Message-ID: <6f46076fd3ddb062d3391f1c306ad20c@mail.gmail.com> We need more Tracking Satgates in the eastern USA: During the last pass Solidly over Eastern USA and dozens of packets and many users, only two packets made it to the APRS-IS. So there seems to be a paucity of Oscar class SatGates at the moment.. Of course tracking and gain antennas are not needed for SatGates for the ISS, but are essential for PSAT. So if anyone in the USA has rotors and wants to exercise them and put a little wear and tear on them for the next week or so, please feel free to come on line. We are trying to get PSAT properly set up for its attitude control and for it to know where it is, and we need more data for a while. We are getting solid data horizon to horizon over Europe, but very little over the USA. I completely understand the usual need not to keep rotors running for routine. That is why we want to develop the Omni Satgates. But until we get enough of them on line, we welcome more conventional tracking SatGates for a while.

I will be driving to southern California next Thursday (9 July), in advance of a presentation I will give for the Escondido Amateur Radio Society that evening. After that presentation, and after spending the next day (Friday, 10 July) in and around San Diego, I will head north. Other than a planned stop at the DM04/DM05 grid boundary north of Los Angeles (the same spot I stopped at last September, near Mojave CA and Edwards AFB), I am probably going to head further north. I don't have to be back home until the following Monday (13 July) evening, so I have some time to go either north through the San Joaquin Valley, or over to the Pacific coast, or some sort of loop to see a lot more of central California. I have not set an itinerary for the portion of my trip after the DM04/DM05 stop, but have asked other satellite operators via Twitter for feedback on some grids that I could visit while I am on the road. I'm now asking the grid hunters here on the -BB the same thing. If I look to go up or down the Pacific coast, grids I could visit include CM94 through CM96, and possibly even as far north as Santa Cruz and the almost-all-wet grid CM86. If I stay inland, DM0x grids would be where I'd probably drive through. I'm not planning to go all the way up to the Bay Area, although Santa Cruz is not that far from San Jose. Any thoughts from the crowd here, on grids that I should try to visit between 11 and 13 July? On my way back to Phoenix on 13 July, I may be able to make a stop on the DM23/DM24 boundary, either north of Quartzsite on the Arizona side of the Colorado River, or just across the river along US-95 in California. This stop will depend on whether or not a satellite pass is available when I go through that area. I won't be driving I-10 on my way to San Diego on 9 July, so I won't be able to make this stop early in the trip. While on the road, I plan on running APRS using WD9EWK-9, which should be visible on sites like http://aprs.fi/WD9EWK-9 . I'll also use my @WD9EWK Twitter feed to post updates, even if I can only send SMS messages with those updates. QSOs will be uploaded to Logbook of the World. Thanks in advance, and 73!

These ARISS contacts are complicated and highly coordinated and if random hams are trying to call the ISS, even though the scheduled contacts use confidential uplink frequencies and not the public uplink, you never know if it could confuse or interfere with an astronaut or cosmonaut who isn't trained primarily to make these contacts with schools. Afterall, they are done during their free time, and if it becomes exceedingly difficult to make contacts with schools and there is little reward, they are more likely to not provide the time to do it at all. I recommend not trying to call the ISS before, during, or after an official ARISS contact. If you really want to make contact, you could encourage a local school to submit an application, work with them as a mentor, and be the first person who initiates the contact before handing the mic over to the students. Such a good idea I might even do it myself.

Plenty of energy. The PSK31 transponder is on all the time in AUTO mode as long as there are users in the 10m uplink passband. Doppler is a challenge for some stations depending on geometry to the pass. Question? Have we had any success in PSK31 authors to include Doppler correction in their software? KO6TZ provided a table summary of various PSK programs and their capabilities on the PSAT web page. Ideal satellite mode operations include operating full duplex and Doppler correction. http://aprs.org/psat.html If anyone has direct influence on any PSK31 authors, you might mention our needs for a Satellite mode that includes these features. PSAT has an estimated life of over 3 years. Although PSK31 operation is primary, we have plenty of power, so the APRS digipeater (only 300 mW) is also on full time. In addition, we have activated PSAT?s own APRS position reporting, and with its position knowledge, it also has unique Bulletins for each Continent. Take the positions with a grain-of-salt, however, since we have quirks in the onboard clock and have to frequently re-sync the clock to the real orbit. But we have ground stations in Maryland and Europe assisting in this. Your best PSK31 Uplink opportunity with least Doppler change (so everyone else can decode you) is the highest elevation pass while coming towards you and then away from you. You can see these stations in the waterfall with practically no Doppler change. Those uplink stations off to either side will have more and more changing Doppler during the pass. Its fun to watch the waterfall ad visualize what is going on.

Therefore the file contains an additional line with data for ; this tone frequency. To set this tone frequency with SatPC32 click the "T" ; control until it shows "T2". Then switch to TX for a few seconds. Click ; the "T" again until it shows "T1".

Apply, seek out audiences, win the opportunity. Here's my experience of some very enjoyable times. I applied for a SAREX contact about 20 years ago. We did the contact from the Local Planetarium I worked at...Dr Ron Parise WA4SIR was the astronaut we spoke to... http://www.arrl.org/news/ronald-a-parise-wa4sir-sk I remember it like yesterday. STS-67 was the shuttle mission. AOS brings the moment of truth, will the plan work ? It did for us...11 students asked their own question 10 heard answers before LOS. The backup equipment not needed that day. I think it was 10 scouts, if not 11, each got to ask a question twice. Audience of about 50 packed in a small auditorium. No YouTube in 2005 nor video camera in every pocket... Then, 2 years I was on the team that did the ARISS contact from K2BSA at the US National Scouting Jamboree. I had the privilege to call Maj. Luca Parmitano at AOS to establish the contact. The most tense moment of after about 2 years of work. The plan worked that day also. Audience of 100 outdoors that day. It's on YouTube. http://youtu.be/yzDNMetelH8 contact established at 4:00 in the video. I'm seated at the table. We worked every satellite pass for 7 days to ensure we had a good station. This is weak signal work. (It's not perfect) Paul AA4ZZ is standing by the table next to me. Also Ron Wood WA0BRO was instrumental in our sat station. We has a great team led by Jim K5ND (also on the video), I say this because you will enjoy the folks you share this passion with...and it takes a team. My application is in to go do it again in July 2017 I find this is highly addictive activity. Vast amounts of work and preparation with 1 chance for success (always in front of an audience), with amazing satisfaction / reward. Be encouraged to pursue more of this activity. There's great spirit in Amateur Radio to be enjoyed in the teamwork. While I describe this, I want to be careful to say, it's not about me. It's about the team, it's about providing the opportunity for students to talk to an astronaut via our hobby/passion, Amateur Radio. Now I feel like its time to say, Class dismissed.

Bob is very good on returning emails so let him know if you have any questions about his interesting system. In addition to CNCTRK there are a number of other portable rotors that have been around for a while (satnnogs,? WRAPS and http://www.mobypicture.com/user/MeltdownCore/view/18165109 to name a few). Has anyone built and used any of these relatively new lightweight portable rotors. If you have any first hand experience with one or know of any others please let me know direct and/or on the board. tnx & 73 W9KE Tom Doyle _______________________________________________ Sent via AMSAT-BB at amsat.org.

If you do get on, all you need to say is something like "N1EN EM55/45 grid line." You must be right on the line, a GPS showing that you are indeed at 90.0000 degrees West or a smartphone with a GPS app showing that would be adequate. I suppose a satellite image of the house from a site like ( http://no.nonsense.ee/qth/map.html ) and a picture of you standing right at a position where the line runs through would be adequate too in the unlikely event that the ARRL actually were to request documentation. LoTW supports up to four grids per QSL.

We probably shouldn?t be dogmatic about it, as that turns people off, but I think we should encourage all FM satellite ops to work towards operating full duplex. I suspect that the operable word in AA4KN?s article is ?adequate?. What may be adequate for getting the 100 extra FD points, is really not suitable for long term development of skilled satellite operators. I think the chaos one hears on the FM birds during FD is testimony enough to the meaning of adequate in this context. It is easy to work most of the FM birds, so easy that it can be done with half-duplex. Many never progress beyond that. But there are lots of advantages to full duplex: hearing your own signal, knowing its quality, hearing who else is on the bird, not stepping on them; learning to wait in turn to call DX and in short, knowing when to talk and when to shut up. Teaching full duplex is not hard; a second rig can be inexpensive these days and loaning one to a half duplex op who wants to go full duplex is on possibility of easing people into full duplex. When some one mentions they are having problems working the FM satellites, I always ask if they are working full duplex. Most of the problems that a novice has can be identified and easily remedied by themselves if they go to full-duplex. Another less obvious reason is that full duplex is almost mandatory on the linear satellites, and I think we should be trying to move newcomers from the FM birds to the linear birds. If they use Full-Duplex on the FM birds that is one less skill they have to learn when they go to the linear birds. The FM birds, while easy to work and loads of fun, offer only a fraction of the capabilities of which amateur radio communications are capable. But I suspect that I am preaching to the choir. - Duffey KK6MC On Jul 3, 2015, at 11:18 PM, Clint Bradford wrote: > I was startled reading AA4KN's proclamation in his July, 2015 QST article > that " ... a half-duplex rig will be adequate for the Fox satellites, but a "full > duplex" transceiver is even better ...

