17994667998D9A42D1851FEA@jimPC2> Message-ID: Hi Folks After evaluating the transponder now that the satellite temperatures are returning to normal, we plan to resume transponder operations from the coming weekend.

Phil- There is much information available to catch up on recent (and not so recent) advances. The author of Linrad has done some dynamic range comparisons: https://www.youtube.com/watch?v=QbSa1G14Nig Note that a receiver that is too sensitive may be easily overloaded by a strong signal, requiring an attenuator proceeding it and resulting in an increase in noise figure. A less sensitive receiver that performs better on the "top end" when strong signals are present can be helped out with a switchable LNA at the antenna. Which is, of course, where the LNA should be to set the system noise figure. No strong signals and you need some more sensitivity, switch on the LNA. https://youtu.be/_-AkINSPkhw?t=505 --- Zach N0ZGO From ai6do at yahoo.com Tue Jun 11 18:13:00 2019 From: ai6do at yahoo.com (Ryan Noguchi) Date: Tue, 11 Jun 2019 18:13:00 +0000 (UTC) Subject: [amsat-bb] NO84 in safe mode In-Reply-To: <92e5a61b-f2b6-1834-f330-b930c242ded0@gmail.com> References: <117d39d3-8935-b53f-e02d-b8cc666e85ca@mwt.net> <5caf69ef-82ba-26c0-45cd-609c0eea1357@gmail.com> <1898285815.961890.1560221050602@mail.yahoo.com> <92e5a61b-f2b6-1834-f330-b930c242ded0@gmail.com> Message-ID: <1385545789.1261793.1560276780491@mail.yahoo.com> To be fair, my experience is only with the RSP1A, which is two years (two generations!) newer than the RSP1 that Scott uses.?If you're looking to inexpensively add a receiver to a transmitting radio for a full duplex satellite system, the $120 RSP1A is a very serviceable option and much cheaper than a transceiver. I don't think the RSP1 is available new any longer.? You're right in that in certain portions of amateur radio, the equipment is evolving very quickly; in other areas, very glacially. I bought a new FT-818ND last year, which is not really a substantive improvement over the FT-817ND, which has been around for fifteen years. I use it exclusively as a transmitter for linear satellite work, and it works well in that role, as would your FT-817.? 73, Ryan AI6DO On Tuesday, June 11, 2019, 6:29:05 AM PDT, Phil via AMSAT-BB wrote: On 11/6/19 12:44 pm, Ryan Noguchi via AMSAT-BB wrote: >?

But I recently found that the OUTERnet system has changed to a new GEO satellite constellation and no longer uses INMARSAT L band satellites but is now using a KA band downlink over the USA. And that they are now selling a new receiver kit for this satellite. Has anyone kept up with them? Here is my original WEB page but with the links changed from OUTnet to OTHERnet: http://aprs.org/othernet.html If anyone has one of their receivers or is receiving the downlink and/or wants to help me get my web page all cleaned up to what has changed over the last two years, let me know. This is a powerful capability. I hope we can keep it working.

Thank you Zach and Ryan, I've recently renewed my interest in computer programming after practically no activity for the past 15 years; Amateur Radio is in the same boat. So much to catch up on and so little time left to do so. I sold my FT-817 20 years ago because I wasn't making much use of it and bought an FT-847. AO-40 really had me excited for a couple of years but after its demise I slowly lost interest and the radio hasn't seen the light of day for a long time. -- Regards, Phil From w9gb at icloud.com Tue Jun 11 22:31:38 2019 From: w9gb at icloud.com (Gregory Beat) Date: Tue, 11 Jun 2019 17:31:38 -0500 Subject: [amsat-bb] Launch weight (mass) of Phase 3-E (Express)?

The event is scheduled to begin at approximately 11:10 UTC. It is recommended that you start listening approximately 10 minutes before this time.The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and VK4KHZ. The contact should be audible over portions of Australia and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Peninsula Grammar is a day and boarding school for approximately 1400 students from three-year-old Kindergarten to Year 12. At Peninsula Grammar we see learning not just as a path to university and a career, but also as a path to wellbeing. The books we read, the science we absorb, the languages we learn, the artistic, sporting and musical skills we acquire are the tools that enable us to fulfil our potential. Participants will ask as many of the following questions as time allows: 1. Although you are in quarantine before going to space, if someone was to get sick or injured in space, is there always a qualified first aid person when it happens? 2. How long will it take to recover and will you miss the space station when you come down? 3. What is your favourite thing to do in space? 4. What was your first thought during lift off when you travelled to the space station? 5. What kind of science experiments are you doing? 6. Why did you choose to be an astronaut? 7. How do you use the Internet on board the space station? 8. When you were first selected to go to the ISS in 2013, were you thinking about how much your research might affect the future on Earth and did that help you cope with leaving your family behind, getting into a space craft with people you don't really know and possibly risking your life? 9. What training did you do to become an astronaut? 10. Have you ever had a major issue with any of the technology on board the space station? 11. What is currently being done to try to help your life in space become easier? 12. How has your understanding of the universe changed now that you have seen it from space? 13. What do you miss most about Earth? 14. Can you have baths or showers in space? 15. Did the air force help you with what you are doing in space now?

As you have found, the "plus" version of AGW_Online_Kiss does indeed generate some errors that are difficult to resolve. But that version of the utility provides more functionality than you really need just to generate .KSS files. In fact, I normally use the original non-plus AGW_Online_Kiss on Windows and have copied it over to linux for use under Wine. By placing one dependency file in the same folder where the .EXE is located, it runs very nicely. Of course, the .INI file needs to be edited for each person. Lastly, this utility simply listens on the specified AGW port for packets from your software soundmodem of choice. On linux, Direwolf is by far the best tool to use. I have included an appropriate direwolf .CONF file at the URL I'll list below. So the Direwolf command would be: direwolf -c direwolf-1200.conf ... and after that is running, start AGW_Online_Kiss.exe. Click the "Connect AGW" button and you should see confirmation of a connection to Direwolf. When packets are heard over the audio path that Direwolf is monitoring, if all the settings match (baud rate, etc.) you'll see the decodes in AGW_Online_Kiss and a .KSS file (and optionally .LOG file) will be created for you. I have placed this version of AGW_Online_Kiss, the .OCX dependency, and that sample Direwolf .CONF file at: https://www.qsl.net/k/k4kdr//downloads/agw-kss-linux/ ... please review the .INI and .CONF file to verify that they are suitable to your configuration. If you need to decode packets other than 1200 baud, I recommend copying that .CONF file to a new file and editing it appropriately. -Scott, K4KDR ============================ On Wed, Jun 12, 2019 at 10:49 AM Hans BX2ABT via AMSAT-BB < amsat-bb at amsat.org> wrote: > You have to trust me on that one: checked everything thrice.

The work has been done. #2, if memory serves, some radios do not respond to CAT frequency adjustments when transmitting. In this mode, your uplink radio is transmitting non-stop for the entire ~10 minute pass. If you have a hardware/software setup that can only change RF frequency when in receive mode, that will never happen during an NO-84 pass. Lastly, like much satellite work, the uplink and downlink are two completely separate discussions in this mode. While the 10m uplink works extremely well with the DopplerPSK software and the HF radio of your choice, receiving & demodulating the PSK31 downlink can be done by any antenna/FM radio(or SDR), and computer combination of your liking. Just as one example, my setup is: TX: Windows PC > DopplerPSK > Signalink > FT-857d > MyAntennas EFHW-8010 RX: 70cm X-Quad > SDRPlay RSP1 > HDSDR on Windows PC (doppler track w/ Orbitron) > FLDigi -Scott, K4KDR ============================== On Wed, Jun 12, 2019 at 8:20 PM k6vug at sbcglobal.net wrote: > I'm very curious about this, thanks for sharing the links. > > Looks like the program adjusts the PSK modulation within the pass band of > the uplink, and at 10 meters, that would be relatively small.

This older version does start up and I'm waiting for some telemetry to come in right now. And it does indeed connect to Direwolf, which is much better than HS_soundmodem in the sense that it doesn't use the soundcard to route audio from GQRX, but UDP instead. Great! Thanks Scott. @JE9PEL: all OCX files were registered, checked not once, not twice, but thrice. So what I suspected already is that the recent versions of AGW_onlinekiss_plus and getKiss share a similar code base, which is different from the previous AGW_onlinekiss. Now Jan, your instructions on how to install on Linux are very clear, but if they can't be reproduced by an innocent passerby then they are of little use. Have you tried it on a clean install, like Ubuntu 19.04? Final request: can someone post or email me an example .kss file from any current sat (like the XW, CAS, etc.) for me to test the decoder?

I think the Doppler rate (delta-Doppler shift) at even 10m is too fast for most radios--what you often get with CAT control, even if you can update while transmitting, is PSK31 that jumps more than 31Hz per update, and that totally destroys the phase continuity required to tell a '1' from '0'.? This was the "fun" problem that spurred me to take a swing at it over a summer vacation. When DopplerPSK applies "anti-doppler" on the transmitted signal, it does so at the baseband audio level.? This works fine for 3Khz passbands on a 10m uplink, but if you want to do it with SSB transponders and VHF and UHF you'll need an SDR where you aren't limited by an IF filter.? ?The same algorithm in DopplerPSK could be used on a complex signal in the SDR architecture, and it could work equally on TX and RX in the processing chain.? ?To the accuracy of the orbital elements everyone uses, if everyone corrects their uplink and downlink properly there is no perceived frequency drift by anyone using the satellite.? Just what you need for a GHz-range LEO with a narrow-band transponder, eh?? Since the downlink of NO-84 is FM there is no Doppler shift in the baseband audio of the downlink--you hear what the satellite hears.? If we get a mode-K satellite it might be worthwhile to do a baseband demodulator in a soundcard since the total change in Doppler shift will be small enough to fit in a conventional HF radio's IF passband in both directions. If the antiquated hosting site doesn't come back I'll get off my duff and find a "proper" place for it.? It's nice to see people playing around with it. (Thanks for bridging the gap in the meantime, Peter.)

The work has been done. #2, if memory serves, some radios do not respond to CAT frequency adjustments when transmitting.? In this mode, your uplink radio is transmitting non-stop for the entire ~10 minute pass.? If you have a hardware/software setup that can only change RF frequency when in receive mode, that will never happen during an NO-84 pass. Lastly, like much satellite work, the uplink and downlink are two completely separate discussions in this mode.? While the 10m uplink works extremely well with the DopplerPSK software and the HF radio of your choice, receiving & demodulating the PSK31 downlink can be done by any antenna/FM radio(or SDR), and computer combination of your liking.?

All FM-only rigs of course only do 5 KHz steps anyway. Are we finding that multi-mode rigs when placed in FM mode can actually step smaller under CAT control? If so, then we must point that out to users, since it will not work for PSK31 even in FM. Thanks for the reminder. If rigs do that, then I will add this to the PSAT web page. The advice to not use auto-radio tuning except for 5 KHz steps on the downlink. IE, not smaller steps.

While the 10m uplink works extremely well with the DopplerPSK software and the HF radio of your choice, receiving & demodulating the PSK31 downlink can be done by any antenna/FM radio(or SDR), and computer combination of your liking.

The audio in an FM signal shouldn't change with small changes in the receiver frequency, due to the FM capture effect. That's assuming that the act of changing the frequency, even by such a small amount, doesn't "jiggle" the phase of the decoded audio in the process. Is that the concern?

PSK31 needs phase coherence well under 31 Hz to properly decode. Better to tell your software to only step the radio once every 2.5 KHz maybe to minimize these glitches and loss of characters while still keeping the FM signal in the passband.

From tjschuessler at verizon.net Thu Jun 13 20:18:52 2019 From: tjschuessler at verizon.net (tjschuessler at verizon.net) Date: Thu, 13 Jun 2019 15:18:52 -0500 Subject: [amsat-bb] DopplerPSK - No 1 kHz-autotracking radio Message-ID: <00d501d52225$3898ccd0$a9ca6670$@verizon.net> DopplerPSK is a great program for dealing with doppler shift on the 10 meter uplink. The point being made that Yes, all mode rigs can do very small tuning steps in VFO mode as can my FT847. If I were going to use that one rig for NO-84, even with SatPC32, I would turn the doppler correction for uplink "OFF" and only track the 435 downlink FM so I could hear the FM carrier throughout, but let doppler PSK adjust audio tone for doppler and that will nicely keep the PSK signal stable AT the Satellite, inside the 28.120 + 3Khz receive passband. The cool thing is that you can still use just an FM mobile rig to receive the FM downlink, and 5Khz steps will still work pretty much just fine.

You cannot just tune the 10m uplink like you would a linear transponder with SatPc32. It will make the PSK31 signal on the transponder undecodeable. The only real way to work it is with Doppler PSK. My setup consists of a FT-847 on the 70cm downlink, with SatPC32 correcting the doppler on the downlink which by the way I have no issues with. Then I have my FT-950 doing the uplinking on 10m (I use the FT-847 for VHF/UHF/Sat Only and FT-950 for HF only). I use a homebrew dipole that is actually for 40/80m but it tunes up on 10 meters just fine and works well for the uplink on NO-84. I then use FLdigi to decode the PSK31 signals as FLDigi allows multi-decoding for PSK31 which allows me to decode multiple signals in the passband at once. And of course I use DopplerPSK for the generation and correction of the PSK31 signal. Hope this helps. Unfortunately there is not a lot of activity on the PSK31 transponder but I hope that changes with the upcoming launch with Psat-2. - Nick KE8AKW From burns at fisher.cc Thu Jun 13 21:20:09 2019 From: burns at fisher.cc (Burns Fisher) Date: Thu, 13 Jun 2019 17:20:09 -0400 Subject: [amsat-bb] AO-85 is still kicking...

With your 4.9W,that would only be about 1/2 W. Doesn't seem like much tobe worrying about. Polarization should be more of a concern. GL/73,? ? ?Bob?