Anyone who read the full article can clearly see that Dave is NOT advocating using half duplex to communicate with FOX-1A. The full text of the excerpt reads "With a minimum power output of 400mW, Fox1A should be easy to work with an ordinary VHF/UHF FM handheld transceiver and a dual-band handheld Yagi antenna. Most VHF/UHF handhelds can only communicate in "half duplex." This means they cannot receive simultaneously while transmitting. A half-duplex rig ill be adequate for Fox satellites, but a "full duplex" transceiver is even better. A full duplex transceiver receives and transmits at the same time. This allows you to monitor the quality of your signal through the satellite so that you can make antenna and frequency adjustments as needed." As I read this it seems the author makes the statement as to why full duplex is superior and preferred over half duplex. A nice teachable moment for the newbie to understand that while FOX-1A and other FM satellites can in fact be worked half duplex it is best understand why full duplex is the preferred method. My first contacts were half duplex and I quickly learned that full duplex was not only preferred but is the acceptable way to communicate through any satellite. At the time I got started I was influenced by an article on the web titled "Work FM Satellites with your HT!" advocating that all I needed was a single handheld and a tape measure antenna. I notice that the article has been since updated to include "Ideally, we should be working the satellites in full duplex mode, where we can simultaneously listen to the downlink as we are transmitting." Thank you for clarifying this. However, I am confused, especially seeing this recent criticism, that the article just mentiend continues the previous sentence with " Although this method is preferred, it is not mandatory:" I commend Dave for his article and efforts to keep us all informed and educated. 73, EMike E.

Pure nonsense. From the article ... "Working Fox-1A" "With a minimum power output of 400mW, Fox-1A should be easy to work with an ordinary VHF/UHF handheld transceiver and a dual-band handheld Yagi antenna. Most VHF/UHF handhelds can only communicate in "half duplex." This means they cannot receive simultaneously while transmitting. A half- duplex rig will be adequate for the Fox satellites, but a "full duplex" transceiver is even better. A full duplex transceiver receives and transmits at the same time. This allows you to monitor the quality of your signal through the satellite so that you can make antenna and frequency adjustments as needed." My quotation of ... " ... a half-duplex rig will be adequate for the Fox satellites, but a "full duplex" transceiver is even better ... " ... captures the "essence" properly.

The 10M downlink doppler was easy to deal with and the 144 MHz uplink not much harder. The RS birds in particular had huge signals on the downlink, sensitive receivers, consistent 20+ minute passes, and could be heard with the gear most hams had; an HF transceiver. To get started, many hams used their 2M rig as a CW rig by keying the PTT. It sounded pretty chirpy, but those guys made a lot of contacts and generally graduated to a 2M CW or SSB rig. The problem in those days was getting the Mode A easysat guys to move up to Mode B or Mode J, with better performance. It is a problem very similar to what we have today of getting the FM easysat guys to move up to the linear birds. I have no problem with the entry level to satellite communication being easy. I do have problems when the entry level guys don?t move up, either because they are satisfied with the status quo, don?t get encouragement from experienced ops, or because the resources are not there. I don?t mean to denigrate Steve?s article, but rather to respond to Cliff?s comments and its implications. - Duffey KK6MC On Jul 4, 2015, at 11:19 AM, Joe wrote: > Funny how a linear bird is a technical challenge, wow, as a novice in 1975 I listened to Oscar 6 & 7 all the time. and once up graded used them also all the time.

With OSCAR 6 and 7 and their strong ten meter downlinks, it was just a matter of adding two meter transmit capability to an HF station. Now it does take a little more work to receive and transmit at VHF and UHF with SSB or CW and the prevalence of man-made noise on VHF and UHF these days generally requires a beam. I am quite certain that many of the people that worked OSCARs, 6, 7, 8, and the RS birds never graduated from Mode A. Just like many of the FM satellite users never graduate from FM. People tend to think it's more difficult than it is. I've made over 2,000 linear transponder contacts with nothing more than two Yaesu FT-817s (for a few hundred of those I used an Icom IC-R10 receiver) and an Arrow antenna handheld. The radios for operating via a linear transponder are widely available and inexpensive. A Yaesu FT-100, FT-817, FT-857, FT-897, FT-991 or an Icom IC-706MkII(g), Icom IC-7000, or any of those plus a FUNcube dongle and computer to receive the downlink are all the radio you need and an Arrow or Elk antenna will get you going. 73, Paul, N8HM On Sat, Jul 4, 2015 at 1:19 PM, Joe wrote: > Funny how a linear bird is a technical challenge, wow, as a novice in 1975 I > listened to Oscar 6 & 7 all the time. and once up graded used them also all > the time.

A simple low pass filter or diplexer on the output of the transmit radio should eliminate enough of the third harmonic to prevent desense.

Unfortunately, the quality control on the Baofeng assembly line is now what it should be. No two radios of the same Baofeng model will perform the same, every time. It is possible to use two UV-5Rs, two UV-82s, or a combination of UV-5R and UV-82 to work satellites. I've done this. I don't normally use this option, but did it so I could "walk the walk" when I say that it is possible to use two of these inexpensive radios - including at a hamfest demonstration I gave last year in southern Arizona: https://www.youtube.com/watch?v=_cLx9h-vNRA I used a UV-82 as the transmit radio, since it has a PTT that can key each VFO individually. The speaker-mic I use with the UV-82 also has separate PTT buttons. I put 145.850 MHz in both VFOs, and set the appropriate PL tones to activate the satellite (74.4 Hz) and to talk through the satellite (67.0 Hz) in each VFO. No need to change frequencies/memories on the transmit radio with this setup. I used a UV-5R as the receive radio, set to tune in 2.5 Hz I may have an advantage in working SO-50 with two of these HTs, since I use an Elk log periodic instead of an Arrow Yagi or equivalent homebrew dual-band Yagi. I have to use a diplexer to connect two radios to the single feedpoint on the Elk, so the diplexer is also serving as a bandpass filter. 73!

My belief is the uplink frequency choice was a mistake. Why mix terrestrial and satellite users on the same frequency? A nice quiet frequency in the OSCAR subband would have been a better choice, in my opinion. 73, Paul, N8HM On Sat, Jul 4, 2015 at 2:56 PM, Robert Bruninga wrote: > Segway this argument to the 10m uplink now 100% available on PSAT PSK-31 > which virtually no one is using. > >> With OSCAR 6 and 7... ten meter downlinks, it was just a matter of > adding two meter transmit capability to an HF station. > > For PSAT PSK31 it is even simpler.

Here's what I have done, based on what I learned from Patrick WD9EWK and John K8YSE among others. 1. If you are going to operate on a grid line, you are supposed to "prove it" according to the VUCC rules. Special attention is to be paid to section 4 (e) and 4 (f), which explain in detail that: * You have to be "present" in all grids. * You have to prove it with a GPS set to WGS84 (the default). * The GPS reading has to be mo more than 20 feet of error. * Get two photos: the GPS reading and the placement of the GPS in the operating setup. Here is a reference to those rules: https://www.arrl.org/files/file/Awards%20Application%20Forms/VUCCRULE1a.pdf Practically speaking, I park so that the back end of the minivan is right on the line and set up the radios right on the open back end. Take a big picture and a closeup, and we're good. If you go somewhere particularly rare, it is a good idea to take these pictures even if it's only for 1 grid square. 2. If you can, send a note to AMSAT-BB indicating when you will be operating and which passes. If you are on Twitter, post it there. I have posted even an hour ahead of time and it is always a good idea to get the word out. My notes look like this: > Subject: Impromptu Grid DXpedition: KL7CN/W6 at CN80 on SO-50 at 02:37Z with LotW Confirmation > > Hello, all: > > Sorry for the short notice -- we'll be active as follows: > > QTH: CN80 in Northern California > Satellite: SO-50 > Date and time: Today 2015-06-21 02:37Z > Confirmation: LotW, etc. > > -- bag > > Bryan KL7CN/W6 My Twitter posts are just the subject line. 3. When I call out I saw something like this: K-L-7-Charlie-November Slash Double-you Six Delta-Mike-Zero-Five/Zero-Six Gridline Keeps it short, and advertises that I am in a special place. I don't bother with signal reports. Everybody gets a 5-9 from the DX. When someone calls me, suppose it is N4UFO, I say something like this: November Four Uniform Foxtrot Oscar Confirm No need to retransmit the grid or my call. 4. If you can, record the pass. You will thank yourself later. 5. Ask W0DHB about LotW logging. He is an expert with LotW and HRD. The main detail is getting a proper location set up in LotW that includes both grids. It's not hard, but it is unusual so it's a good idea to take a little extra time and get some help to get it right. Sounds like fun! Go for it! -- bag Bryan KL7CN/W6 On Jul 4, 2015, at 06:53, Michael Adams wrote: Due to a death in the family, I am currently enroute to my parents' place in Memphis.

A correction.... the UV-5R I used in the YouTube video I referenced earlier was set to tune in 2.5 kHz steps, not 2.5 Hz steps. The Baofeng radios, like those from the other Chinese brands, tend to have sharper front-ends than the Icom/Yaesu/Kenwood amateur HTs. There will be moments where the UV-5R (and other Chinese-made radios) won't hear the SO-50 downlink, if you are tuning these radios in 5 kHz steps. When the time comes that we have Fox-1 FM satellites and EO-80, I don't think it will be necessary to tune the 70cm uplinks in 2.5 kHz steps. The 5 kHz steps would probably work fine, and this is something I'll try as these satellites become available for us to use. 73!

I knew the die was cast and all brakes were off. The XYL "situation" not withstanding. It took time but the "onward" trajectory was constatant-VHF/UHF Icom twins, manual everything. Now with a IC-910, 14 el CP on 2M, 40 el CP on 70cm. Yaesu G5500 az/el Everything computer controled. L and S band complete systems in moth balls. I still dig for the challenge that started everything. Being of the digitally challenged group it can be PITA. I consider my crowning achievement a fully functional capability system with AO-40 (sobsob). Should in the future we have the wherewithal (money) to get another or similar AO-10/13/40 up there. They will pour of out of the woodwork, (build it and they will come). Unfortunately we need the funds before the people. My potential lottery winnings are earmarked for that. Untill then my friends we must dig deep and pay what we can. Currently when time permits I will work everything up there, still learning the digital stuff (not easy). Like my friend Frank (K4FEG) says, "work-em till the antennas vaporize". The big party line we have with each other on the satellites is enjoyable and new ops are a special treat. We all approach this endeavor and some stop where they do for whatever reason. For the "brakes are off" people it's can be and is a hell of a fun ride. 73 Bob W7LRD Seattle-CN87 ----- Original Message ----- From: "Bill Dillon" To: amsat-bb at amsat.org Sent: Saturday, July 4, 2015 12:09:57 PM Subject: Re: [amsat-bb] Fox, "Easy Sats"....et al....

It?s a pain. I usually program in memories for AOS, AOS+, MID, MID+, and LOS. And, once in a while, I change the wrong channel or transmit on the wrong frequency. I?ve suggested a firmware change to everyone who will listen to offer a PTT selection and TUNE selection so the operator doesn?t have to toggle the A/B; but, so far, no success. If the D72A could also have smaller frequency steps and the ability to select which radio (A or B) was designated for PTT and for TUNE, the D72A would be a great HT for portable use. From what I?ve been able to determine, you cannot ?link? VHF and UHF memories together to achieve the split function you described. This would be another firmware option that could offer some convenience. I love the D72A, and, it?s a shame that to work the [flame off] Easy Sats, it?s easier to buy a $39 radio than to use a very full featured radio. Maybe if more folks agreed with the suggestion, Kenwood would listen. I would also like to see a new HT with a Bluetooth interface to allow for iOS or Android Apps which could remotely change the frequencies or channels during a pass. This could also allow for audio interfaces for PSK-31, APRS, Packet, and more. 73, Frank K5HS > On Jul 4, 2015, at 20:15, Philip Jenkins wrote: > > I bought a D72A a little over a year ago because it had APRS built-in; this > made it very handy for the balloon-chasing I used to do. > > Now I'm trying to set it up for SO-50.

It stemmed from a discussion with Keith Pugh, W5IU: I spent quite a bit of time with Keith Pugh, W5IU, of AMSAT, who also owns a D72A. We commiserated over the fact that the new radio doesn't allow for separate PTT and Tune of the A and B bands. We'd like to suggest that a future firmware update offer a RADIO MENU Option for PTT which would toggle through: NORMAL, A=PTT/B=TUNE, A=TUNE/B=PTT. The Band selected for TUNE would be flagged with the standard solid "arrowhead" and the Band selected for PTT would be flagged with a "flashing" "arrowhead". This would allow for easier use of the radio for LEO satellite work, especially when the download needs to be tuned. Right now, the operator needs to remember what Band is selected and ensure the correct Band is chosen before changing the frequency, either via VFO or Memory Channel. It's very easy to get confused and change the uplink frequency and, then, transmit on the downlink. Having separate PTT/TUNE would make this radio a lot more fun for satellite use. Maybe someone?s listening out there who could help. 73, Frank K5HS (ex KR1ZAN) > On Jul 4, 2015, at 20:42, Frank Krizan wrote: > > Hi Philip, > > I?ve just gotten used to pressing the A/B switch to toggle the PTT/Tune to the frequency I want to change.

I remember working the RS Birdsback in the '70's on Mode A with Inverted Vee's on 10 & 2M and trackingwith a TRS-80 and a freeware program. The Band was often loaded withusers on CW & SSB!! Mode K was a blast using 10M up and 15M down.The Ruskies made some excellent satellites!!!! ?Sorry that they're gone. 73, ? ?Bob K8BL From: Bob- W7LRD To: Bill Dillon Cc: amsat-bb at amsat.org Sent: Saturday, July 4, 2015 4:28 PM Subject: Re: [amsat-bb] Fox, "Easy Sats"....et al.... Greeting Satellite friends and a happy 4th -From the moment I worked either it was RS 12 or 13 with 15M up and 10M down with a Swan 350 and Drake R4A , over twenty years ago. I knew the die was cast and all brakes were off. The XYL "situation" not withstanding. It took time but the "onward" trajectory was constatant-VHF/UHF Icom twins, manual everything. Now with a IC-910, 14 el CP on 2M, 40 el CP on 70cm. Yaesu G5500 az/el Everything computer controled. L and S band complete systems in moth balls. I still dig for the challenge that started everything. Being of the digitally challenged group it can be PITA. I consider my crowning achievement a fully functional capability system with AO-40 (sobsob). Should in the future we have the wherewithal (money) to get another or similar AO-10/13/40 up there. They will pour of out of the woodwork, (build it and they will come). Unfortunately we need the funds before the people. My potential lottery winnings are earmarked for that. Untill then my friends we must dig deep and pay w hat we can. Currently when time permits I will work everything up there, still learning the digital stuff (not easy). Like my friend Frank (K4FEG) says, "work-em till the antennas vaporize". The big party line we have with each other on the satellites is enjoyable and new ops are a special treat. We all approach this endeavor and some stop where they do for whatever reason. For the "brakes are off" people it's can be and is a hell of a fun ride. 73 Bob W7LRD Seattle-CN87 ----- Original Message ----- From: "Bill Dillon" To: amsat-bb at amsat.org Sent: Saturday, July 4, 2015 12:09:57 PM Subject: Re: [amsat-bb] Fox, "Easy Sats"....et al....

This is going to be the plan for my upcoming road trip, starting on Thursday (9 July) and wrapping up on the following Monday (13 July). This includes an AMSAT presentation, some time in/around San Diego, and at least a thousand miles' driving. Here goes... Thursday (9 July) AM: drive to San Diego. Thursday PM: Work afternoon AO-7/FO-29/SO-50 passes from either DM12 or DM13, possibly both if there is any interest in both grids. Then an AMSAT/satellite presentation at Escondido Amateur Radio Society in DM13, including a possible demonstration before or after club meeting on AO-73. Friday (10 July): no radio until late in the day, possible DM04/DM05 activity on AO-73 @ Mojave CA in the evening. Saturday (11 July) AM: morning AO-7 or FO-29 passes from DM04/DM05 line @ Mojave CA, then 5-hour drive to Santa Cruz CA. If I'm making good time, I might stop in DM06 for 1 or 2 AO-73 passes on the way to Santa Cruz. Saturday PM: hoping to work afternoon AO-7/FO-29/SO-50 passes from CM86/CM96 line @ Santa Cruz CA. If not possible, work from one of the grids in the afternoon, then the other via AO-73 in the evening. (CM86 appears to be the rarer of these two grids) Sunday (12 July) AM: morning AO-7 or FO-29 passes from Santa Cruz CA (hoping for CM86/CM96 line, but probably just CM86 if I can't get on the line), then drive south - either along the coast on CA-1, or inland on US-101. I might be able to work from the CM95/CM96 line, if I'm not able to get CM96 on the air much from Santa Cruz, before going down to Santa Maria. Sunday PM: hoping to work afternoon AO-7/FO-29/SO-50 passes from CM94/CM95 line @ Santa Maria CA. Maybe eastern AO-73 pass in the evening as well. Monday (13 July): not sure if I will work passes before departing Santa Maria, but hoping to get through Los Angeles and make it to DM23/DM24 line north of Quartzsite AZ for afternoon AO-7 or FO-29 passes. Then a quick drive home. Weather conditions, especially the fires, might cause my plans to be altered. I'll use Twitter and posts to the -BB to make updates. 73!