Just walked in this evening (14-June-2019) & happened to catch the ISS at decent elevation around 2230 UTC. The packet digipeater sounded great and I had a quick exchange of digipeated 'Message' packets with W4TBD who happens to be just on the other side of town. As the ISS tracked NW to SE, I stood by to see who else might be around. I keep the FM radio's squelch open & volume up a little to judge how the downlink packets are sounding. All of a sudden, there was a dead carrier on (or at least near) the 145.825 ISS packet downlink. Sounded like a neighbor keying up to mess with me - except for the fact that I don't have any neighbors. I quickly spun another radio to the area of 145.825 and set it to USB to see if I could recognize what that jamming carrier was. Turns out it wasn't a dead carrier at all, but a tone sweeping back and forth. Someone else needs to check me (since you can't ever be sure from a single observation), but from the SUBJECT line of this post you know that the offending tone appeared to be from XW-2D which was passing directly overhead at the same time. Here is a link to a screen shot of their orbits when this happened: https://www.qsl.net/k/k4kdr//images/iss-xw2d.png ... so, if this VERY strong 2-meter signal was in fact from XW-2D, you might want to keep track of where that satellite is located just as a point of reference. There have been previous posts about XW-2D's transponder not working correctly. If you have uplink or downlink trouble with anything that operates in the 145.800 - 145.900 range, this might be the cause if I'm guessing correctly. 73, -Scott, K4KDR From kd6yam at amsat.org Sat Jun 15 00:37:51 2019 From: kd6yam at amsat.org (Martin Cooper) Date: Fri, 14 Jun 2019 17:37:51 -0700 Subject: [amsat-bb] More reliable source than SatNOGS DB? Message-ID: I'd been contemplating using the SatNOGS database to do automated lookups of transmitter info for satellites (from code), but frankly the database seems to be a bit of a mess. For example, in the 'satellites' database, there are cases of the same satellite name mapping to multiple NORAD catalog ids, the 'names' field being used inconsistently (and even containing an essay about the satellite in one case), and so forth. Similarly, the 'transmitters' database also has issues. Is there a more reliable source that can be queried through an API? I know N2YO has an API, but it's focused on real-time tracking, and doesn't appear to include transmitter info (though the site's satellite pages do). Thanks! Martin.

The event is scheduled to begin at approximately 18:11 UTC. It is recommended that you start listening approximately 10 minutes before this time. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and W6SRJ. The contact should be audible over the east coast of the U.S. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. National Air and Space Museum - Steven F. Udvar-Hazy Center Innovations in Flight Family Day The theme of this program is to give museum visitors the opportunity to learn about the innovations in aircraft design and what it takes to become a pilot by talking with pilots about how they learned to fly, what they fly, and how they use their aircraft. The day is designed to inform visitors of the opportunities in both military and civilian aviation. Visitors have the opportunity to talk with a diversified group of pilots to see different types of aircraft. This year we are celebrating the 50th Anniversary of the Apollo Program. Participants will ask as many of the following questions as time allows: 1. What is your favorite thing to do in microgravity? 2. How important are the people in mission control? 3. What is a normal day look like? 4. What was the launch like? 5. What is your least favorite part of being in space? 6. Are there any animals on station? 7. Did you know you wanted to be an astronaut when you were a kid? 8. There is a NASA T-38 at this event, what was your biggest challenge in learning to fly? 9. Where are you now? 10. What is your favorite space food? 11. What happens if someone gets sick? 12. What is around you? 13. Do you have a degree in science? 14. What kind of exercise do you do? 15. Do you have ice cream? 16. Do you ever get bored? 17. What did you take up with you that is special? 18. What do you miss?

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

If we all contribute to it, we can build something very useful for everyone. About duplicate satellite, this is an issue of using the norad id as id and will be solved once and for all when we move to satellite uuid. For the transmitters indeed, there is a mess right now due to having in the past new transmitter for each drift on frequency. There is currently a lot of work on the database to clean it. By the way, this is also the database that is used by Gpredict.

Each year the Ameri- can Radio Relay League (ARRL) sponsors Field Day. The Radio Amateur Satellite Corporation (AMSAT) promotes our own version of Field Day focused on operation via the amateur satellites, held concurrently with the ARRL event. The AMSAT Field Day 2019 event is open to all Amateur Radio opera- tors. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur satellites, both analog and digital. The congestion on FM LEO satellites is always so intense that we must continue to limit their use to one-QSO-per-FM-satellite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating Voice. +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ Note that no points will be credited for any contacts beyond the ONE allowed via each single-channel FM sat- ellite.

During the ARISS Forum at the Hamvention, it was announced, that between now and June 17, that an anonymous donor will equally match one dollar for each dollar donated up to $10,000. Here is an excellent opportunity to get the most from your donations to the ARISS FundRazr. The FundRazr Project was initiated to raise $150,000 towards the ARISS Radio Upgrade on ISS. To date 100 contributors have donated $26,200 to the campaign, about 17% of the goal. Please donate today at https://fundrazr.com/arissnextgen?ref=ab_6ruVeeeNzOa6ruVeeeNzOa [ANS thanks AMSAT for the above information] --------------------------------------------------------------------- AMSAT Operations Updates AO-85 Status / AO-92 Field Day Plans AO-85's FM repeater is still active during the current period of full illumination. Both downlink and uplink frequencies are off freq- uency low and DUV telemetry is not active. Continued operations are not guaranteed after the full illumination period ends on June 19. Work it while you can! AO-92 will be available in both U/v and L/v for Field Day this year. The current plan is to command AO-92 to L/v on the 0416Z pass on June 22, the evening before Field Day. The 24 hour timer will then run to expiration, and the satellite will revert to Mode U/v for the remainder of Field Day weekend. The planned timing should provide for at least one accessible pass for the continental US in L/v before returning to U/v. If commanding to L/v on the 0416Z pass is not successful, we will reattempt Field Day morning. Please keep the uplink clear during commanding. Additionally, requests were made to the LilacSat-2, IO-86 and PO-101 command stations for special scheduling of these FM repeaters for Field Day. Please watch for these teams? schedule announcements on Twitter and amsat-bb prior to Field Day weekend. Note that IO-86 is only accessible to those stations below about 30 degrees of latitude, but is a very strong repeater and easily worked to the local horizon. The FM repeaters on AO-91 and SO-50 are also expected to be available as normal during Field Day.

The following sets out the current IARU position on these proposals. A proposal from France to consider the band 144-146 MHz as a primary allocation to the Aeronautical Mobile service, as part of a broader consideration of the spectrum allocated to that service. The band 144-146 MHz is allocated globally to the amateur and amateur satellite services on a primary basis. This is one of the few primary allocations to the amateur service above 29.7 MHz and as such is an important and widely used part of the amateur spectrum with a vast installed base of users and operational satellite stations. IARU views with grave concern any proposal to include this band in the proposed study. It will be representing this view energetically in Regional Telecommunications Organisations and in ITU to seek to obtain assurances that the spectrum will remain a primary allocation for the amateur services. A proposal to study the amateur allocation in the 1240-1300 MHz ("23cm") band following reported cases of interference to the Galileo navigation system. IARU is aware of a handful of cases where interference to the Galileo E6 signal has been reported. In all cases these have been resolved by local action with the full cooperation of the amateur stations concerned. IARU does not want the amateur service to affect the operation of the Galileo system in any way. Joint studies have been carried out to assess the true vulnerability of the system and, based on these, IARU regards the proposal to initiate an Agenda item for WRC-23 as pre- mature. The IARU position is that proper technical assessment of the issues involved should be made in the relevant CEPT study group. Proper account needs to be taken of the operational characteristics of the amateur service in order to develop sensible and proportionate measures that will facilitate the continued utility of the band for amateur experimentation whilst respecting the primary status of the GNSS service. IARU is ready to cooperate fully in any studies and shares the objective of reaching a secure and permanent solution to the issues of sharing in this band. IARU asks its Member Societies to draw this information to the attention of their members, and to refrain at this time from making speculative public comments about the situation until further progress has been made in regulatory discussions. IARU is also ready to discuss this issue with other societies not in IARU membership.

Almost every pass, there is someone calling CQ over and over again with a loud signal, but completely oblivious to the several stations trying to answer them. Downlinks on the linear satellites, especially on UHF, are MUCH weaker than on the FM satellites. Remember that the transmit power of the satellite is being distributed across an entire passband that many stations are sharing -- unlike FM, where all the power is just on one frequency for one station at a time (ideally). You are going to need the best, low-loss feedline you can afford for UHF, and that feedline needs to be as short as possible. If your feedline is more than about 50 feet (or about 15 meters) you are going to want to have a pre-amplifier very near the antenna. A good pre-amp, with RF switching so that you don't accidentally blow it up by transmitting through it, can be had for less than $150 from several manufacturers. Or, there are designs around to roll your own, if you are good at that sort of thing. Good luck, and hope to work you on the linear sats very soon! -- Mark D.

Message-ID: I'm contemplating building a couple of yagis, possibly even crossed ones, and putting them up at fixed elevation (i.e. az-only rotator). What I'm unclear about is how many elements to consider. My location is really pretty dreadful for seeing sky. There's a big hill to the NE that restricts me to above 40 degrees in that direction. I'm in a single-storey house, with neighbouring two-storey houses to the NW, SW, and S. In between all that, there are other single-storey houses, and trees in most of the gaps between houses. I can't afford to put up a tower (and it could never get above the hill anyway), so I'm looking at not too much above my roofline. To at least get through the trees, I'd think more elements would be better. But more elements narrows the beam, and at fixed elevation, that, at some point, will restrict even further how much of the sky I can play with. I'm looking for thoughts on how many elements would be recommended, and how many would be too many, for a fixed elevation, both for VHF and UHF. Ultimately, I'd like to be able to get on the linears, so not limited to the FM sats. Any thoughts would be much appreciated. Thanks in advance. Martin.

In-Reply-To: References: Message-ID: Hi Martin, I think you've analyzed your situation pretty well when it comes to numbers of elements, beamwidths, etc. A few thoughts: - if you can try a few satellite passes from around your property with a handheld yagi, like an Arrow just gain a little first hand experience to see what your minimum elevations are going to look like. - you might be surprised to find that some houses are more "transparent" to VHF/UHF signals than others. There are several ops here who regularly work satellites with portable antennas from inside their houses. Don't consider every obstacle to be impenetrable. With all that said, if I was in your position I'd go for a 3 or 4-element 2m yagi and I'd go to the extra trouble of getting crossed yagis so you can use circular polarization to reduce signal fading. For 70 cm the 7-elements on my Arrow handheld antenna has always been sufficient, and go for crossed yagis again. If you think the trees will really be a problem then go with 4 elements on 2m and a few extra on 70 cm, but realize that if you're buying commercial antennas you're stuck with what the sellers offer. This is about as much as I'd want to swing around with an inexpensive azimuth rotator (You didn't say what kind of rotator it was) Finally, my antenna situation at home was even more awful than yours. My back yard was smaller than my living room and it was surrounded by 3-storey townhouses on all sides. I decided to become a rover and it was the most adventure-packed 2 years of my life! I travelled all over eastern VE3 and western VE2 and activated just over 70 grids, many of which had never been activated before. Amsat ops are always looking for new activations and are very grateful to thos who have the chance to get out there and activate them. I hope this helps a little. You'll get plenty more replies and have lots to sort through soon! 73, Ken Alexander (VE3HLS) So Phisai, Thailand Blog: bueng-ken.com On Sun, Jun 16, 2019 at 2:44 PM Martin Cooper via AMSAT-BB < amsat-bb at amsat.org> wrote: > I'm contemplating building a couple of yagis, possibly even crossed > ones, and putting them up at fixed elevation (i.e. az-only rotator). > What I'm unclear about is how many elements to consider. > > My location is really pretty dreadful for seeing sky.

I was using my Kenwood TM-V71 radio at 50 watts and an Alaskan Arrow II antenna with the last third boom section removed. I didn't hear the bird for the first couple minutes of the pass and couldn't get it to come on myself. Eventually it came on and I heard Clayton W5PFG not long after that so I assume he turned the transponder on. In the first half of the pass it was difficult to get a solid signal into the sat. Other stations had the same problems. Audio was sometimes really low, great other times, and distorted at times as well. The last part of the pass was not bad though. I was able to consistently get a signal into the bird, even at 10 or 5 watts. I had a conversation with Roy K3RLD about this as we were both having the same good luck. This reminded me of past AO-85 behavior where it is easier to get in in the last part of the pass. I was actually on top of a landfill park in my town so I had a perfect view of the horizon and was able to get in all the way to LOS, albeit with some picket fencing effects on the downlink. Stations contacted: W5PFG W5HRH N9XCO * N0RC K3RLD Also heard ???PML * This was Richard N9XCO's first sat QSO. He just finished setting up a IC-9700/G-5500/SatPC32 station One odd thing I noticed is at the end of the pass I believe I was at 145.970 MHz, 10 KHz down from the center frequency of 145.980. It looked so weird I did a double take and doubted I was really at that frequency. I don't know if the bird was off frequency or if it was something on my end.