From the Packet Section of the D72A Manual: "Note: * When the operating band is Band A, you cannot change to Full Duplex mode. * When in single band mode, and Band A/B is set to VHF/VHF or UHF/UHF, you cannot change to Full Duplex mode. * When using the Full Duplex function, connect an earphone to the SP jack. Using an earphone will prevent feedback that can cause the transceiver to emit a howling sound.? 73, Frank K5HS > On Jul 4, 2015, at 21:49, Philip Jenkins wrote: > > So, none of you has said a word about turning on the "duplex" feature at > all.....do I just need to forget about setting it, and just deal with the > dual VFOs? > > Thanks for the great suggestions I've gotten so far. :-) > > Philip N4HF > > On Sat, Jul 4, 2015 at 8:55 PM, Frank Krizan > wrote: > >> For Philip and the group, >> >> Here?s the suggestion that?s been floating around since 2011.

I'm sorry so many of you got offended at my view of the hobby but this duplex issue should have been put to bed long ago. BTW, my "snob elitist" station I'm putting back together will consist of my FT-991 which is my main rig and a Funcube Dongle Pro. Antennas will be WA5VJB "cheap yagis". I'm also working with someone to have gerbers made of my rotor control system schematic and if that doesn't work, I'll be riding the control of a TV rotator manually.

The good news is it still operating. The bad news is the power situation has been degrading, with an apparent step change on or near May 12, 2015, followed by another on Tuesday, June 23, 2015. The last full telemetry capture made here in EN82 land was on Wednesday, May 27, 2015, and the last time it was heard was on Friday, June 6, 2015. I continued to attempt to listen for it for another week or so, and heard nothing. Has anybody heard it since then? At this point, I have been monitoring it using Anton's (ZR6AIC) WebSDR as it makes daytime passes over South Africa. These occur between 7:30 and 9:00 UTC, which translates to 3:30 and 5:00 AM here in EN82 land. This is tough, as I am not a morning person. Sometimes, however, you have to do these things; helping build a satellite might be a once-in-a-lifetime event. During these passes, where it has already spent a significant amount of time in sunlight, the battery voltage is below 3400 mV. Is the battery going bad? While it is certainly possible the battery has suffered from some loss of charge capacity, one has to remember it is does not generate energy; it merely stores it. Since it is the solar power system that generates the power used by the satellite and stored in the battery, could the drop in battery voltage be due to a degradation in solar power generation? Back around May 12, I noticed the MPPT (solar) current readings were typically less than 10 mA. This much lower than it should be. To better understand what might be going on, a new chart was added to the telemetry spreadsheet which shows both the battery voltage and the MPPT (solar) current (with the zero readings removed), each with its own linear regression line. This chart can be seen from the following URL: https://www.dropbox.com/sh/l3919wtfiywk2gf/ AABKSR5V4cOvEPqPYbs8QYZNa/Telemetry-analysis/Current- Telemetry/Battery-Voltage-MPPT-Current-Chart.pdf Notice how the MPPT current trend line has been sloping downward, similar to that of the battery voltage. Moreover, starting 2 weeks before June 4, 2015 (each X axis division on the chart represents 2 weeks time), each reading has been at or below the trend line. A more striking comparison can be seen by doing the following: 1. Zoom in of the Battery-Voltage-MPPT-Current-Chart to show the 4 week interval starting May 7, 2015, and ending June 4, 2015 (see https://www.dropbox.com/sh/l3919wtfiywk2gf/ AACdQtySHZW3kVl7UMgSrxfHa/Telemetry-analysis/Battery-Voltage-MPPT- Current-Comparison-2015-05/Battery-Voltage-MPPT-Current-2015-05.pdf) 2. Zoom in of the Battery-Voltage-MPPT-Current-Chart to show the 4 week interval starting May 8, 2014, and ending June 5, 2014 (see https://www.dropbox.com/sh/l3919wtfiywk2gf/ AACracUWkivilfsKGBUFkmDXa/Telemetry-analysis/Battery-Voltage-MPPT- Current-Comparison-2015-05/Battery-Voltage-MPPT-Current-2014-05.pdf) [Editor's Note: The URLs above don't port well via tinyurl.com and have been truncated to fit the ANS format requirements. They should be copy and pasted as a continuous line to work with most browsers.] In comparing these charts, it is clear both the battery voltage and the MPPT current were significantly lower this year that during the same period last year. On June 5, 2014, the trend line value for battery voltage was about 3610 mV, and for MPPT current was about 30 mA. One year later (June 4, 2015), the trend line value for battery voltage was about 3380 mV, and for MMPT current was about 14 mA. Therefore, while it is likely the battery has suffered some loss of capacity, it appears the low battery voltage is due to low solar power output. There are many possible reasons for this, including: * Solar cell damage due to sputtering: since there was no protective covering on the solar cells, impacts from high energy particles can damage the cells, causing a drop in output. * Solar cell damage due to thermal cycling: We know from telemetry data the interior of the satellite cycle between +30 degrees C and - 30 degrees C each orbit. It is likely the exterior temperatures experienced higher extremes, and this periodic thermal cycling may have caused the solar cells to fracture, thus leading to a drop in output. * Short circuit failure of one or more of the diodes which isolate each MPP tracker output, which can cause an inactive MPP tracker (one whose corresponding solar panel is not facing the sun) to load an active one (one whose corresponding solar panel is facing the sun). Because of the limited amount of telemetry gathered, it may not be possible to determine the exact cause. If the solar output power continues to drop, the battery voltage may never get above the 3300 mV threshold needed to enable the transmitter, at which point we will lose the ability to monitor its status. Even if this does happen, however, we never really thought it would last this long. We would have been happy if it just worked, and really happy if it lasted a month or two. 19 months - this is way beyond what any of us expected! As of June 25, 2015, the orbit has decayed by about 73 km since launch. Since April 21, 2015, it has been decaying at a rate of about 1 km per week. Apogee is now at 561 km, and perigee is at 529 km. The following are the TLEs from 2015-06-25: EAGLE 2 1 39436U 13066W 15176.16386703 .00013608 00000-0 90105-3 0 9991 2 39436 97.7444 252.3622 0022818 80.2035 280.1767 15.07230510 86697 Again, if anyone wants to make an attempt at predicting when it will de-orbit, here is some useful information: Average cross-sectional area = 0.014252 m^2 Mass = 210 g Area/mass ratio = 0.06787 m^2/kg >From the 2015-06-25 TLEs: Semi-major axis: 6922.8 km Eccentricity: 0.0022818 Apogee: 560.6 Perigee: 529.0 As always, please post any telemetry, or for that matter, any reception reports to the Yahoo discussion group. We would especially like to encourage our friends in the southern hemisphere to listen for $50SAT/MO-76/Eagle-2. We really appreciate everyone who has provided reception reports and telemetry as well as access to their WebSDRs. To date, we have 3,098 individual error-free telemetry captures, and the vast majority of these did not come from Stuart, Howie, or I. 73 Michael Kirkhart KD8QBA $50SAT/MO-76/Eagle-2 team $50SAT is one of the smallest amateur radio satellites ever launched at 5x5x7.5 cm and weighs only 210 grams. Transmitter power is just 100 mW on 437.505 MHz (+/-9 kHz Doppler shift) FM CW/RTTY. It uses the low cost Hope RFM22B single chip radio and PICaxe 40X2 processor. $50SAT has been a collaborative education project between Professor Bob Twiggs, KE6QMD, Morehead State University and three other radio amateurs, Howie DeFelice, AB2S, Michael Kirkhart, KD8QBA, and Stuart Robinson, GW7HPW.

After that presentation, and after spending the next day (Friday, 10 July) in and around San Diego, he will head north. Other than a planned stop at the DM04/DM05 grid boundary north of Los Angeles (the same spot he stopped at last September, near Mojave CA and Edwards AFB), He may be going to head further north. He hopes to have some time to go either north through the San Joaquin Valley, or over to the Pacific coast, or some sort of loop to see a lot more of central California. Whereas there is not a set itinerary for the portion of his trip after the DM04/DM05 stop, he has asked other satellite operators via Twitter for feedback on some grids that would make for worthwhile visits during his trip. Patrick is asking for feedback, "If I look to go up or down the Pacific coast, grids I could visit include CM94 through CM96, and possibly even as far north as Santa Cruz and the almost-all-wet grid CM86. If I stay inland, DM0x grids would be where I'd probably drive through. I'm not planning to go all the way up to the Bay Area, although Santa Cruz is not that far from San Jose. Any thoughts from the crowd here, on grids that I should try to visit between 11 and 13 July?" On his return trek to Phoenix on 13 July, he could be able to make a stop on the DM23/DM24 boundary, either north of Quartzsite on the Arizona side of the Colorado River, or just across the river along US- 95 in California. This stop will depend on whether or not a satellite pass is available as he passes through that area. Patrick notes that he won't be passing that way on his trip out to San Diego. During his travels he will be running APRS using WD9EWK-9, which should be visible on sites like http://aprs.fi/WD9EWK-9 . Check his twitter feed, @WD9EWK, for updates. Any QSOs made will be uploaded to Logbook of the World.

This position is now open due to the expansion of opportunities in the User Services Department. Our current editor, JoAnne Maenpaa, K9JKM, is also the Vice President of User Services. The Officers and the Board have discovered that it is impossible for a single volunteer to accomplish management of the AMSAT Journal with the other pending User Services leadership requirements. Hence we are planning on a handover in editorship when a suitable candidate is found. Experience with the Adobe InDesign CS6 publication system would be helpful (AMSAT provides the software). However, this publishing system resembles a word processor on steroids; while there is a learning curve it will not be impossible.

Contact was established at about 18.50 UTC via ARISS ground station W6SRJ in Santa Rosa, CA, USA. Though the signal from the ISS was strong and clear, a delayed start for the interview meant that there was time for four questions for the Russian cosmonaut. Responding to one of the questions during the interview that was conducted in English, the Russian crew member explained that the temperature outside the ISS varies between +120? and -120? Celsius. School Information: We are a technical university located in Temuco city, 700 kms south of Santiago de Chile and we are planning this event together with telecommunications engineering area. Our university has direct contact with local schools which will be taking part on the event that day. We are planning to invite around 400-500 students because we will organize an open science fair called "telecommunications and space" and we will be teaching them radio communications, antennas and space science along with professional astronomers and engineers. The children will be from five or six different schools located in Temuco and surrounding rural areas. We will coordinate with the schools to select the students and ask their own questions. Upcoming ARISS Contact Schedule + A direct contact with students at Tulsa Community College, Northeast Campus,Tulsa, Oklahoma, USA was successful Wed 2015-07-01 15:59:17 UTC 20 deg. Students ranging in age from 60 to 13 asked cosmonaut Gennady Pedalka, RN3DT thirteen questions. The interview included a question from a deaf engineering student that was managed through an interpreter. Preparing for the contact, students assembled the ground station that was used to make the contact and participated in an antenna design contest. Students tested their antennas by hand tracking the ISS. They practiced doing receiving tests with the assembled ground station prior to the day of the contact to sharpen their skills. A video recording of the contact is available at: https://www.youtube.com/watch?v=TZVWkPPLCEM&feature=youtu.be School information: TCC is Oklahoma?s largest community college with more students and more degree earners than any other community college in the state. We offer students a choice of 235 associate degree and certificate of completion programs of study. TCC students come from every walk of life, and our graduates work in all sectors of business and industry to help build a stronger, more diverse economy. Four campuses (Metro, NE, SE, and W) serve the Tulsa, Oklahoma area. If you're passionate about electronics, criminal justice, horticulture, engineering, computer networking, human services, fire emergency services, interpreter education or aviation science, "Northeast" is the campus for you. Located near Tulsa's industrial and aerospace hub, the campus is perfect if you're seeking a career in high-tech business or service-focused careers. Along with a strong educational curriculum, the campus is home to the Resource Center for the Deaf and Hard of Hearing, offering access to higher education for all segments of the population. The TCC Electronics club started in the early 1980?s on the NE Campus which is where the Electronics and Engineering Technology classes are offered. Amateur Radio activities were added in 2000 (the year an instructor came on board as the only HAM operator), and we became an ?ARRL? affiliated club in 2005. Now the TCC-ARC station consists of two towers for HF and VHF, along with two EME and Radio Astronomy arrays. Upcoming Contacts A direct contact with students at Kopernik Observatory, Vestal, NY, USA is planned for the week of July 6. More details will be provided when the schedule is confirmed at www.ariss.org. >From 2015-06-11 to 2015-07-24, there will be no US Operational Segment (USOS) hams on board ISS. So any school contacts during this period will be conducted by the ARISS Russia team.

Here's what I have done, based on what I learned from Patrick WD9EWK and John K8YSE among others. 1. If you are going to operate on a grid line, you are supposed to "prove it" according to the VUCC rules. Special attention is to be paid to section 4 (e) and 4 (f), which explain in detail that: * You have to be "present" in all grids. * You have to prove it with a GPS set to WGS84 (the default). * The GPS reading has to be mo more than 20 feet of error. * Get two photos: the GPS reading and the placement of the GPS in the operating setup. Here is a reference to those rules: https://www.arrl.org/files/file/Awards%20Application%20Forms/VUCCRULE1a.pdf Practically speaking, I park so that the back end of the minivan is right on the line and set up the radios right on the open back end. Take a big picture and a closeup, and we're good. If you go somewhere particularly rare, it is a good idea to take these pictures even if it's only for 1 grid square. 2. If you can, send a note to AMSAT-BB indicating when you will be operating and which passes. If you are on Twitter, post it there. I have posted even an hour ahead of time and it is always a good idea to get the word out. My notes look like this: > Subject: Impromptu Grid DXpedition: KL7CN/W6 at CN80 on SO-50 at 02:37Z with LotW Confirmation > > Hello, all: > > Sorry for the short notice -- we'll be active as follows: > > QTH: CN80 in Northern California > Satellite: SO-50 > Date and time: Today 2015-06-21 02:37Z > Confirmation: LotW, etc. > > -- bag > > Bryan KL7CN/W6 My Twitter posts are just the subject line. 3. When I call out I saw something like this: K-L-7-Charlie-November Slash Double-you Six Delta-Mike-Zero-Five/Zero-Six Gridline Keeps it short, and advertises that I am in a special place. I don't bother with signal reports. Everybody gets a 5-9 from the DX. When someone calls me, suppose it is N4UFO, I say something like this: November Four Uniform Foxtrot Oscar Confirm No need to retransmit the grid or my call. 4. If you can, record the pass. You will thank yourself later. 5. Ask W0DHB about LotW logging. He is an expert with LotW and HRD. The main detail is getting a proper location set up in LotW that includes both grids. It's not hard, but it is unusual so it's a good idea to take a little extra time and get some help to get it right. Sounds like fun! Go for it! -- bag Bryan KL7CN/W6 On Jul 4, 2015, at 06:53, Michael Adams wrote: Due to a death in the family, I am currently enroute to my parents' place in Memphis.

I did successfully use two radios a couple of years ago (which got much easier after I learned I didn't have to adjust the 2M uplink as well as the downlink), and I thought it would just be easier to have it all in one radio package. I was hoping the D72 would be more hands-free, but it still looks like I need at least 3 hands (one for the Arrow antenna, one to change frequencies on the radio, and another for the PTT switch on the headset :-) ) It sounds like EO-80 will be TOO easy to operate through, other than manually moving the antenna. :-) Thanks again for all the advice, both on the BB and personal emails.

Howdy, There also is the 1990's era Internet Relay Chat (IRC). It is mostly text based ascii characters without a lot of pictures. You need an IRC client to access this network, but it is free and open to the public. Chatzilla is an IRC plug-in for Firefox. mIRC is one of the stand alone IRC chat clients. Afficionados of IRC could point us to several other chat clients. There is a mostly idle, but still available AMSAT chat on the servers named radiochat.org: You'll need to tell your IRC client: /server irc.radiochat.org /join #amsat The Houston AMSAT net on Tuesday evenings is pretty much the sole remaining user on this AMSAT IRC chat. It is one of their ways of getting remote checkins to the net if you are out of range of the Houston repeater but have internet access. When the flocks of cubesats get launched the university teams and amateur satellite operators congregate on the #cubesat chat channel: /server irc.freenode.org /join #cubesat If Internet Relay Chat is new for you just google and find a few dozen pages of how to do IRC. I'm not sure if a phone app exists for IRC; I think when IRC was invented touch tone phones were new ;-) ... but it still works! -- 73 de JoAnne K9JKM k9jkm at amsat.org AMSAT VP User Services From ks1g04 at gmail.com Sun Jul 5 18:25:43 2015 From: ks1g04 at gmail.com (Stephan Greene) Date: Sun, 5 Jul 2015 14:25:43 -0400 Subject: [amsat-bb] Adding NO-84 PSAT to Gpredict Message-ID: Trying out ham radio packages on a Raspberry PI 2 (which is a nice piece of kit, particularly with the new "official" case .

Another thing that's handy for the TH-d72 is the M>V key. Put the center freq in memory, but before the pass copy it into the VFO for Doppler tuning. Saves having a lot of memories used for Doppler shift and the TX frequency isn't as likely to need big adjustments thanks to the capture effect on the satellite receiver.