You can go here if you want to see my setup: http://bx2abt.com/main/Falconsat-3 . I can hit FalconSat-3 with a directory request or file download request and get an immediate response and consequent downloads. Uploading is a different story, however. I have been able to get some messages uploaded, but it was more by chance. Right now if I want to upload I seem to get into a loop where PSGS keeps on sending out the same frame (I presume), then disconnects, after which the whole cycle starts over again. From the PSGS debugging info you can see that I am successful in logging into PFS3-12. My file gets a designated ID (1f14 in this case) and is ready to be received. Then it uploads what I presume is one frame (you can see this in Direwolf where the same chunk of data is send over and over again) after which possibly the reason why things don't work: "ER_BODY_CHECK received while uploading: /home/hans/PacSatGroundData/FalconSat-3/BX2ABT17.txt.out". The only mention of ER_BODY_CHECK I can find on the internet is that it is sent when the checksum on the file body fails. After that the whole sequence starts again, so the message never gets uploaded and out of the queue. Does this problem lie with FalconSat-3, Direwolf or PGSG, or somewhere else? Where is the checksum being made? This is my first forray into packet radio/PacSat, so I'm not an expert (yet). I don't want to make any (un)educated guesses, thus any help or hints are appreciated. Cheers, Hans BX2ABT This is the output (with debugging turned on) of PSGS: --------BEGIN------- Open ABCD: Ready to upload file: BX2ABT17.txt.out B: 209908947.

Again, this may not be the problem at your station at all. But I just thought it is useful to repeat the info. That is why many people do not see themselves on APRS via PFS3, because by the time their rig goes into receive, after transmitting APRS, the digipeat has already occured and they missed it.

However, to add to Bob's thoughts--are you running full duplex? It's critical. Also, is your transmit signal desensitizing your receive signal? That is important, too. In the next week or so I will change radios at my station so I can again use FS-3. I'll be better able to share current experiences with you. 73, Mark N8MH On Mon, Jun 17, 2019 at 9:19 AM Hans BX2ABT via AMSAT-BB wrote: > I'm not behind my shack computer right now, but I know that PSGS and > Direwolf each have a TX delay.

On the occasion of the coronation of His Majesty King Vajiralongkorn Bodindradebayavarangkun, HS10A (pronounced "Hotel Sierra-TEN-Alpha), as the 10th king to reign in the Chakri Dynasty, the National Broadcasting and Telecommunications Commission (NBTC), Thailand's regulator, has authorized the special callsign HS10KING (pronounced "Hotel Sierra-TEN-KING). There will be an opportunity to communicate with HS10KING using the QO-100 amateur radio satellite and low earth orbit (LEO) satellites that windows pass over Thailand by amateur radio stations which is similar to AMSAT Germany's use of the special callsign DL50AMSAT using the QO-100 satellite. RAST hence invites AMSAT amateur radio satellite operators to join in contacting the HS10KING special event station from June 22, 2019 at 10.00 UTC (17.00 Thailand time) until June 23, 2019 at 10.00 UTC (17.00 Thailand time) using SSB mode and DATV (333 - 250 KS) signals from the station HS10KING. Please be informed and let others know of this opportunity.

It is not coax since I tested it with a short piece and analyzer with same results. I had not check the coax stubs yet and thought to write hear first. Any hints will be appreciated.

I am wondering (hoping) that it might have a better elevation pattern than my Cushcraft A270-10S dualband yagi does. On Mode B passes, the satellite has to get to a 25 degree elevation or more before I really have a good chance at getting into the FM satellites. It would be nice to have something that allowed for better success at the lower elevations also. 73 John W5TD (ex AF5CC) From marklhammond at gmail.com Mon Jun 17 19:06:59 2019 From: marklhammond at gmail.com (Mark L. Hammond) Date: Mon, 17 Jun 2019 15:06:59 -0400 Subject: [amsat-bb] M2 Leopack 2Meter swr In-Reply-To: References: Message-ID: Rafael, While not the exact same antenna, I had an SWR problem on an M2 antenna (7 elements vertical yagi) once that drove me nuts until I figured out the problem. This may help you (or others down the road...) The observation was the SWR was high (sometimes it was intermittent, but mostly it was high). The culprit? It was a poor electrical connection between the driven element and the boom! There was "gunk" or corrosion of a type under the aluminum "block" of the driven element that is screwed to the main boom via the stainless steel screw. Using a scratchy Scotchbrite pad on both the block and the main boom, I was able to clean it up and fix the SWR issue. It took me months to determine the cause--I replaced the coax from antenna to preamp, the preamp itself, swapped coax feedlines; I opened up the original driven element, just SURE there had to be a break in the internal wire(s). Nope! I eventually bought another new antenna just like it to swap out the driven element, and finally then did I see what was the apparent cause. It's a case of having to see it myself, to believe it... Rafael, if I was you, I'd at least check the connection of both driven elements to the boom---clean it up well, and see if that fixes it. If not, no harm done...but this is a place that would NEVER have occurred to me previously... Please let us know what fixes your issue! 73, On Mon, Jun 17, 2019 at 1:09 PM Rafael Pena via AMSAT-BB wrote: > Recently, I had my roof done and had to remove the M2 Leopack from the > mast together with the G-5500 Az/El.

The azimuth tracking is manual (usually ahead or behind the satellite). For the most part I'm picking up the FM satellites beacons between 3 and 1/2 degree from the horizon just after updating the Keps and using Gpredict. The drop off as the satellite rises above the antenna beam, but decreases in range, hasn't been a problem. I can tell you from using the set up to bet a bearing on a stuck mike on an APRS WX transmitter that the beamwidth is pretty sharp, I can get the bearing to the stuck mike station consistently (its happened a couple of times) to within +/- 5 degrees using the S meter or better yet the scope display on WSJTX on MSK144. On the 70cm side I'm using an old helix antenna I picked up used over 20 years ago, so my antenna is NOT dual band. As an aside, with the antenna, with or without a preamp on the FM satellites I've had Q5 copy on a pair of stations that couldn't hear well enough to make an exchange to complete the QSO. I have not affiliation with Cubex or any other antenna company. On my QSL I have a photo of my place with the antenna in the back and everything in site covered in a couple of centimetres of hoar frost.

In-Reply-To: References: Message-ID: Hi Juan Carlos, Good question. There are a few reasons I'm leaning towards the DK7ZB designs. No doubt others will have differing opinions, and I'd be more than happy to hear them. * The G0KSC antennas are based on an aluminum boom, whereas the DK7ZB PVC designs are based on a PVC boom (duh!). For a given design (e.g. 5-el 2m), the boom is also slightly longer in the G0KSC design. Those factors mean more weight. I want to keep weight to an absolute minimum to avoid having to deal with stronger cross-boom, stronger mast, stronger rotator, etc. * Related to the aluminum boom, G0KSC makes quite a fuss about the importance of insulators, about the importance of the insulator design, and about the materials used to make the insulators. He even includes links to commercial insulators. Going with a PVC boom, this is a non-issue, since there's no need to insulate the elements from the boom. * G0KSC provides a design that is built with 10mm diameter tubing. DK7ZB provides measurements for several diameters, from 2.4mm to 8mm. This gives me the option to use narrower (thus both lighter and cheaper) material for the elements. If I build X-pols, that's twice as many elements, so it matters. * A while ago, I built an IOio antenna, so I'm quite familiar with having to use a pipe bender to get the tubing bent correctly. It's not easy (at least, it wasn't for me) to get the curves in exactly the right places, trying to measure from the center of one curve to the start of where to bend the next one. Also, with 3/16" tubing, which I used for the IOio, it wasn't too big a deal to twist the tubing when I didn't get two corners exactly parallel to each other. With the larger tubing of the G0KSC design, though, that would be harder. (This is evidenced by the fact that G0KSC even sells loop ends, noting that "The most difficult part of building an LFA Yagi is bending the Loop Ends and getting them right!". So, in short, the DK7ZB designs seem, to me, simpler to build, possibly less error-prone, and will give me very lightweight options, even if I build X-pols. Martin.

If not Direwolf will wait for a free window to throw out packets which will never happen because FS-3 is on all the time. No, everything is working, except for the problem I described before: all commands to the bird are heard and responded to, but uploading a message will fail. Desensing is also not the problem: got the appropriate filters in place for that. Cheers, Hans BX2ABT On 06/17/2019 10:52 PM, Mark L.

I missed getting to use it on a couple of passes today. Jeff Johns WE4B From n4csitwo at bellsouth.net Tue Jun 18 04:58:20 2019 From: n4csitwo at bellsouth.net (n4csitwo at bellsouth.net) Date: Tue, 18 Jun 2019 00:58:20 -0400 Subject: [amsat-bb] Upcoming ARISS contact with King Island District High School, Currie, TAS, Australia Message-ID: An International Space Station school contact has been planned with participants at King Island District High School, Currie, TAS, Australia on 19 June. The event is scheduled to begin at approximately 08:49 UTC. It is recommended that you start listening approximately 10 minutes before this time. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between OR4ISS and IK1SLD. The contact should be audible over Italy and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. King Island District High School is located in the Bass Strait off the North West Coast of Tasmania. We cater for approximately 210 students from Kinder to Year 10. Our school is at the heart of our community, we value each student and their family. We have been striving to create resilient, innovative lifelong learners; our school has been on a learning journey with Literacy and Numeracy as our core fundamentals. Our students have the opportunities for on-island and off-island camps from Year 3 and up, we participate in sporting events in mainland Tasmania, we have students from Kinder to Year 10 being able to access specialist Music and Art lessons. We are grateful to have a well resourced MDT room, Computer Lab, kitchen which has then eventuated into a school caf? 'The Rock Caf?', which offers caf? style lunches, drinks and monthly dinners to our community giving our students first-hand experience of hospitality. We are also in the process of building our own golf hole to fit in with the islands golfing influx of late. Participants will ask as many of the following questions as time allows: 1. Why did you become an astronaut? 2. What training do you need to be an astronaut to go to space and where did you do your training? 3. What sort of food do you eat and how do you determine your meal times in space? 4. What do you do in your spare time so you don't get bored while in space? 5. Does it get lonely in space? 6. How do you exercise in space? 7. How old is the International Space Station and do parts wear out in space like they do on earth? 8. What is your job on the ISS and how do you do it? 9. What are space worms and why are they so important in space? 10. How long does it take to orbit the earth? 11. Have you researched the black hole and if so, how big is it? 12. What kind of research do you do? 13. Do you have any advice for any of our students wishing to follow in your career path?

Rowan Preparatory School, Claygate, United Kingdom, direct via GB4RPS The ISS callsign is presently scheduled to be NA1SS The scheduled astronaut is Nick Hague KG5TMV Contact is go for: Thu 2019-06-20 12:48 UTC Watch for live stream at https://live.ariss.org/ About ARISS Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

Hammond [N8MH] From n4csitwo at bellsouth.net Wed Jun 19 04:09:14 2019 From: n4csitwo at bellsouth.net (n4csitwo at bellsouth.net) Date: Wed, 19 Jun 2019 00:09:14 -0400 Subject: [amsat-bb] Upcoming ARISS contact with Rowan Preparatory School, Claygate, United Kingdom Message-ID: An International Space Station school contact has been planned with participants at Rowan Preparatory School, Claygate, United Kingdom on 20 June. The event is scheduled to begin at approximately 12:48 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and GB4RPS. The contact should be audible over the United Kingdom and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Story: Rowan Preparatory School is a vibrant, friendly and nurturing community where girls are encouraged to be themselves. Our school is an independent preparatory school for girls between the ages of 2 to 11, located in the heart of Claygate (near Esher) in Surrey. A school with traditional values and a forward thinking approach to education, we seek to offer a broad and adventurous curriculum full of exciting opportunities. School life at Rowan is inspiring and offers a breadth of experiences which develop the whole child. The warmth that is evident when you walk through the door at Rowan creates the ideal learning environment for girls to fulfil their potential. They are nurtured and allowed to grow as individuals, encouraged to take risks and have a go at new skills and interests which will enrich their lives. Science, Technology, Engineering and Maths are at the heart of the curriculum at Rowan. Girls make the most of our dedicated specialist teaching spaces and delight in practical learning opportunities in the Engineering and Technology suite. From 3D printers to our radio recording studio, the environment at Rowan is geared towards encouraging creative and exciting learning, ensuring that the girls explore, question and discover in every area of learning. We are passionate about bringing STEM subjects to life and encouraging the girls to see how these subjects translate into the world beyond school. Experiences which will foster successful and inspirational women of the future! Rowan girls are prepared for the transition to a wide range of successful day and boarding schools and we pride ourselves on finding the right senior school environment for each and every girl. A personalised approach to learning and outstanding pastoral care in our happy environment, ensures that every girl develops a genuine love of learning. Participants will ask as many of the following questions as time allows: 1. How did the International Space Station get built when it just balances in the air? 2. What are the challenges to growing food in space if astronauts are to stay in space for longer? 3. Does your digestion change because in space there is no gravity so your intestine will float in your body? 4. Of all the experiments that you have done in space, what has given the most surprising result or has been the most exciting? 5. If you spin a ball in the ISS will it keep spinning or will it stop, and if it stops, what stops it? 6. In the future, will it be possible that someone can spend their entire life in space and if so, would their life expectancy change? 7. If you do a handstand in space does your blood go to your head if there is no gravity? 8. Is there anything you could learn about how bacteria and viruses behave in space that could help us defeat infectious bugs around the Earth? 9. NASA have said that they will establish a permanent presence on the moon within the next decade, how will they do this and what is the most exciting benefit for human kind? 10. In all of your time spent on board the ISS, what is the most exciting and extraordinary thing that you have experienced? 11. What new information about space are you hoping to learn? 12. Can you escape from a black hole? 13. We have learnt that astronauts are very busy and work long hours. So when you have free time, what do you do for fun? 14. How do you get rid of rubbish in space? 15. What are you looking forward to the most in nature when you return? 16. Our teachers and parents tell us that having a balanced diet is important. Is your diet closely monitored or do you have freedom to choose what you eat? What is your favourite meal? 17. How do you sleep in space? 18. What kind of dangers might you experience in space? 19. What is the most beautiful thing you can see in space? 20. We have heard that some people don't believe that the Moon landing took place, what is the best evidence that we have to disprove this theory?