Wasn't an issue for me before - I usually run > SatPC32 and "it just works". First, which version of Gpredict are you using? Second, what's your OS? If you're using Linux, look for a hidden directory in your account with the format: ./configure/gpredict This may vary between distributions and may have a different name, but directory won't appear on your desktop. You'll find it using: ls -al /home/xxxxx/Desktop where xxxxx is your account name. That directory will have some subdirectories. The ones you'd be interested in are satdata (which contains the TLE files) and tsrp (which have the frequency data). The TLE files are of the form NORAD-ID.sat and the frequency files are NORAD-ID.tsrp. Those are text files which can be edited and copied, but they need to have the correct NORAD ID number as their name. Once you've copied them, you'll have to log out and log in again in order for Gpredict to find them. After that, you can configure Gpredict to display the new satellites. Just a word of caution: you may have to do this a few times before it works, or at least I had to do it on my machine. I suggest you copy some existing files onto your desktop, edit them for the new birds, and then copy them into the correct directories. 73s Bernhard VA6BMJ @ DO33FL From wa4sca at gmail.com Sun Jul 5 19:17:38 2015 From: wa4sca at gmail.com (Alan) Date: Sun, 5 Jul 2015 14:17:38 -0500 Subject: [amsat-bb] Adding NO-84 PSAT to Gpredict In-Reply-To: References: Message-ID: <000201d0b757$4228c3f0$c67a4bd0$@GMAIL.COM> Steve, There is a law/regulation which covers launches with military or other classified payloads. (Somebody have the exact reference?) It prevents releasing the Keps in the normal way for the secondary payloads, so they have to come indirectly from the people who own the individual satellites. For instance, you can find all the other Keps from that launch here: http://mstl.atl.calpoly.edu/~ops/ultrasat/ultrasat_jspoc.txt It is updated every couple of days, instead of the 3-4 times a day we are used to. You need to match the actual names with the satellite and object number, or get them with the weekly updates to NASA.ALL. 73s, Alan WA4SCA From va6bmj at gmail.com Sun Jul 5 19:32:48 2015 From: va6bmj at gmail.com (B J) Date: Sun, 5 Jul 2015 19:32:48 +0000 Subject: [amsat-bb] Possible Clue To Last Week's SpaceX Failure Message-ID: http://www.spaceflightinsider.com/organizations/space-exploration-technologies/2014-incident-may-provide-clue-to-cause-of-spacex-falcon-9-failure/ 73s Bernhard VA6BMJ @ DO33FL From va6bmj at gmail.com Sun Jul 5 19:35:54 2015 From: va6bmj at gmail.com (B J) Date: Sun, 5 Jul 2015 19:35:54 +0000 Subject: [amsat-bb] New Horizons Anomaly Message-ID: http://www.parabolicarc.com/2015/07/04/horizons-enters-safe-mode/ http://www.spaceflightinsider.com/press-releases/new-horizons-team-responds-spacecraft-anomaly/ http://www.spacepolicyonline.com/news/nasa-establishes-anomaly-board-to-diagnose-problem-on-pluto-mission 73s Bernhard VA6BMJ @ DO33FL From va6bmj at gmail.com Sun Jul 5 19:37:33 2015 From: va6bmj at gmail.com (B J) Date: Sun, 5 Jul 2015 19:37:33 +0000 Subject: [amsat-bb] Progress Spacecraft Now At ISS Message-ID: http://www.parabolicarc.com/2015/07/05/progress-resupply-ship-arrives-space-station/ http://www.spacepolicyonline.com/news/russian-cargo-ship-arrives-at-iss 73s Bernhard VA6BMJ @ DO33FL From bryan at kl7cn.net Sun Jul 5 19:52:31 2015 From: bryan at kl7cn.net (Bryan Green) Date: Sun, 5 Jul 2015 12:52:31 -0700 Subject: [amsat-bb] Chat Room?

As far as I can tell, my packets did not make the double hop from Arizona through the ISS and NO-84. I could easily reach the ISS, and was able to exchange messages with K7TRK & N7NEV. I also saw Robert KO6TZ trying the double hop as well. I know NO-84 responds to ARISS in the UNPROTO path, as I saw that in action last weekend during Field Day and yesterday when I tried to go through only NO-84. I had been using RS0ISS, APRSAT based on a post by WB4APR recently. Had I used RS0ISS, ARISS as my UNPROTO path, would the ISS key on ARISS being in the path, or would it have used RS0ISS being the first item in the path, leaving ARISS untouched for the next station (NO-84) to use? I want to keep an eye out on this, and give it another try sometime. I missed out on the best chances to do this with the ISS and NO-44 earlier this year, although I enjoyed using NO-44 to make QSOs when it was in more sunlight. I doubt I'll try this test while I'm on the road later this week, but it is something I will try after the trip with the ISS and NO-84 - if I see passes line up like these two did today. 73!

Most of what I know about this comes from some of our past conversations. But ... When I first applied (in 2005) for our authorization to re-distribute the KEPs (in TLE format), I had a conversation with the then officer-in-charge of approving the TLE re-distribution authorizations at Air Force Space Command. He said exactly what you said, "There is a law/regulation which covers launches with military or other classified payloads." He did not elaborate any further and I got the feeling that he did not what to answer further questions on that subject. I (and anyone else who is not the owner/operator) cannot go into SpaceTrack and directly download the TLEs from SpaceTrack for satellites launched on a military launch vehicle. It is obvious that the owner/operator of the satellite can obtain the current TLEs, so for now, we get them from that entity. It is an extra step, but it can be done. Once we acquire the TLEs from the owner/operator, we are free to re-distribute as needed. I am sure that the owner/operator of a satellite on a military launch has a similar agreement that AMSAT has with SpaceTrack. Once AMSAT downloads the TLE data from SpaceTrack and puts the TLEs in our format, it becomes AMSAT's product. AMSAT (and anyone else that AMSAT sends it to) are free to send that data to anyone else. At AMSAT we do ask those re-distributing KEP data from AMSAT to leave the headers in place, thus giving AMSAT credit as the primary re-distributing data source. I hope this helps.

(Somebody have the exact reference?) It prevents releasing the Keps in the normal way for the secondary payloads, so they have to come indirectly from the people who own the individual satellites. For instance, you can find all the other Keps from that launch here: http://mstl.atl.calpoly.edu/~ops/ultrasat/ultrasat_jspoc.txt It is updated every couple of days, instead of the 3-4 times a day we are used to.

I think Gpredict tries to load anything it finds in the local file directory you tell it to use, as long as it's ascii and looks like keplerian elements. Bernard - running GPredict 1.13 on Raspbian Wheezy. Installed via apt-get, so there is also a collection of stock config files in /usr/share/gpredict. For other RPi users, if using the GUI that installs with Raspbian, it has a setting to view the hidden directories, which may make working with your specific configuration a bit easier vs. command line. The Debian dpkg tool can also list files used by gpredict and where they are installed. Alan - thanks for the reminder - I recall now the discussion following the launch why there were no keps at Celestrack. When I went back to celestrack and searched by NORAD ID, it shows the elements are not available. I am impressed with the increased computing power in the Pi 2 - running the GUI, Gpredict, and Direwolf (using a USB dongle for sound and another system to display the APRS traffic) runs smoothly. 73 Steve KS1G ks1g at amsat.org From va6bmj at gmail.com Mon Jul 6 04:42:35 2015 From: va6bmj at gmail.com (B J) Date: Mon, 6 Jul 2015 04:42:35 +0000 Subject: [amsat-bb] Adding NO-84 PSAT to Gpredict In-Reply-To: References: <000201d0b757$4228c3f0$c67a4bd0$@GMAIL.COM> Message-ID: On 7/6/15, Stephan Greene wrote: > Thanks to everyone who replied - I downloaded the keps file from Amsat and > loaded them from local file.