Traverse Area District Library, Traverse City, MI, direct via W8TCM The ISS callsign is presently scheduled to be NA1SS The scheduled astronaut is Nick Hague KG5TMV Contact is go for: Fri 2019-06-28 14:02 UTC About ARISS Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

I came upon two documents with some relevant information. First this is from the document "Pacsat File Header Definition". As it already says, it give a definition: -------BEGIN------- 3.1.9 body_checksum id????????????? :??? 0x09 length????????? :??? 2 data??????????? :??? unsigned int body_checksum A 16 bit checksum formed by adding all bytes in the file body into a 16 bit variable, ignoring overflow.? The does not include the bytes comprising the PACSAT file header. The is primarily intended to detect mis-corrected multi-bit errors caused by Single Event Upsets in the PACSAT memory. INITIALIZATION - The correct must be supplied. -------END------- I don't quite understand the second but last sentence: does the PACSAT memory get upset by my messages? From "Pacsat Protocol: File Transfer Level 0" document more on the upload procedures: -------BEGIN------- 7.4. Completion of Upload 7.4.1 Successful Upload Completion When the server receives the DATA_END packet it will check the integrity of the file as far as possible.? If the checks pass, the server will downlink a UL_ACK_RESP packet. Packet: UL_ACK_RESP Information: none After transmitting the UL_ACK_RESP the server uplink state variable is UL_CMD_OK.? After receiving the UL_ACK_RESP, the client uplink state variable is UL_CMD_OK. 7.4.2 Failure Caused by Server Rejecting Upload The server may reject an upload while the client is sending DATA packets (due to file system problems on the server) or after the client has sent the DATA_END packet (due to corruption of the file). If the server must abort the upload while receiving DATA packets or after receiving the DATA_END checks fail, it sends the UL_NAK_RESP packet. Information: 1 byte ???? unsigned char err_code; ???? must be one of: ER_BAD_HEADER - The file either has no PFH, or has a badly-formed PFH. ER_HEADER_CHECK - The PFH checksum failed. ER_BODY_CHECK - The PFH body checksum failed. ER_NO_ROOM - The server ran out of room for file storage before the upload was complete. The server will implement procedures to avoid frequently running out of room, but this cannot be guaranteed. After transmitting the UL_NAK_RESP packet, the server uplink state variable is UL_CMD_OK.? After receiving the UL_ERROR_RESP, the client uplink state variable is UL_CMD_OK. -------END------- So I clearly get a UL_NAK_RESP packet with the ER_BODY_CHECK error. I also downloaded the PACSAT Ground Station software source code from G0KLA (hello Chris). The hex code for the BODY_CHECKSUM is 0x09. If you search for that in the source code you come up with the file Crc16.java. My coding skills are very minimal, so I don't grok the code completely, but I do see something strange in that file Crc16.java: -------BEGIN------- String s = "HELLO"; ???? byte[] bytes = s.getBytes(); ???? //Crc16 crc = new Crc16(bytes); ???? short cs = 0; ???? for(byte b : bytes) ???? ??? cs += b & 0xff; ???? System.out.println(cs); ???? PacSatField pf = new PacSatField(cs, 0x09); ???? System.out.println(pf); ??? } -------END------- String s is probed for the number of bytes, then "converted" into variable cs, which is the PacSatField 0x09, iow the Body_Checksum. Now string s is simply "HELLO" and I don't see if this is hard coded or that this string changes according to the content of the message body. Any Java programmers here who want to help me look at it? Any help appreciated.

I have ordered and received a coupe of days ago my new one but I cannot get it working Properly on the Falconsat-3 Bird. I explain the problem hoping in some help. I am using SDRSharp - HW Virtual Serial Port - UZ7HO's High Speed Soundmodem - Wisp When I receive the satellite I can see the data incoming in the UZ7HO's High Speed Soundmodem But I do not see nothing in the MSPE ( Wisp ). When I try to transmit I can see the radio going in TX and it remains in TX as locked and get the error form the UZ7HO's High Speed Soundmodem saying: Error opening wave output device (unspecified error). I cannot get in RX again so I need to reset the PC. Please anybody can explain me were am I doing wrong?

I've been having trouble with my Arrow Antenna on the FOX sats. It seems that when I point my antenna at the satellite, say on a 70 degree max elevation pass, it doesn't receive it. But when I point the antenna at the ground, it comes in very clearly. Towards the end of the pass, I start receiving it again because I'm pointing my antenna near the horizon. At this time, I make all of my contacts. What could be the problem? I checked the elements on the antenna and they aren't mixed up.

Just what you need for a GHz-range LEO with a narrow-band transponder, eh? That's exactly what I do in the SDR I've been working on. It uses a Funcube dongle and Raspberry Pi (or any general purpose Linux or OSX system) and applies an optional frequency rate to the digital local oscillator. The Funcube samples at 192 kHz, so you have a lot of room. Right now it can do a quadratic phase function, i.e., it can sweep at a constant rate in frequency, which is a constant acceleration with continuous phase and frequency. (I'll have to think about which order PLL this corresponds to.) It would be easy to extend this to higher orders, but because you can update everything very rapidly (it's all in software) I've seen no real need to do so. Originally the SDR read the velocity data from a pipe, but more recently I've changed over IP multicasting for everything. A completely separate program, which can be on a different computer, multicasts the tracking data to the LAN and the SDRs (there can be more than one) pick it up and make the frequency computations based on the current frequency. It all works very well. I tested it on one of the older Japanese cubesats that transmits a CW beacon on 70 cm. At first I thought I had a bug in my program because the CW shifted every time it started. Then I realized it was just a soft power system in an old satellite; the beacon remained rock steady in a 200 Hz CW filter from horizon to horizon. Naturally this requires accurate elements and clock time. It was a little weird hearing miscellaneous spurs sweep through the passband as the signal stayed in the middle. All said, PSK31 still isn't the best choice for a LEO satellite with a lot of Doppler...

The question about the satellites is how stable those carriers really are. Doing this right requires a 2-way coherent Doppler transponder on the spacecraft. We really should fly one.

FS-3 is a complicated topic because there are a lot of moving parts and everyone's hardware / software setup is different. The key items to get straight are RX-audio, TX-audio, & PTT. All that comes together and it controlled by the UZ7HO High-Speed Soundmodem app, as you mentioned. As a starting point, I'm happy to share the settings that work for my particular RX / TX / PTT setup. Here is a picture w/ comments: https://www.qsl.net/k/k4kdr//how-to/hs_soundmodem_settings.png ... but of course there is a lot more to it. We need to have everything on the RX & TX side set with wide enough audio bandwidth to handle 9600 data, we need to have a COM-port controlled PTT relay, and yet another COM port ID is assigned by the computer via the "HW Virtual Serial Port" app to give the WiSP (MSPE) software what it requires. If that's not enough, since the downlink is constantly transmitting, the "full-duplex" option in UZ7HO HS_Soundmodem needs to be enabled. But as a first step, I hope that the picture of my settings might ring a bell and help you realize what is not working exactly right in your setup. Lastly, for anyone not familiar with FalconSat-3, a very neat feature is that the APRS digipeater -and- BBS both work at the same time. So, you can use something like UISS to send/receive APRS messages, WiSP or the new PacSat Ground Station to upload/download messages posted on the BBS, or both at the same time. All the traffic from both spacecraft services is riding on the same full-duplex 9600 data stream, so both services can be utilized by multiple operators all at the same time during a pass. -Scott, K4KDR ========================= On Wed, Jun 19, 2019 at 2:18 PM Vincenzo Mone via AMSAT-BB < amsat-bb at amsat.org> wrote: > Hi folks, > > I have been off from the satellite for a while due to the broken Funcube > Dongle Pro Plus. > > I have ordered and received a coupe of days ago my new one but I cannot get > it working > > Properly on the Falconsat-3 Bird. > > I explain the problem hoping in some help. > > I am using SDRSharp - HW Virtual Serial Port - UZ7HO's High Speed > Soundmodem > - Wisp > > When I receive the satellite I can see the data incoming in the UZ7HO's > High > Speed Soundmodem > > But I do not see nothing in the MSPE ( Wisp ). > > > When I try to transmit I can see the radio going in TX and it remains in TX > as locked and get the error form the > > UZ7HO's High Speed Soundmodem saying: > > > Error opening wave output device (unspecified error). > > > I cannot get in RX again so I need to reset the PC. > > Please anybody can explain me were am I doing wrong? > > Thanks > > 73 de Enzo IK8OZV > > EasyLog 5 BetaTester > > EasyLog PDA BetaTester > > WinBollet BetaTester > > D.C.I.

The event is scheduled to begin at approximately 14:02 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and W8TCM. The contact should be audible over the state of Michigan and areas within the ISS signal path. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. If you hold your right hand up, palm side facing you, that's what people from the lower peninsula of Michigan use as a reasonable map (just ask Astronaut Christina Koch). Traverse City is situated at the notch formed between your pinky and ring fingers, representing its location at the head of Grand Traverse Bay, part of Lake Michigan. Its location near the 45th parallel region and the Great lakes generally offers warm, mild, summers and severe winters. The Traverse City area is the largest producer of tart cherries in the United States, and each July the city hosts the weeklong National Cherry Festival attracting approximately 500,000 visitors annually. The surrounding countryside also produces hops and grapes, and is one of the centers of wine production in the Midwest. The area features many natural attractions, including freshwater beaches, Sleeping Bear Dunes National Lakeshore, downhill skiing areas, and numerous forests. Arts and cultural activities such as the Traverse City Film Festival, the National Writers Series, and nearby Interlochen Center for the Arts, add to a vibrant quality of life. The Traverse Area District Library (TADL) is a network of six libraries, serving over 90,000 residents of Grand Traverse County. With over 68,000 active cardholders, TADL provides dynamic resources and innovative services to stimulate intellectual curiosity, facilitate lifelong learning, promote literacy, and nurture personal enrichment. This includes many resources and programs to support early literacy. Encouraging exploration and curiosity through STEM and other creative programs for youth. TADL provides access to a variety of materials and services for research, local history collections, learning new or developing existing skills, and much more. Our annual Summer Reading Club program, for readers of all ages, is in full swing. This year's theme is about space and titled: A Universe of Stories. Participants will ask as many of the following questions as time allows: 1. What personal items did you bring with you to space? 2. What does math have to do with space? Do you use addition, multiplication or algebra? 3. What effect does being in space have on the body other than being taller? 4. Does low gravity interfere with your digestive system? 5. How will your new robot, Astrobee, help you work in space? 6. How do you make or store oxygen in space? 7. How do you prevent medical problems in space, and what happens if an astronaut requires emergency surgery? 8. How much space debris is in orbit, and how do you handle it when it comes near the ISS? 9. How many girls go up to outer space? 10. What responsibility and/or efforts is the space program making to protect the ozone layer? 11. How did your military background apply to becoming an astronaut? 12. What do you do with the trash on the ISS? Do you recycle or reuse? 13. Can you see the melting of glaciers and polar ice caps from outer space? 14.

To receive our Twitter updates, follow @ARISS_status Next planned event(s): TBD About ARISS Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

It was a user error.....the culprit Coax or barrel F/F connector (still to check). Prior to finding out the issue, I did remove the special rubber tape from each of the cable connections....clean them...test continuity passed. The only change in my setup, I moved my station from 2nd floor to basement, hence the need to add more coax to both 2m/70cm. I used a F/F N barrel on each coax run and seal them with Dual Wall Adhesive Lined Heat Shrink Tubing. I had mentioned that I did a check right at the antenna feed-point with a small coax jumper...well, this jumper cable had issues also. Yesterday, I removed both 2m/70cm from the roof and brought down to basement for a closer checkup (too hot to be on roof). I used a different jumper coax cable and run test with analyzer attached. Perfect match all across 2m. So I did not try anything else and placed them back on roof. Run the same test with small coax...perfect! This time I swapped the coax and run the same test from the station...perfect! Now 70cm is experiencing high SWR. So I now need to cure this coax by removing heat shrink tubing, barrel removal, etc....test with analyzer. This is a lesson learn that I hope can be of some use for others....and please accept my apologies for the bandwidth.... See you on sats soon!

Para: amsat-bb at amsat.org Asunto: M2 Leopack 2Meter swr Recently, I had my roof done and had to remove the M2 Leopack from the mast together with the G-5500 Az/El. I sat it on the roof floor next to my house. Now that I place it back, the 2M SWR is way high off the sat or regular 2m frequencies 440 is as expected. It is not coax since I tested it with a short piece and analyzer with same results. I had not check the coax stubs yet and thought to write hear first. Any hints will be appreciated. M2 website has a "Blog" which contains only info on Ohm meter testing.

However, the dropdown box which normally shows Model also allows you to select Addresses, which will make the needed boxes active. 73, Alan WA4SCA <-----Original Message----- I'm considering buying another FM HT for the birds, mainly to use as a backup - for demos. (I already have a D72, which is my main unit for personal use and demos right now, and a VX7R, but the latter has seen better days.) For those of you who have attempted to use just a D72 for a demo - with an external speaker as well as the headset/mic - this results in a rat's nest of adapters/connectors/wires. I have the adapter sold on eBay, but unfortunately it attenuates the audio signal (for digital voice recorders), instead of amplifying it for an external speaker , which is what I need. (I guess I could use a powered speaker on that output, but that's one more thing to carry - and power-up! :-) ) So I think *two* radios might work better - wiring wise - for demos. If I buy a Baofeng (or similar), I won't use it for the receive part due to the desense problems on some models (looking at the section in 2019's "Getting Started with Amateur Satellites"). I'm considering the Alinco, since it does have 1.2 Ghz, and using the D72 for receive in that set up (but that still doesn't easily solve the wiring/connector mess for an external speaker/headphones for that radio). Are there other radios which are more "external speaker" friendly which I should consider? I'm open to almost any combination of manufacturers (except for the Baofeng types for receive, as noted above). I'm even open to buying another D72 (but probably hoarding it except for special occasions.) In short, what are your recommendations for a second, spare, radio for the FM birds? I'm also curious how others have wired their single HTs - or two HTs - for demos using an external speaker. So if you could explain - with or without pictures - how you accomplish this, I'd appreciate it.