I haven't been able to install files for the newer birds directly from the Internet. I'm not sure if it's because of a bug in Gpredict. As a result, I've installed the files for the new satellites by hand as I described with little problem, on the whole. 73s Bernhard VA6BMJ @ DO33FL From va6bmj at gmail.com Mon Jul 6 04:45:07 2015 From: va6bmj at gmail.com (B J) Date: Mon, 6 Jul 2015 04:45:07 +0000 Subject: [amsat-bb] New Horizons Scheduled To Resume Normal Operations Message-ID: http://www.parabolicarc.com/2015/07/05/horizons-set-return-normal-operations-tuesday/ http://www.spaceflightinsider.com/missions/new-horizons-team-planning-on-resuming-science-on-july-7/ http://www.spacepolicyonline.com/news/pluto-mission-to-resume-normal-operations-on-july-7 73s Bernhard VA6BMJ @ DO33FL From va6bmj at gmail.com Mon Jul 6 04:47:15 2015 From: va6bmj at gmail.com (B J) Date: Mon, 6 Jul 2015 04:47:15 +0000 Subject: [amsat-bb] Preliminary SpaceX Conclusions Pending Message-ID: http://www.spacepolicyonline.com/news/musk-preliminary-conclusion-expected-by-end-of-week 73s Bernhard VA6BMJ @ DO33FL From wa4hfn at comcast.net Mon Jul 6 15:06:00 2015 From: wa4hfn at comcast.net (wa4hfn at comcast.net) Date: Mon, 6 Jul 2015 15:06:00 +0000 (UTC) Subject: [amsat-bb] Fwd: Satellite Communications the easy way In-Reply-To: <0d5cdae05233f79e11025a75d3ac2e90269.20150706145942@mail53.atl11.rsgsv.net> References: <0d5cdae05233f79e11025a75d3ac2e90269.20150706145942@mail53.atl11.rsgsv.net> Message-ID: <99933637.9950406.1436195160778.JavaMail.zimbra@comcast.net> ----- Forwarded Message ----- From: "W5KUB.com" To: "Damon" Sent: Monday, July 6, 2015 10:00:55 AM Subject: Satellite Communications the easy way Clint Bradford, K6LCS ** Amateur Radio Roundtable ------------------------------------------------------------ ** Subject: Satellite Communications the easy way ------------------------------------------------------------ It's time for Amateur Radio Roundtable, a live weekly amateur radio webcast and simulcasted shortwave program every Tuesday night at 8 PM CDT (0100 UTC Wednesday). The show can viewed at W5KUB.com (http://w5kub.us10.list-manage.com/track/click?u=0d5cdae05233f79e11025a75d&id=77d5fc3d40&e=3ac2e90269) or heard on shortwave radio station, WTWW on 5085 KHz. Tom Medlin, W5KUB, is joined by co-host Ted Randall, WB8PUM, from the QSO Radio Show. The show covers a wide range of topics for ham radio operators, shortwave listeners, and electronic hobbyists; including balloon launches, Satellite, go-kits, emergency communications, SDR, digital modes, DXing, home brewing, and more. During last week's show, there was a major U.S. internet routing problem and outage which affected our show. Due to this outage we were unable to proceed our show and it has been rescheduled for Tuesday, July 6th. This week?s guest will be Clint Bradford, K6LCS. Clint lives in Southern California, and, by last count, has performed his "How to Work Amateur Radio Satellites With Your HT" presentation almost 80 times at conventions and clubs across the United States. To learn working the "birds" with just a simple HT, tune in Tuesday night's show. Clint will also discuss other tools needed; such as, free tracking software, how to home-brew a simple Yagi antenna for more punch in the signal, and the simple protocol used when making these fun and interesting contacts. In addition to learning about the satellites, the same equipment is used to contact the International Space Station. Clint also coordinated a school contact with the International Space Station - enabling students to interview an astronaut as the International Space Station streaked overhead. Clint's websites are work-sat.com (http://w5kub.us10.list-manage.com/track/click?u=0d5cdae05233f79e11025a75d&id=ab4afb687f&e=3ac2e90269) and K6LCS.com (http://w5kub.us10.list-manage2.com/track/click?u=0d5cdae05233f79e11025a75d&id=a790f62dfd&e=3ac2e90269) We are adding a segment to the show at allows our viewers and listeners to call in to a phone line and be on the show.

The hand held devices have taken over their lives to a point that nothing else matters. Hobbies/life now are based on the handheld device so big rigs of the past are a thing of the past. Computers have gone the same way. If you check with a lot of other hobbies they are going away as well. Lately I am following a friend of mine who has a large HO guage train setup. He is selling it all off since he sees no younger group coming along to teach. Myself I am selling off most radio/electronic gear while there may be money in it.

Unfortunately the IP address will change, so server settings in RASCAL need to be updated. The transition will take place during the 8th of July. On this day both servers will not be offline for 4 -8 hours to be able to migrate the databases. The local repository of the RASCAL telemetry client frames should be sufficient to avoid data loss for the downtime. Our advice is to add the new server as primary/secondary server before the 8th and remove the old server after the 8th of July. New IP: 131.180.122.144 Port: 1099 In case plans change or things do not go as expected, we will notify you as soon as possible. Delfi-C3 is doing great. We have long exceeded the design lifetime of the satellite and she continues to work great. We appreciate your help in acquiring data of Delfi-C3 and hope that you continue to track our ?old? bird in the future as well!

I see Spaceflightnow.com have announced a delay to the amateur satellites initially due to fly on the 20th July I was searching around for the up and downlink frequencies for the transponder, but instead found this: Long March 6 ? Multi-payload Launch time: TBD Launch site: Taiyuan, China A Chinese Long March 6 rocket will launch with a cluster of small Chinese amateur and university research satellites. The flight will mark the first launch of the Long March 6, a new rocket fueled by kerosene and liquid oxygen to replace China?s previous generation of launch vehicles. Delayed from July 20.

Thanks for the antenna info. Bob, WB4APR *----- original message ---------* UP-Date, Excited now! Tried Rubber ducky inside,,, Nothing Rubber ducky outside, nothing 1/4 wave 2 meter GP but on the 70 cm freq inside, squelch breaks. 1/4 wave 2 meter GP but on the 70 cm freq outside started hearing it 2 min into the pass, had to use doppler 5 hogh for a while then spot on then later 5 low. heard at least two stations in there and I'm guessing the telemetry? it is a quite low tone in there. but even with that heard it pretty well. I may make a simple antenna that is more or less omni. and add the arr pre amp, got any plans for such an antenna?

Bob, WB4APR > If the robot is around 300 Hz above 28.120 then it is probably a propnet station. Could see if propnet authors are willing to make a sat version that will include dopler correction and sat prediction so they only transmit when the sat is in view. 73 de Andre PE1RDW From kk5do at arrl.net Thu Jul 9 01:17:15 2015 From: kk5do at arrl.net (Bruce) Date: Wed, 8 Jul 2015 20:17:15 -0500 Subject: [amsat-bb] Field Day Submissions Message-ID: <559DCB9B.4040802@arrl.net> For those of you that only worked one or two stations on the satellite or if you worked 10, 20, 50 or more stations, please still submit your scores for Field Day. Although the form online at http://www.amsat.org (click on the Events tab and then the Field Day link) is in PDF format, you can copy and paste the submission portion into Word (amazing how they migrate back and forth). Or you can download the DOCX file from me at http://www.amsatnet.com/fd2015.docx Please remember that ARRL submissions are due much later than our submission date. I must have your submission received by 11:59 PM Central Time on July 13, 2015 (Monday). I then have less than a week to tabulate and write the article for the journal. Please include any pictures that will show off your field day site. We have had flamingos, long horn steers, clocks running on lemons, campers, ladder towers and all kinds of neat stuff in the past. I will confirm that I have received your submission, usually sometime that day. If you do not hear from me, please send to my other email address, or send to both at the same time. kk5do at arrl.net kk5do at amsat.org 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards 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 g.shirville at btinternet.com Thu Jul 9 12:57:26 2015 From: g.shirville at btinternet.com (Graham Shirville) Date: Thu, 9 Jul 2015 13:57:26 +0100 Subject: [amsat-bb] Fw: DeorbitSail Details go online!

We still do have some minor issues to sort out: - Database performance seems slow. This won't affect the telemetry submission, but makes processing more difficult - We can at this time not create new user accounts. Please use the guest account until we can create the accounts. We will send account details as soon as they are created.

I am not bringing all my usual gear -- just FM. Listen for me on daytime SO-50 passes if you need any of those grids. I have operated from many of these grids a dozen times and I'll be back again so don't worry if this trip doesn't fit into your schedule. 73 Clayton W5PFG From rick at vk6xlr.net Sat Jul 11 03:06:08 2015 From: rick at vk6xlr.net (Rick Kowalewski) Date: Sat, 11 Jul 2015 11:06:08 +0800 Subject: [amsat-bb] DEORBITSAT Heard In-Reply-To: <1645a2.2da1fc39.42d1a8ad@aol.com> References: <1645a2.2da1fc39.42d1a8ad@aol.com> Message-ID: <55A08820.1080006@vk6xlr.net> Hi All, DEORBITSAT heard in Perth Western Australia (VK6) on 145.975 +/- during the 11 July 0300z pass.

Message-ID: <55A13881.7050102@denstarfarm.us> Before I give up and sell any Sat gear I have, I thought I'd ask if there is anyone USING an IC910H, SatPC32 and also reading/logging the UpLink and DownLink frequencies with DxLabs Commander. For many. many months I have wasted countless hours trying to get that combination to work together. SatPc32 with flawlessly control the rotors and the IC910H. DxLabs Suite Commander will pretty-well control the IC910H. If I try to use VSP Manager or Virtual Serial Port emulator to allow both controlling programs to use the IC910H, it simply will not function. Thus if I want to work the Sats, after each QSO I have to write down the uplink and downlink QRG , times, and such, so I can later log the QSO by typing it into the computer. It's a bit overwhelming to log when I often get a few calls for a semi-rare State, Kentucky. I seriously could use some help to set these programs to make the IC910H play the game. thanks (hopefully) 73, -- Bob KD7YZ http://www.qrz.com/db/kd7yz AMSAT LM#901 From pe0sat at vgnet.nl Sat Jul 11 16:45:58 2015 From: pe0sat at vgnet.nl (PE0SAT | Amateur Radio) Date: Sat, 11 Jul 2015 18:45:58 +0200 Subject: [amsat-bb] =?utf-8?q?BPSK_demodulators=3F?= In-Reply-To: References: <1436630658.19950.YahooMailAndroidMobile@web121004.mail.ne1.yahoo.com> Message-ID: Hi Edson, You won't regret it, it is a superb sound-modem and also has the ability to serve as a AGW and/or kiss server.