Put your splitter on the headphone out of the recorder, your headset goes in port one and the external speaker goes in the other. This might work around the attenuation issue as the attenuation is generally to bring it down to line or even mic level which is obviously very low compared to what an external speaker wants. With that said, I'm not sure if the ebay special supports that configuration. I use my own custom cable with some resistors in line. https://spacecomms.wordpress.com/audio-cable-for-kenwood-th-d72/ 73, John Brier KG4AKV On Thu, Jun 20, 2019 at 6:19 PM Philip Jenkins via AMSAT-BB wrote: > > I'm considering buying another FM HT for the birds, mainly to use as a > backup - for demos.

They are actively switching it to L/v. >From ANS: AMSAT Operations Updates AO-85 Status / AO-92 Field Day Plans AO-85's FM repeater is still active during the current period of full illumination. Both downlink and uplink frequencies are off freq- uency low and DUV telemetry is not active. Continued operations are not guaranteed after the full illumination period ends on June 19. Work it while you can! AO-92 will be available in both U/v and L/v for Field Day this year. The current plan is to command AO-92 to L/v on the 0416Z pass on June 22, the evening before Field Day. The 24 hour timer will then run to expiration, and the satellite will revert to Mode U/v for the remainder of Field Day weekend. The planned timing should provide for at least one accessible pass for the continental US in L/v before returning to U/v. If commanding to L/v on the 0416Z pass is not successful, we will reattempt Field Day morning. Please keep the uplink clear during commanding. Additionally, requests were made to the LilacSat-2, IO-86 and PO-101 command stations for special scheduling of these FM repeaters for Field Day. Please watch for these teams? schedule announcements on Twitter and amsat-bb prior to Field Day weekend. Note that IO-86 is only accessible to those stations below about 30 degrees of latitude, but is a very strong repeater and easily worked to the local horizon. The FM repeaters on AO-91 and SO-50 are also expected to be available as normal during Field Day.

Then I make sure to say the call sign of each station I work, so the recorder at least picks that up. I also have a no-name Bluetooth speaker, which also has a jack for a patch cable on the back side.

I found the right-angle plug with the short pigtail, and I can run the pigtail under the strap from the SC-55 soft case that goes over the top of the radio (or under both of those straps, across the top and on one side) to lessen the stress on the radio's speaker jack. Be careful with the selection of adapters for the TH-D72's speaker jack. Some have enough metal and plastic around the plug, where those adapters won't stay plugged into the speaker jack. The one I listed from the Fry's Electronics web site above was the best of the few I originally tried with my TH-D72, and stuck with until I found the Amazon adapter with short pigtail and right-angle plug I referenced previously. With an extension cable, I can have my speaker about 15 feet away from me, but usually am somewhere between 5 and 10 feet from it when I do demonstrations. Even at 10 feet or so away, I can get audio feedback if I transmit with the speaker firing at me, but 5 to 10 feet is usually far enough where I can avoid the feedback. An amplified speaker may be what you need to get a little more volume, without running into the feedback issues. Places like Fry's Electronics should have a selection of those speakers, as would online sources. Good luck, and 73!

It is much easier to obtain a a " Bluetooth" audio transmitter and thus avoid the need for any wires.? ?These transmitters are? reasonable cheap and available from a number of well known sources.Simply plug the Blue tooth Tx into? THD-72 audio jack and pair with the Bluetooth? speaker? - You canadjust the THD-72 volume control to suit your conditions.The size of these Bluetooth transmitters is sometimes smaller than an SDR dongle,? some even have?a wired jack plug fitted. I have used this method not? only for portable operation, but also for demonstrations, It? made it much easier for those listening and myself of course."WIRELESS" Hi Hi.

Adjusting (correcting for) the higher one does a 3x better job at maintaining a constant position with the satellite transponder's passband (which is the objective) than messing with the lower one, but neither is perfect. Best is computer controlling both radios, since both up and downlinks are affected by Doppler. Because of this, it's not simply an administrative decision. Physics can't be legislated.

I personally feel that no info is better than wrong info. And in full disclaimer, I haven't been an AMSAT member or ARRL member for some time because I didn't agree with things, but yet I contribute and try to help those that have operating questions. At least I'm not on an ARRL BB complaining about them and not a member. Gotta go now and try keeping that horse stuff in the stalls.

I am very active on the SSB/CW birds and it makes catching passes very easy. Some day when you want to go completely nuts, build in an audio notifier selectable by satellite, perhps 3 min to AOS have it make a distinctive sound to alert, it's time to sit back down! I would suggest it be tied to the list of sats, currently being "tracked", but with a selection or subset of audio notifications within the full list of stations already marked for tracking. Example: I Track CAS-4A, 4B, XW-2A, 2B, 2C, 2F and also, AO-73, JO-97, EO-88 (for telemetry) and AO-91 and AO-92 for both TLM and Voice. I would like to be "audio notified" for only AO-91 and AO-92 (until I change this setting again). The ability to select out of the main tracking list I use, a subset to be notified about would be quite nice. ...just an idea , the program is great the way it is. 73, and thanks again.

It looks like it provides 95% of all the information I would need when out roving. What I can't find is info about a given satellite's azimuth at AOS and LOS. I do see there's a toggle to display either elevation or Azimuth information but I'm not sure what the azimuth display is telling me. Partial screenshot included. Is there a scale missing on the vertical axis that is intended to show azimuth? If the vertical axis had a scale from 0 to 360 degrees then the display would make perfect sense to me.

Take W3ZM on the Road! Leading up to the 2019 AMSAT 50th Anniversary Space Symposium and General Meeting, to be held in Arlington, VA, October 18 ? 20, 2019, AMSAT?s call sign, W3ZM, will operate from all 50 States, the District of Columbia, and Puerto Rico. Not only is this your chance to get Worked All States-Satellites under the W3ZM call sign, but, also, your chance to be a part of this historic effort. Note: When operating outside of the ?3? call area, operators will append the W3ZM call sign with ?/(call area).? As an example, someone operating from Texas will use W3ZM/5; from Hawaii, W3ZM/KH6; from Alaska, W3ZM/KL7; and from Puerto Rico, W3ZM/WP4. To make this happen ? We need your help! Please volunteer to get on the air and activate your State, using AMSAT?s W3ZM call sign, as well as to cover those States without an active AMSAT Member. Activations of other United States Territories (i.e. Guam, American Samoa, the U. S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands) are also welcome. To volunteer and operate using AMSAT?s W3ZM call sign, you must: Be a current member of AMSAT Obtain permission by emailing AMSAT VP of User Services, specifying the requested date(s) and location(s) Submit an ADIF log of contacts made for upload to LoTW by AMSAT, as instructed in your notice of approval to use the W3ZM call sign [ANS thanks Robert Bankston, KE4AL, AMSAT VP of User Services for the above information] --------------------------------------------------------------------- +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ 2019 marks AMSAT?s 50th Anniversary of Keeping Amateur Radio in Space.

This cubesat will be propelled solely by sunlight, to Earth orbit. LightSail 2 is scheduled to launch aboard a SpaceX Falcon Heavy on June 24, 2019, and we will attempt the first, controlled solar sail flight in Earth orbit. LightSail 2 will ride to space aboard the Department of Defense Space Test Program-2 (STP-2) mission which will send 24 spacecraft to 3 different orbits. LightSail 2 itself will be enclosed within Prox-1, a Georgia Tech-designed spacecraft originally built to demon- strate close-encounter operations with other spacecraft. Prox-1 will deploy LightSail 2 seven days after launch. After a few days of health and status checks, LightSail 2's four dual-sided solar panels will swing open. Roughly a day later, four metallic booms will unfurl four triangular Mylar sails from storage. The sails, which have a combined area of 32 square meters [344 square feet], will turn towards the sun for half of each orbit, giving the spacecraft a tiny push no stronger than the weight of a paperclip. For about a month after sail deployment, this continual thrust should raise LightSail 2's orbit by a measurable amount. LightSail 2 will fly in a 24-degree inclination, 720 km, circular orbit. At latitudes of 42 degrees north it will reach a maximum elevation of 10 degrees above the horizon. Lightsail-2 has been issued an experimental radio license WM9XPA and transmit on 437.025 MHz. A morse beacon will transmit the callsign every 45 seconds. A packet beacon will transmit AX.25, FSK 9K6 bps data. Beacon information is available at: http://tinyurl.com/ANS-153-Lightsail-Morse-Beacon Documentation of the downlink telemetry data structure is posted at: http://tinyurl.com/ANS-153-Lightsail-Telemetry [ANS thanks the Planetary Society for the above information] --------------------------------------------------------------------- NASA Lightsail-2 PR and TV Coverage NASA Television coverage is scheduled for an upcoming prelaunch activity and first nighttime launch of a SpaceX Falcon Heavy rocket, which will be carrying four agency technology missions to help improve future spacecraft design and performance. The launch window for the Falcon Heavy opens at 11:30 p.m. EDT Monday, June 24, from historic Launch Complex 39A at NASA's Kennedy Space Center in Florida. The launch, as well as a live technology show, will air NASA Television and the agency's website. SpaceX and the U.S. Department of Defense will launch two dozen sat- ellites to space, including four NASA payloads that are part of the Space Test Program-2, managed by the U.S. Air Force Space and Missile Systems Center. The four payloads include two NASA technology demon- strations to improve how spacecraft propel and navigate, as well as two NASA science missions to help us better understand the nature of space and how it impacts technology on spacecraft and the ground. Full NASA TV coverage is as follows: (all times EDT) Sunday, June 23 . Noon - NASA prelaunch technology TV show from Kennedy. Subject matter experts will explain each NASA mission and answer questions. Monday, June 24 . 9:30 p.m. - Live NASA TV coverage begins of the return to Earth of NASA astronaut Anne McClain and two other International Space Station residents, with landing scheduled at 10:48 p.m. (Public Channel) . 11 p.m. - NASA TV launch commentary begins ahead of the targeted 11:30 p.m. launch.

During the June 17 event students in the program were provided with two opportunities to learn about space communications from widely different perspectives. The first session was led by Radio Amateur Satellite Corporation (AMSAT) president Joe Spier ? the second by Dave Israel, the Exploration and Space Communications (ESC) projects division?s lead architect. With Spier, SCaN interns got the chance to learn about AMSAT, a volunteer organization that designs, builds, launches and commands amateur radio payloads on satellites. SCaN intern and ?ham? Caitlyn Singam was required to pass a rigorous FCC exam to be given her unique callsign, AC3AG, at the highest level of certification, ?Amateur Extra-class?. Given her history with amateur radio the talk was particularly inspiring. ?I actually ended up talking to Mr. Spier afterwards about getting involved in AMSAT,? Singam said. ?It was really exciting.? Singham enjoyed learning about Spier?s unconventional route to AMSAT, which she related to in her own academic career. ?I?ve had an interesting route myself, with biological sciences and a master?s in systems [engineering] in the fall,? she said. Spier?s route took him from a background in geology to becoming a leader in the small satellite community. He had early dreams of becoming the first to climb Olympus Mons, the highest peak on Mars. Today, he refers to the interns as the ?Mars generation,? hoping that an intern today might summit that peak in the near future. He shared his personal strategy on making big NASA dreams come true: ?I always clarified it by saying, ?If I can?t be that person, I want to help someone else be that person.?? In the afternoon, SCaN interns met with ESC?s lead communications architect for an overview of division projects. Israel?s work at NASA spans 30 years. Interns heard about topics ranging from the development of Tracking and Data Relay Satellites (TDRS) in the late 1980s to the Space Mobile Network, a concept for an interplanetary internet that Israel envisions coming to fruition in the near future. Israel, like Spier, offered the SCaN interns in attendance some advice: ?Never keep any good ideas to yourself, and don?t worry about asking questions from a different perspective,? Israel said. ?A question from a different perspective gets people to think about it in a different sort of way.? "Never keep any good ideas to yourself, and don't worry about asking questions from a different perspective." Dave Israel, ESC Communications Architect To Grace McFassel, a SCaN intern who attended the talk, Israel?s story was not only interesting, but inspiring. ?He [has] this specific skillset that he dearly loves, and he?s used that to carry himself through by finding niches where he can be useful,? McFassel said. ?It?s a good lesson to carry forward.? To learn more about SIP or SCaN, visit NASA.gov/SCaN. To apply for internships, visit intern.nasa.gov.

This is the first time I have used SATPC32 for anything more than AOS-LOS predictions. I still moved the rotor by hand. Have not been able to get the Yaesu cable built to have the LVB tracker control the rotor. May work on that for next year. Used the ICOM IC-9100 and a laptop this year. It worked great to set the frequency for the FM satellites but was horrible for any SSB satellite. I can find myself with the computer turned off. When I tried to use Satpc32, it would jump to somewhere in the passband and no matter how i tried to adjust the radio to find myself, satpc32 had a mind of its own. So, never made an SSB contact. Of course it is more fun to do this during field day with everyone watching. So what is the secret for making Satpc32 see where you have found the sweet spot on the up and down link when you click CAT control instead of doing what it wants? I would have thought it would read the settings from the radio and go from there. After all, it takes me a few seconds to find myself and really easier to adjust for Doppler manually. I wanted to give the automated feature a go for those watching. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards AMSAT Board Member 2016-2020 ARRL Awards Field Checker (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat From ai6do at yahoo.com Sun Jun 23 22:00:28 2019 From: ai6do at yahoo.com (Ryan Noguchi) Date: Sun, 23 Jun 2019 22:00:28 +0000 (UTC) Subject: [amsat-bb] AI6DO Field Day Report References: <1382570195.486436.1561327228562.ref@mail.yahoo.com> Message-ID: <1382570195.486436.1561327228562@mail.yahoo.com> Unlike last year, where I participated in ARRL and AMSAT Field Day concurrently, I did them separately this year.? On Saturday, I worked only satellites for AMSAT Field Day from the vicinity of my home. I never operated from my property, only from other operating positions along my block each optimized for specific pass orientations, all well within an 800 ft circle. All QSOs were made fully pedestrian-mobile, without recharging any of the batteries during the Field Day period.? Most of the FM satellites were a mess, as expected. The one daylight AO-92 L/v mode pass, 20 degrees to the west, was pretty empty, but gave me my first QSO of the day, with WD9EWK. I chose to dual-wield two antennas rather than attach the two together as I've normally done in the past. I strapped the DJ-G7T radio to the handle of the 10-element 23cm EBay yagi, where the PTT button and the VFO A knob were easily adjustable with just my left thumb; in my right hand, I held the Arrow. This worked pretty well, and I found it less fatiguing than having one heavier antenna.? Also made QSOs on PO-101 and AO-85. AO-85 sounded really good, at least for that minute or so I was on. As soon as I got the QSO, I split to go work another pass. Tried LilacSat-2 twice, nothing heard.? The SSB satellites seemed to have few operators on, other than QRO CW stations. On one FO-29 pass, there were two CW stations calling CQ nearly on top of each other and on top of a SSB station calling CQ, while most of the passband was empty. Worked several linear passes, but made only one QSO, and we really had to work for that one. The far-western XW-2 passes were pretty empty.? The packet satellites were underutilized, and could have been a great source of points had more operators been on. Made several QSOs on FalconSat-3 and PSAT, although only one counts for AMSAT Field Day credit. Unfortunately, the ISS digipeater was offline.? Worked a total of 20 passes, although for five of them the satellite was inoperative. Total of 6 qualifying QSOs, half of them with WD9EWK. I had planned to do several more passes that evening and a few more before sunrise the next morning, but I decided to put this day out of its misery and conserve my energy for Sunday.? ? On Sunday morning, I drove to my portable operating location to operate the rest of the Field Day period for only ARRL Field Day. Since I was going to operate 2B1B for ARRL Field Day, I used the same operating category for my AMSAT Field Day contacts for consistency. For the first time, I made a full-time SO2R effort, with one radio dedicated to CW and the other dedicated to FT8. Didn't even try SSB.? Also made one FM satellite contact after 1800z from that operating location for the 100 pt bonus and my sole phone contact for ARRL Field Day.? So, how'd everyone else's Field Day go?? 73, Ryan AI6DO From matthew at mrstevens.net Sun Jun 23 22:21:54 2019 From: matthew at mrstevens.net (Matthew Stevens) Date: Sun, 23 Jun 2019 18:21:54 -0400 Subject: [amsat-bb] AI6DO Field Day Report In-Reply-To: <1382570195.486436.1561327228562@mail.yahoo.com> References: <1382570195.486436.1561327228562.ref@mail.yahoo.com> <1382570195.486436.1561327228562@mail.yahoo.com> Message-ID: the linears were the opposite of empty over here on the east coast... I did 10 passes, making about 40 qsos. The center of the passband on each linear pass was nuts, with 5-10 different stations all calling cq over one another. I used a borrowed 910, and my handheld arrow. It was nice to have the extra power when needed...there was one station in particular that I'm pretty sure had to be running about 300w lol. Every time they keyed up, literally every other station in the passband dropped out. Easiest pass by far was EO-88, I worked N8HM and W4YY, and heard one other station before the transponder shut off. It was interesting to work IO-86, there was a handful of STX and FL stations on, along with the usual south/central american ops. That was a cool opportunity, and hopefully we will have the chance to do that next year too. Thanks to AMSAT Ops for coordinating with the LAPANSAT team to make that possible! 73 - Matthew nj4y/K4LKL On Sun, Jun 23, 2019 at 6:02 PM Ryan Noguchi via AMSAT-BB < amsat-bb at amsat.org> wrote: > Unlike last year, where I participated in ARRL and AMSAT Field Day > concurrently, I did them separately this year.

I started off working under the call sign K5RWK, the Richardson (TX) Wireless Klub, which I am a member. I was able to get a QSO with W5RRR on AO-91.?? Having satisfied the 100- point bonus for the club.?? I switched to my own call sign for the sake of giving demos.?? While I could receive PO-101 fine, I couldn't get a signal into it, so I might need to check what I programmed into my radios.?? Of course, being Field Day, it may have just been being out- classed, power-wise, with my hand-held radios.?? I was able to get two QSOs on two separate passes of AO-85.?? AO-85 was having a lot of problems with all of the use.?? It kept cutting out are coming back after a minute or so.?? I think the drain on the batteries was too much during each pass.?? I believe that it was worse on the second pass.?? I'm concerned about the future of AO-85, considering it is fully out of eclipse.?? I couldn't even get into SO-50, due to the QRM, both unintentional and intentional.?? I believe that this was the worst conditions on the satellites for the four years I've done Field Day.?? That is sad, considering there were more FM satellites available this year than ever before (AO-85, AO-91, AO-92, PO-101, and SO-50). 73, Mac Cody / AE5PH On 6/23/19 5:00 PM, Ryan Noguchi via AMSAT-BB wrote: > Unlike last year, where I participated in ARRL and AMSAT Field Day concurrently, I did them separately this year.??

The secret sauce is to adjust your uplink on the CAT menu until you can hear yourself, then save the uplink calibration. Trying to tune the radio knob caused both the uplink and downlink to change and is not how you calibrate things, but is exactly the behavior you want (manually tuning to find someone to call, and being spot on with your downlink too. I do feel sorry for the folks, hundreds (thousands?), vainly sending dots/dashes during Field Day attempting to find themselves. The secret sauce is to do that before Field Day. With the exception of AO-7 which was unusually far off, all the other dozen+ satellites were within a couple hundred hertz or less of the calibration values I use at home on my 9100 (in a fairly stable thermal environment). Good luck, but rest assured that SatPC32 works great controlling Doppler. 73, Bob, WB4SON On Sun, Jun 23, 2019 at 5:49 PM Bruce via AMSAT-BB wrote: > I bought a Yaesu G5500 to use during field day this year, we got tired > of the arm strong rotor.

Especially the AO-92 L/V contact just after noon. I was getting concerned with being able to make an official Field Day QSO on that pass, after working two others who were not giving Field Day exchanges. It was also good to get you on AO-91 and FalconSat-3 later in the afternoon. I drove to a Forest Service day-use area at Cataract Lake, west of Williams in northern Arizona. Northern Arizona had the best weather for Field Day this weekend than in the past few years, with the temperatures up there never exceeding 75F. My plans were like past years - work both HF and satellites, and have fun doing it. Even though this site is near Williams, and not far from the I-40 freeway, I had no data service on my mobile phone. The phone worked for voice calls and SMS messages, so I used SMS messages to tweet during the day. I don't have my Twitter account set up to forward tweets to my phone, so I was unable to respond until I was in Flagstaff for dinner last night. It took about 2 1/2 hours to make the drive from Phoenix to Williams, and I knew that there was an SO-50 pass coming by a few minutes after the start of Field Day at 11am (1800 UTC). As expected, a busy pass. I heard John K8YSE operating as K8OU through his Arizona station, and that was my first Field Day QSO. I did not use an HT for this pass; I had my Icom IC-2730 dual-band mobile radio, jumpstart battery, and Elk log periodic in a clearing near my site. Five watts, and even 15W, would not work on this and the other FM satellite passes I attempted yesterday not using the 1.2 GHz band. About an hour later, the one AO-92 pass in the L/V mode for Field Day up there. I heard Chris VE7CEW initially, but couldn't get back to him for a QSO. I worked W5SAT and N6NUG before landing a Field Day QSO with AI6DO. I used my two-radio, two-antenna L/V setup like I normally use at home. It worked well as I pointed across the lake and made QSOs, easier than last year's Field Day when I had a smaller 5-element Yagi on top of my Alinco DJ-G7T. I did not try to adjust my transmit power on my DJ-G7T to its low- power setting of 300mW on the 1.2 GHz band, keeping it at 1W for the best possible signals I could send to the satellite. And as the AO-92 pass went away, a very high AO-91 pass came over. Back to the IC-2730, and I cut the string holding the 1.2 GHz Yagi on my Elk, as the AO-91 pass started. Many thanks to Carlos W7QL for a QSO near the end of that pass! After the AO-91 pass, I set up my HF station - Elecraft K3S running on my jumpstart battery at 50W, and a Buddipole dipole. I made some QSOs on 20m SSB before another group of satellite passes came by - PO-101, ISS, and then a low AO-91 pass to my west. PO-101 had a good crowd, but not as crazy as the earlier AO-91 pass. I was able to work Rick VE4AMU for a Field Day QSO. After that, W0IN in Missouri called me, and I made the exchange. Shortly after these QSOs, I switched to the ISS digipeater. Unfortunately, it was off, so no ISS packet this Field Day. AO-91 was coming up for the west coast, and I went on there to help anyone looking to make their Field Day satellite QSO on that satellite. AI6DO was there, and we made a quick QSO. This won't count for me, as I made my AO-91 QSO for points earlier, but I might be a QSO that gets another station their 100-point bonus, or their Field Day QSO on that satellite. Now up to almost 2pm (2100 UTC), I started working 20m and 40m SSB, until a nice FalconSat-3 pass an hour later. I logged a couple of packet QSOs with AI6DO and Brad W5SAT in Las Vegas on that FalconSat-3 pass. This time, W5SAT was ready with a Field Day exchange in the APRS message I received from him. I had two more FalconSat-3 passes that I worked, just before 5pm (0000 UTC) and 6.30pm (0130 UTC), with a single QSO on each of those passes. I tried FO-29 at 5.30pm (0030 UTC), but one station was overpowering the transponder really bad. After a few minutes, I gave up on this pass. I didn't bother to try other SSB passes since it was getting late, and I needed to ensure I left the site by 8pm (0300 UTC) before the gate was locked. I overlooked the NO-84 pass just after 6pm (0100 UTC), a mistake on my part, since packet QSOs using APRS messages have been good for me in past Field Days. I stayed out there to copy the ARRL's W1AW bulletin on 20m SSB just before 7pm (0200 UTC), and then I wrapped up my Field Day effort. I went to Flagstaff to get some dinner, then drove home after that. During the afternoon, I would periodically check the 10m and 6m bands for activity. Nothing was heard on those bands most of the day, but a little before 5pm (0000 UTC) W3AO - a group that loves to put lots of transmitters on the air for Field Days - was barely coming out of the noise. After 2 or 3 minutes of back-and-forth to get information exchanged, I made a QSO with W3AO. This was my first Field Day QSO on 10m in a few years, and worth the extra effort to make the QSO. :-) I still need to get my logs prepared for both ARRL and AMSAT Field Days, as there will be some satellite QSOs in my log that won't count for points in each event. My Field Day QSOs have already been uploaded to Logbook of the World. If anyone wants a QSL card for a QSO from yesterday, please e-mail me directly with the QSO details. I will be happy to send a card, without first receiving a card or SASE from you. 73!

I use another old fox delta serial control interface that emulate GS-232. It has developed a strange problem with the AZ rotor that seems to occur when it reaches the extreme S (past E) where it tends to freeze. The only way to unfreeze it and gain control again is to shut the control box off for a short time and then it will run fine manually or under control by SATPC32. I?m guessing there may be some thermal device inside the rotor itself that is exceeding a limit and needs to cool down. I?d love to hear some suggestions on what the problem might be.

Especially the AO-92 L/V contact just after noon. I was getting concerned with being able to make an official Field Day QSO on that pass, after working two others who were not giving Field Day exchanges. It was also good to get you on AO-91 and FalconSat-3 later in the afternoon. I drove to a Forest Service day-use area at Cataract Lake, west of Williams in northern Arizona. Northern Arizona had the best weather for Field Day this weekend than in the past few years, with the temperatures up there never exceeding 75F. My plans were like past years - work both HF and satellites, and have fun doing it. Even though this site is near Williams, and not far from the I-40 freeway, I had no data service on my mobile phone. The phone worked for voice calls and SMS messages, so I used SMS messages to tweet during the day. I don't have my Twitter account set up to forward tweets to my phone, so I was unable to respond until I was in Flagstaff for dinner last night. It took about 2 1/2 hours to make the drive from Phoenix to Williams, and I knew that there was an SO-50 pass coming by a few minutes after the start of Field Day at 11am (1800 UTC). As expected, a busy pass. I heard John K8YSE operating as K8OU through his Arizona station, and that was my first Field Day QSO. I did not use an HT for this pass; I had my Icom IC-2730 dual-band mobile radio, jumpstart battery, and Elk log periodic in a clearing near my site. Five watts, and even 15W, would not work on this and the other FM satellite passes I attempted yesterday not using the 1.2 GHz band. About an hour later, the one AO-92 pass in the L/V mode for Field Day up there. I heard Chris VE7CEW initially, but couldn't get back to him for a QSO. I worked W5SAT and N6NUG before landing a Field Day QSO with AI6DO. I used my two-radio, two-antenna L/V setup like I normally use at home. It worked well as I pointed across the lake and made QSOs, easier than last year's Field Day when I had a smaller 5-element Yagi on top of my Alinco DJ-G7T. I did not try to adjust my transmit power on my DJ-G7T to its low- power setting of 300mW on the 1.2 GHz band, keeping it at 1W for the best possible signals I could send to the satellite. And as the AO-92 pass went away, a very high AO-91 pass came over. Back to the IC-2730, and I cut the string holding the 1.2 GHz Yagi on my Elk, as the AO-91 pass started. Many thanks to Carlos W7QL for a QSO near the end of that pass! After the AO-91 pass, I set up my HF station - Elecraft K3S running on my jumpstart battery at 50W, and a Buddipole dipole. I made some QSOs on 20m SSB before another group of satellite passes came by - PO-101, ISS, and then a low AO-91 pass to my west. PO-101 had a good crowd, but not as crazy as the earlier AO-91 pass. I was able to work Rick VE4AMU for a Field Day QSO. After that, W0IN in Missouri called me, and I made the exchange. Shortly after these QSOs, I switched to the ISS digipeater. Unfortunately, it was off, so no ISS packet this Field Day. AO-91 was coming up for the west coast, and I went on there to help anyone looking to make their Field Day satellite QSO on that satellite. AI6DO was there, and we made a quick QSO. This won't count for me, as I made my AO-91 QSO for points earlier, but I might be a QSO that gets another station their 100-point bonus, or their Field Day QSO on that satellite. Now up to almost 2pm (2100 UTC), I started working 20m and 40m SSB, until a nice FalconSat-3 pass an hour later. I logged a couple of packet QSOs with AI6DO and Brad W5SAT in Las Vegas on that FalconSat-3 pass. This time, W5SAT was ready with a Field Day exchange in the APRS message I received from him. I had two more FalconSat-3 passes that I worked, just before 5pm (0000 UTC) and 6.30pm (0130 UTC), with a single QSO on each of those passes. I tried FO-29 at 5.30pm (0030 UTC), but one station was overpowering the transponder really bad. After a few minutes, I gave up on this pass. I didn't bother to try other SSB passes since it was getting late, and I needed to ensure I left the site by 8pm (0300 UTC) before the gate was locked. I overlooked the NO-84 pass just after 6pm (0100 UTC), a mistake on my part, since packet QSOs using APRS messages have been good for me in past Field Days. I stayed out there to copy the ARRL's W1AW bulletin on 20m SSB just before 7pm (0200 UTC), and then I wrapped up my Field Day effort. I went to Flagstaff to get some dinner, then drove home after that. During the afternoon, I would periodically check the 10m and 6m bands for activity. Nothing was heard on those bands most of the day, but a little before 5pm (0000 UTC) W3AO - a group that loves to put lots of transmitters on the air for Field Days - was barely coming out of the noise. After 2 or 3 minutes of back-and-forth to get information exchanged, I made a QSO with W3AO. This was my first Field Day QSO on 10m in a few years, and worth the extra effort to make the QSO. :-) I still need to get my logs prepared for both ARRL and AMSAT Field Days, as there will be some satellite QSOs in my log that won't count for points in each event. My Field Day QSOs have already been uploaded to Logbook of the World. If anyone wants a QSL card for a QSO from yesterday, please e-mail me directly with the QSO details. I will be happy to send a card, without first receiving a card or SASE from you. 73!

Eventually, realized that adjusting the downlink instead was a better choice, and has been smooth sailing since.? Technically speaking, the calibration of the downlink takes care of abnormalities in the entire chain and that lets the program (SatPC32 etc.) ensure that the uplink is spot-on any time you pan the downlink, during the pass.?

I do feel sorry for the folks, hundreds (thousands?), vainly sending dots/dashes during Field Day attempting to find themselves. The secret sauce is to do that before Field Day.? With the exception of AO-7 which was unusually far off, all the other dozen+ satellites were within a couple hundred hertz or less of the calibration values I use at home on my 9100 (in a fairly stable thermal environment). Good luck, but rest assured that SatPC32 works great controlling Doppler. 73, Bob, WB4SON On Sun, Jun 23, 2019 at 5:49 PM Bruce via AMSAT-BB wrote: > I bought a Yaesu G5500 to use during field day this year, we got tired > of the arm strong rotor.

So today for the first time in my 10 years as an amateur radio operator I experienced that my KR-400 rotator (partially) stopped working. It has not been in use for 10 years, only the last 8 months and the motor was cleaned and greased before the install. Before I start dismantling everything I would like to see if any of you have any good advice. The problem --- it will turn right, not left. What I measured --- between terminals 5 and 6 (right turn) I measured 31 Volts, which is normal. Between 4 and 6 (left turn) only 21 Volts. Rotor not connected to the controlling box when measuring. My thoughts --- must be in the controlling box. However, there is simply nothing there in the circuit that I think could act up. From the transformer one terminal carrying 29 Volts goes to two switches. The other terminal is neutral. There is the light bulb between the two terminals and a 70 uF/50V capacitor between the two switches. I could be entirely wrong, so spill any info and/or tips that you can give me, here.

See my listing in the 'Zed forums here: https://forums.qrz.com/index.php?threads/icom-821h-all-mode-vhf-uhf-radio-few-accessories.663540/ I'd love to see this rig go to another AMSAT member and keep on getting used to work the birds for the rest of time.

The biggest issue I have with an external recorder is the rats nest. The main reason that I'm still using dual radios, with the D74a being the receiver. With a built in recorder, it is 1 less cable, and about 4 points of failure removed from the setup. My FM setup has 1 audio cable coming from the RX radio and coax going to the TX radio. If I had a shorter headphone cable it would be great, but the ones that I have been using require a TRRS splitter which the shortest I have found is 6", so the cable is still longer than needed. ... Back to the original topic, the 2nd radio. For the cost of most HT's either used or new that have a good/decent receiver, you can nearly get a "duplex" mobile radio and at the same time get those extra watts needed for the weekend FM pass demo's. I am have been thinking about selling my D72, which I use as a TX radio, and go this route.

I have yet to work anyone on EO-88. Passes in eclipse are normally past my night-night time.? I think you're right, on some of those passes I was on, QRO CW stations may have been overwhelming the transponder. They certainly overwhelmed my ear when I had the volume turned up to try to copy the SSB stations beneath them.? Perhaps the AMSAT Field Day rules should be revised to discourage CW on the satellites if folks can't keep to responsible power levels. I like to work CW on HF, but I don't suck all the life out of the ionosphere when I key up.? 73, Ryan AI6DO On Sunday, June 23, 2019, 3:22:03 PM PDT, Matthew Stevens wrote: the linears were the opposite of empty over here on the east coast... I did 10 passes, making about 40 qsos. The center of the passband on each linear pass was nuts, with 5-10 different stations all calling cq over one another. I used a borrowed 910, and my handheld arrow. It was nice to have the extra power when needed...there was one station in particular that I'm pretty sure had to be running about 300w lol. Every time they keyed up, literally every other station in the passband dropped out. Easiest pass by far was EO-88, I worked N8HM and W4YY, and heard one other station before the transponder shut off.... - Matthew nj4y/K4LKL From bruninga at usna.edu Tue Jun 25 03:11:49 2019 From: bruninga at usna.edu (Robert Bruninga) Date: Mon, 24 Jun 2019 23:11:49 -0400 Subject: [amsat-bb] PSAT2 launch delayed to 0230 EDT Tuesday Morning Message-ID: Rumor has PSAT2 launch delayed to 0230 EDT Tuesday Morning Bob From pconver at gmail.com Tue Jun 25 04:32:37 2019 From: pconver at gmail.com (Pedro Converso) Date: Tue, 25 Jun 2019 01:32:37 -0300 Subject: [amsat-bb] Pre-launch TLE's for PSAT2 In-Reply-To: <6ca11a8956def8a3e725b542ba526862@mail.gmail.com> References: <6b4abc54c9e4ea22afcd83ba587fca91@mail.gmail.com> <6ca11a8956def8a3e725b542ba526862@mail.gmail.com> Message-ID: Hello Bob, Thanks for info on launch delay, updated keps with new time on: http://amsat.org.ar/pass?satx=psat2 73, lu7abf, Pedro On 6/24/19, Robert Bruninga wrote: > Just heard of a 3 hour launch delay. > Bob > > -----Original Message----- > From: Pedro Converso > Sent: Monday, June 24, 2019 9:22 PM > To: Robert Bruninga > Cc: AMSAT-BB > Subject: Re: [amsat-bb] Pre-launch TLE's for PSAT2 > > Thanks Bob, > > For PSAT2 pre-launch Keps, using them on > > http://amsat.org.ar/pass?satx=psat2 > > Trying show first orbits. > > Good Luck on launch ! > > 73, lu7abf, Pedro > > On 6/24/19, Robert Bruninga via AMSAT-BB wrote: >> PSAT2 >> 1 99999U 19176.15625000 .00001426 00000-0 27052-4 0 00004 >> 2 99999 028.4525 150.8888 0388671 088.0149 091.1931 14.93486277000010 >> >> But when we play that forward to launch time, the satellite is about >> 10 minutes ahead of the launch.

Rafael Reif issued the following statement today to all members of the MIT community, including yours truly. Reif, himself a Venezuela-born US citizen whose parents emigrated from Europe in the 1930s to escape Nazism, received his PhD from Stanford University and is a recognized authority in information technology.? He has been president of MIT since 2012. In his letter, he draws attention to the global nature of the MIT community and its foundation as a meritocracy, as well as the need to protect against academic espionage wherever it may occur.? Like MIT, AMSAT and amateur radio itself are global communities, whose members think for themselves about the issues Reif is raising, and develop their own points of view. For this reason, I am circulating Reif's message for your information and without further comment. 73 Ray W2RS -----Original Message----- From: President L. Rafael Reif To: rsoifer Sent: Tue, Jun 25, 2019 8:46 am Subject: Immigration is a kind of oxygen #yiv2554181767 #yiv2554181767divHostedEmailLink {margin-bottom:15px;text-align:center;font-family:Arial, Helvetica;font-size:11px;} #yiv2554181767 #yiv2554181767divHostedEmailLink a {color:#ce1126;} #yiv2554181767 p.yiv2554181767foot{color:#8A8A8A !important;font-size:60% !important;} #yiv2554181767 p.yiv2554181767foot a{color:#ce1126 !important;}#yiv2554181767 table td{border:0px;} | | To the members of the MIT community, MIT has flourished, like the United States itself, because it has been a magnet for the world?s finest talent, a global laboratory where people from every culture and background inspire each other and invent the future, together. Today, I feel compelled to share my dismay about some circumstances painfully relevant to our fellow MIT community members of Chinese descent. And I believe that because we treasure them as friends and colleagues, their situation and its larger national context should concern us all. The situation As the US and China have struggled with rising tensions, the US government has raised serious concerns about incidents of alleged academic espionage conducted by individuals through what is widely understood as a systematic effort of the Chinese government to acquire high-tech IP. As head of an institute that includes MIT Lincoln Laboratory, I could not take national security more seriously. I am well aware of the risks of academic espionage, and MIT has established prudent policies to protect against such breaches. But in managing these risks, we must take great care not to create a toxic atmosphere of unfounded suspicion and fear. Looking at cases across the nation, small numbers of researchers of Chinese background may indeed have acted in bad faith, but they are the exception and very far from the rule. Yet faculty members, post-docs, research staff and students tell me that, in their dealings with government agencies, they now feel unfairly scrutinized, stigmatized and on edge ? because of their Chinese ethnicity alone. Nothing could be further from ? or more corrosive to ? our community?s collaborative strength and open-hearted ideals. To hear such reports from Chinese and Chinese-American colleagues is heartbreaking. As scholars, teachers, mentors, inventors and entrepreneurs, they have been not only exemplary members of our community but exceptional contributors to American society. I am deeply troubled that they feel themselves repaid with generalized mistrust and disrespect. The signal to the world For those of us who know firsthand the immense value of MIT?s global community and of the free flow of scientific ideas, it is important to understand the distress of these colleagues as part of an increasingly loud signal the US is sending to the world. Protracted visa delays. Harsh rhetoric against most immigrants and a range of other groups, because of religion, race, ethnicity or national origin. Together, such actions and policies have turned the volume all the way up on the message that the US is closing the door ? that we no longer seek to be a magnet for the world?s most driven and creative individuals. I believe this message is not consistent with how America has succeeded. I am certain it is not how the Institute has succeeded. And we should expect it to have serious long-term costs for the nation and for MIT. For the record, let me say with warmth and enthusiasm to every member of MIT?s intensely global community: We are glad, proud and fortunate to have you with us!?To our alumni around the world: We remain one community, united by our shared values and ideals! And to all the rising talent out there: If you are passionate about making a better world, and if you dream of joining our community, we welcome your creativity, we welcome your unstoppable energy and aspiration ? and we hope you can find a way to join us. | | *? ? ?? ? ? ? ? ?*? ? ?? ? ? ? ? ?* | | In May, the world lost a brilliant creative force: architect I.M. Pei, MIT Class of 1940. Raised in Shanghai and Hong Kong, he came to the United States at 17 to seek an education. He left a legacy of iconic buildings from Boston to Paris and China to Washington, DC, as well as on our own campus. By his own account, he consciously stayed alive to his Chinese roots all his life. Yet, when he died at the age of 102, the Boston Globe described him as ?the most prominent American architect of his generation.? Thanks to the inspired American system that also made room for me as an immigrant, all of those facts can be true at the same time. As I have discovered through 40 years in academia, the hidden strength of a university is that every fall, it is refreshed by a new tide of students. I am equally convinced that part of the genius of America is that it is continually refreshed by immigration ? by the passionate energy, audacity, ingenuity and drive of people hungry for a better life. There is certainly room for a wide range of serious positions on the actions necessary to ensure our national security and to manage and improve our nation?s immigration system. But above the noise of the current moment, the signal I believe we should be sending, loud and clear, is that the story of American immigration is essential to understanding how the US became, and remains, optimistic, open-minded, innovative and prosperous ? a story of never-ending renewal. In a nation like ours, immigration is a kind of oxygen, each fresh wave reenergizing the body as a whole. As a society, when we offer immigrants the gift of opportunity, we receive in return vital fuel for our shared future. I trust that this wisdom will always guide us in the life and work of MIT. And I hope it can continue to guide our nation. Sincerely, L.

The PSK31/SSTV downlink appear to be working well on 435.350+/- Doppler, But you will only see SSTV during daylight passes (Now occuring in the Southern Hemisphere) where the Solar charge voltage is above threshold (6.8 volts. THen you should see SSTV images once every 4 minutes automatically while in the sun. Northern Hemisphere passes are presently occurring overnight and PSAT2 is in a 28 degree orbit and not seen at all by high northern latitudes and most of Europe :-( PSAT2 APRS digipeating will remain off indefinately while all these other NEW modes are working. Do not TX any APRS packets on the uplink. DTMF Grid Uplinks-to-APRS/Voice will be enabled LATER. While waiting, spend the next day familiarizing yourself with the PSAT2 APRStt touchtone mode. This mode will let you send DTMF Grid square reports which are translated to VOICE and to an APRS packet on the 145.825 downlink. Be sure to prepare your radio with your pre-programmed DTMF grid report IN ADVANCE. And learn how to send Touchtone from your radio's DTMF memory. quickly! It should take under 4 seconds. Do not even think of sending it manually. Here is WA7MXZ's translator to calculate your onetime DTMF grid report: http://aprs.org/aprs_translator.htm See how it works in about the middle of the PSAT2 page: http://aprs.org/psat2.html A successful DTMF uplink will result in a Voice response and an APRS packet on the downlink for display on APRS radios. Again, no APRS Uplink in this mode. This will be painful because of the 4 second uplink transmissions all colliding on the half-duplex uplink, so PLEASE only attempt your DTMF uplink once every 30 seconds or longer to give others a chance. And of course NOT while PSAT2 is downlinking. We will advise when this mode is enabled. http://aprs.org/aprstt.html Bob, WB4APR From n8hm at arrl.net Tue Jun 25 22:58:53 2019 From: n8hm at arrl.net (Paul Stoetzer) Date: Tue, 25 Jun 2019 18:58:53 -0400 Subject: [amsat-bb] PSAT2 Future Operations In-Reply-To: References: Message-ID: Bob, Two questions: What is the SSTV modulation used?

What is amazing, is that it looks like it is about the SAME time every day for a pass even though the orbit is moving earlier After a few days, there will be a new orbit around 8 PM local time, and the others above will continue at the same time. And so forth. So it is moving earlier but appears to have this sun synchronous behavior...

Then every 4 minutes the SSTV signal is present so if you plan experiments in PSK transponder, try to stay between the beacons and SSTV. Description of modes you can find at https://github.com/alpov/PSAT-2/blob/master/README.md We would be glad to answer any questions about this experiments. We are still awaiting for any positive confirmation of downlink signal at 435.350MHz as for us it is still below horizon. Any audio recordings, IQ data or at least pictures of reception would be welcomed. ?????????? 73!

He has posted the beacon on twitter @JA0CAW. Thanks also to Scott, K4KDR for connecting the dots for us! This is the first beacon heard for our satellite!!!Our team is currently still working on stations and a decoder to post on github for everyone, we just need to verify with the University that it's alright to do so.For now, our beacon features our vehicle's callign is ascii and quotes from the video game "Portal", so give us a listen! Based on info from CalPoly and from PSAT, we think we are either Object J or Object K in the database, 44347 or 44348.Parameters again are 437.525MHz DL, 19200 baud, GFSK, beacons every 10 seconds, vehicle callsign WH2XYR. Overall we are inexperienced with respect to interacting with the amateur community (and building satellites for that matter) but we already owe everyone a lot for helping us find our satellite while we are indisposed, SO THANK YOU VERY MUCH!

Message-ID: <1ea3112c44bbb6b199a02cbc1babc7a6@mail.gmail.com> PSAT2 is coming to the Northern hemisphere! After reviewing the orbit, it is somewhat time synchronous, meaning each orbit time (at mid northern latitudes) is just 5 minutes later each night. But then a NEW earlier orbit appears 90 minutes earlier every other day. So, by the 4th of july, one week from now, PSAT2 first pass will be as early as 4 PM local time... (in the Northern Hemisphere mid latitudes) And the Apogee moves rapidly, In just two weeks, Apogee will be over the northern hemisphere giving higher latitudes much better access. At launch it was the middle of the night and perigee was in the Northern hemisphere making it only visible for lower latitudes. So things will improve for Northern Hemisphere .... (and then two weeks get worse, etc)... 24 Hour telemetry plots (links to FINDU.COM) are now available on the http://aprs.org/psat2.html page.

The ionosphere can bend your uplink down so that it does NOT hit PSAT2 when it is low on the horizon. On the other hand, at the horizon, it might also at times bend just enough to extend the footprint. But you wont hear the UHF downlink to know... So I suspect, the ionosphere will be more in the way than not. Just a wild guess. With the same PSK31 transponder having been on 100% for over 2 years with the original PSAT (NO84), there has not been enough users to really know what happens. It also downlinks on the same frequency. (but uplinks in the normal ten meter PSK band at 28.121) so if there are ANY users at all on 10m then they will bring up the transponder. But on PSAT2, the IARU decided all uplinks must be in the satellite band and we had to m ove the uplink to the exclusive 29.481 frequency.

With only a long wire HF antenna (http://myantennas.com/wp/product/efhw-8010/) suspended around 4 meters off the ground, I have often seen my PSK31 TX stream coming back down on the 70cm FM downlink at as little as 10 deg. elevation. However, this time of year with leaves on the trees, it needs to be closer to 20 deg., but that's still pretty good. So yes, I'm hopeful that I can be heard w/ a 10m uplink even while PSAT-2 is still in that southern phase of its orbital pattern. If PSAT-2 works anywhere near as good as PSAT does, it's going to be really hard to resist putting up a dedicated 10m antenna such as the PAR HF-28! -Scott, K4KDR ======================================== From: Robert MacHale Sent: Thursday, June 27, 2019 1:52 PM To: AMSAT BB ; Scott Subject: Re: [amsat-bb] SSTV from PSAT-2 Scott, Just curious -- Does the 10m uplink have any bounce/skip off the atmosphere?

The hams at BRNO University delivered the PSK31/SSTV module for PSAT2 on-time and on-budget (free to us). They worked over the holidays to meet a very short deadline and delivered in February 2017 for a March Integration. Then 2+ years of launcher and FCC delays and it finally got launched now! I guess whenever I powered it up, it must have been taking pictures. Im sure it was frustrating for them to see all the launch delays, but each was only a few months and so there was no time (and risk was too high) to send it back to the Czech Republic for them to do any more tweaks...

After verifying it would drop with inactivity, a few QSOs were made before LOS. Currently, the battery voltage is very low and it looks like we have a cell about to give up the ghost. Please do not use the satellite while it is in eclipse, even if you hear it OK. We are not sure what will be usable if and when this cell fails completely.

The 28 degree inclination makes it difficult to work it over most of Europe but the significant difference in apogee and perigee can make a 15 degree or so elevation difference on the horizon. When apogee circulates to be over the northern hemisphere, then more northern stations can work it. When Perigee is over the northern hemisphere, it can only be seen in Spain and Italy latitudes in Europe, and only mid latitudes in the USA. This changing apogee dynamic will move earlier each day and two weeks later, will have reversed, and so forth on a monthly cycle or so. Another interesting thing about the orbit is that it is almost time synchronous; meaning that a pass will occur almost the same time every day (though five minutes earlier). But then an earlier orbit will appear an hour and a half earlier every other day. This makes it very easy to do mobile/portable operations without any computer once you hear one pass. Operating Modes PSAT2 consists of a number of exciting and unique Amateur Radio Communications transponders: - First is a newer PSK31 29 MHz uplink/UHF FM downlink from Brno University following on to the original on PSAT. - Second is a Brno SSTV camera that downlinks in the same UHF FM waterfall as the PSK31 users. - Third is a DTMF grid square uplink and voice/APRS downlink for grid position reporting. - Fourth is DTMF Text messaging (APRStt). - Fifth is APRS text messages up and voice down. - Sixth is a conventional APRS digipeater that will join a number of sister APRS Amateur Satellite transponders. Currently the HF/UHF PSK31 and SSTV modes are enabled and open to users. But the VHF modes have not been enabled for users and users are requested to keep the uplink clear during on-orbit testing. PSAT2 is designed for maximum orbit life compared to other similar sized cubesats because it is flying with the maximum allowable mass. Almost a kilogram of lead ballast about 2cm x 8cm x 8cm located in the center of the cubesat constitutes almost HALF the satellite's mass to give it a high ballistic coefficient to last longer on orbit. One of the most interesting and unique features of PSAT2 is the new APRStt (Touchtone) DTMF/voice transponder which lets everyone do APRS using any radio with DTMF keypad, not just those with APRS radios. There have been several iterations of the APRStt system in APRS over the years since 2001, but this application will be new in space and will help introduce everyone to this unique alternate APRS capability for use with ANY radio. Operating Frequencies - APRS Up/Down: 145.825 1200 baud APRS (like ISS, PSAT, AISAT-1) - DTMF Uplink: 145.980 MHz (Voice confirmation down on 145.825 MHz) - PSK31 Downlink: 435.350 MHz +/- 5 kHz FM (300 mw) - PSK31 Uplink: 29.4815 MHz PSK31 SSB (25 W and omni vertical typical) PSAT2 Digipeater Aliases To join the existing APRS satellites on orbit and operate as a seamless constellation, PSAT2 supports the same APRSAT and ARISS generic aliases as the original PCSAT (NO44) PSAT and the packet system on the ISS so that users do not have to change any parameters when using any of these three APRS transponders. Complete PSAT-2 information is available at: http://aprs.org/psat2.html The PSAT2 User Manual is available for download at: aprs.org/PSAT2/USER-Operations-Manual.doc [ANS thanks Bob Bruninga, WB4APR for the above information.] -------------------------------------------------------------------- Update: PSAT2 is coming to Northern Latitudes! After reviewing the orbit, it is somewhat time synchronous, meaning each orbit time (at mid northern latitudes) is just 5 minutes later each night. But then a NEW earlier orbit appears 90 minutes earlier every other day. So, by the 4th of July, PSAT2 first pass will be as early as 4 PM local time in the Northern Hemisphere mid latitudes. And, the apogee moves rapidly. In just two weeks, apogee will be over the northern hemisphere giving higher latitudes much better access. At launch it was the middle of the night and perigee was in the Northern hemisphere making it only visible for lower latitudes. So, things will improve for Northern Hemisphere... then two weeks get worse, etc. 24 Hour telemetry plots (links to FINDU.COM) are now available on at http://aprs.org/psat2.html.

This provides an opportunity to image the eclipse with the Chinese lunar orbiting Amateur Radio satellite Lunar-OSCAR 94 (aka DSLWP-B). An attempt will be made to image the eclipse with the Inory eye camera on- board, where both the Moon and Earth should appear in the images. The main interest is to photograph the shadow of the Moon on the surface of the Earth. The camera doesn?t have a large resolution and the Earth will look small in the image, but it will be possible to distinguish the shadow clearly. Because the satellite aims its solar panel towards the sun, the camera on-board DSLWP-B is always pointing away from the Sun. Since DSLWP-B orbits the Moon, the Earth will always be in the center of the camera field of view during a solar eclipse. However, it might happen that the Moon is between the satellite and the Earth thus hiding the view of the Earth.

During the sessions, Kenwood software manager, Shin Aota presented two Kenwood TM-D710GA transceivers to ARISS Russia delegate Sergey Samburov. A TM-D710GA will be used to replace aging amateur radio equipment on board the International Space Station. For several weeks, these radios have undergone detailed qualification testing followed by software configuration and verification. With today's transfer of the radios to ARISS Russia, we are one step closer to an enhanced Amateur Radio system on board the ISS supporting various operations such as SSTV, voice communication, APRS and a variety of experiments.

ESA Education runs the European Astro Pi Challenge which allows students to conduct scientific investigations in space, by writing computer programs. A record-breaking number of more than 15000 people, from all 22 ESA Member States as well as Canada, Slovenia, and Malta, took part in this year?s challenge across both Mission Space Lab and Mission Zero. After designing their own scientific investigations and having their programs run aboard the International Space Station, the Mission Space Lab teams spent their time analyzing the data they received back from the ISS. To complete the challenge, they had to write a short scientific report discussing their results and highlighting the conclusions of their experiments. We were very impressed by the quality of the reports, which showed a high level of scientific merit. the Astro Pi jury has now selected eleven winning teams, as well as highly commending four additional teams. The eleven winning teams won the chance to join an exclusive video call with ESA astronaut Frank De Winne, head of the European Astronaut Centre in Germany where astronauts train for their missions. Each team had the once-in- a-lifetime chance to ask Frank about his life as an astronaut.

This version has a few tweaks most requested by users: - Key display settings can be changed on the main window from a set of icons bottom left. e.g. showing spacecraft in eclipse vs sun. - Horizontal lines for 30 and 60 degrees can be displayed. - Horizontal lines for all labels on the vertical axis can be displayed. - Time labels have a slightly more sensible gap between them (e.g. 15 minutes) rather than a random amount that fit in the window (such as 13 minutes). - Past minutes can now be as short as 10 minutes, although a longer period can be selected.

Bob has updated his Mobile LEO tracking site to show graphically how PSAT2 orbit works at http://aprs.org/MobileLEOtracking.html. Bob adds, "It's easy to remember. Five minutes later per day, but a new orbit an hour and a half earlier every other day. This is approximate but time will tell. "If you are in the wilderness, just monitor 145.825 and when you hear PSAT2, then you can easily guess all orbits in the future."

Message-ID: <1085691148.482152.1561915294678@connect.xfinity.com> Hi all: I apologize in advance because I know this question was answered on this bb before, but I simply cannot find it. Can't find it in the docs, either. The question: I want to use SatPC32 to automatically switch satellite frequencies on an RSP1 SDR. I know there is an interface program (vspMgr) that makes SatPC talk to HDSDR (and HDSDR commands the RSP1; that part works well) but I can't find the details on how to make it work. Help, please.