My only thoughts are: 1) You may lose some power through the duplexer. I recall they can be quite lossy. 2) The desense on UHF may be 3rd harmonic. In which case the duplexer or a low pass filter will be OK in the 2m side. But.. 3) The 'desense' may be due to the UHF radio input being unfiltered...In which case it is 2m overload. In that case you need a high pass filter on the UHF radio input. I really hope it isn't the same as my ICOM 706G which transmits phase noise everywhere. - No cure for that ! Good luck.

The beautiful coin will be a keepsake to treasure. The ARISS program relies on resource support from NASA, ARRL, AMSAT, and individual donors to ensure continuing the day-to-day operations and communications, and to pay for space-flight certification of equipment. Current finances to sustain operations in future years are insufficient. The ARISS program is initiating a fundraising campaign with the goal of securing greater financial stability for the program. According to ARISS International Chair Frank Bauer, KA3HDO, ?To assure the future of the program we are looking to individuals and corporate sponsors to provide the resources we will need to sustain operations and to acquire needed equipment upgrades.? Plans are underway to develop a new higher power Amateur Radio station for the ISS Columbus module. The current radio is a lower power unit that sometimes results in weak signals. A new radio system will improve the communications for education groups whose students are scheduled for ARISS contacts and related educational activities. The new system will also allow greater interoperability between the Columbus Module and the Russian Service Module. Integration of the equipment into the ISS infrastructure and required testing and certification require hours of engineering resources that ARISS must pay for and cannot afford. Each ARISS contact offers the opportunity to inspire young people through ARISS? unique window into space exploration activities, opening the horizon of possibilities of a career in a STEM field. Each contact also introduces students and their communities to Amateur Radio?all positives for Amateur Radio and our country and world. ARISS needs your help to secure these opportunities for the future. Individuals may make donations to ARISS online at www.amsat.org by selecting the ?Donate ARISS? button. (AMSAT-NA will provide people resources to handle your gifts to ARISS.) Individuals contributing $100 US or more will receive the brand new ARISS Challenge Coin. Corporate donors may contact Frank Bauer at KA3HDO at verizon.net or ARISS at arrl.org.

This change also required that the IP address for uploading data needed to change. This means your server settings in RASCAL need to be updated to: New IP: 131.180.122.144 Port: 1099 On July 9 Wouter reported, "The migration has been completed almost without a problem. We still have some minor issues to sort out. Telemetry submission is operating normally but the database performance seems slow. This makes processing more difficult on our end. New user accounts cannot be created but new users can successfully submit received data via the 'guest' account." The team reports that Delfi-C3 is doing great. They have long exceeded the design lifetime of the satellite and she continues to work well. They appreciate your help in acquiring data of Delfi-C3 and hope that you continue to track their "old" bird in the future as well! [ANS thanks Wouter Weggelaar, PA3WEG and the Delfi-C3 team for the above information] --------------------------------------------------------------------- CAMSAT Launch Postponement A launch postponement has been announced for Beijing?s new CZ-6 rocket which is planned to carry a constellation of amateur radio satellites. Soon to be launched six CAMSAT satellites CAS-3A to F have now been named as XW-2 (Hope-2) amateur satellite system, and correspond to the XW-2A to F. All the satellites have completed environmental testing, currently being burn-in tests, everything is underway. The satellites will be moved to the launch center in mid-August and launch date has been postponed to early September.

In-Reply-To: References: <1436630658.19950.YahooMailAndroidMobile@web121004.mail.ne1.yahoo.com> Message-ID: Hi Jan, I've donwloaded the IQ file and run the demodulated audio through soundmodem. The performance is quite impressive indeed. It was also nice to see the 2400 bps BPSK activity. Soundmodem could decode de 2400 bps BPSK signals quite well. Last night I monitored QB50p1 with soundmodem and warbler. As Ken has observed, soudmodem decodes about twice more frames. I had the BitRecovery in sourmodem set to 1. This may have helped as well a little. It would be quite good if FEC was more widely used in amateur satellite projects. Monitoring the BPSK1200 signals from FunCube-1 shows clearly the power of FEC. Sometimes we can barely hear the signal or there is a deep fading and frames are correctly decoded. The BPSK1000 used in ArissSat-1 was another excelent demonstration of the benefits of FEC. 73, Edson PY2SDR --- - We humans have the capability to do amazing things if we work together. - N?s seres humanos temos a capacidade de fazer coisas incr?veis se trabalharmos juntos.

I replaced all cable with LMR-400 (about a 50' run) and new solder on N connectors, and tested them, but no matter what I get horrible high SWR. I redid the ends, I took the whole antenna down, took it apart, checked and redid all connections, hooked it up to the radio in the shack, NO high SWR.. Took it back up installed on the roof, and same old horrible high SWR. Any clue what the problem could be? Thanks!

My original EB-144 had a failed connection at the coax connector center pin inside the antenna center assembly which initially appeared as an intermittent depending on the torque applied when attaching the feed line. That connection is difficult to repair as you have to desolder the short piece of feed line from the balun PCB and then remove the connector from the body; I was able to do it and M2 to their credit replaced mine very quickly as the eggbeater was to be our ARISS contact backup antenna only a few days later (the fault showed up at the ARISS site when setting up). If this is the case with yours send me a note and I?ll forward the pix I took of the inside the body of the center assembly. 73 - Dino KL0S On Jul122015, at 2349 PM, Lee Maisel wrote: > Hello, > > I have an M2 EB-144 eggbeater, and am going crazy trying to figure out why I get high SWR and it is not working. > > I replaced all cable with LMR-400 (about a 50' run) and new solder on N connectors, and tested them, but no matter what I get horrible high SWR. > > I redid the ends, I took the whole antenna down, took it apart, checked and redid all connections, hooked it up to the radio in the shack, NO high SWR..

A while ago, we have implemented in South America a web page that helps people get in touch through the birds. It is easy to log a contact and allows other people to see where and when activity is or will be. It also sends email to log reporters of last activity entry, also allows contact each other for a particular log. Although it is in Spanish, think you can see how easy and straightforward it is, just one screen and no previous registering. This function helped since availability to quite increase South America satellite activity. You can see online at http://lu7aa.org.ar/log.html or http://amsat.org.ar?f=z Perhaps an application like this in Amsat-NA could help avoid unpopulated passes in your area. 73, lu7abf, Pedro Converso Buenos Aires, Argentina www.amsat.org.ar From mail at mike-rupprecht.de Mon Jul 13 16:32:48 2015 From: mail at mike-rupprecht.de (Mike Rupprecht) Date: Mon, 13 Jul 2015 18:32:48 +0200 Subject: [amsat-bb] Deorbitsail decode program ?

I can very occasionally work into N. Eu. with very little time available. I suggest we unofficially designate a "watering hole" frequency for DX efforts. We had this on AO-40 sobsob) and it worked pretty good. I suggest 145.947 for this effort. Either cw or SSB. Most likely CW as signals are marginal at low elevations. With little time available it will easier to find and make these contacts. I have not heard Mika OH8MBN for awhile or few other N.Eu. stations. So you Gents across the pond at near your LOS try 145.947. You can put a note on this bb for a heads up warning. 73 Bob W7LRD CN87 Seattle Wa.

It is not like a terrestrial FM repeater... the timer is not affected by the amount of 'on air' activity. It WILL shut the repeater off ten minutes after it was last reset. It does not matter where over the planet it is at the time. It will shut off in the middle of a busy pass, even in the middle of someone's transmission. The only thing that resets it, is transmitting the proper 74.4 Hz reset tone. And keep in mind, it will not retransmit your signal while sending the 74.4 Hz tone... it will transmit again the next time it receives a signal with the 67 Hz tone. This is important information, even for beginning operators to be aware of, because when the timer needs to be reset, it needs to receive a clear signal. If stations of equal strength keep trying to transmit at the same time as a station trying to reset the timer, signals will collide and the satellite will not receive the reset tone. I suppose it's a crap shoot as to who should or will reset the timer, but if in doubt, err on the side of caution and stop transmitting. Especially if you are have a minimally powered station such as an HT. Unless of course, it's a late night pass and you are the only one on. =^) I just wanted to get this information out there so new satellite operators are educated properly. Proper understanding is key to effectively using a shared resource such as a satellite repeater/transponder. And that goes for new and experienced operators alike... =^) 73, Kevin N4UFO From kb2m at arrl.net Tue Jul 14 14:24:21 2015 From: kb2m at arrl.net (kb2m at arrl.net) Date: Tue, 14 Jul 2015 10:24:21 -0400 Subject: [amsat-bb] remote sat ops Message-ID: <02f901d0be40$c71b3da0$5551b8e0$@net> Is anyone using TeamViewer (or any other remote PC control s/w) to control their sat station remotely?

Any suggestions from experienced remote sat ops before I start looking? 73 Jeff kb2m From bruninga at usna.edu Tue Jul 14 14:33:27 2015 From: bruninga at usna.edu (Robert Bruninga) Date: Tue, 14 Jul 2015 10:33:27 -0400 Subject: [amsat-bb] Golden Packet gaps at SamsPT NY and Mt Equinox in VT. Message-ID: For Saturday's 6th annual golden packet event from Georgia to Maine we still have 2 gaps. One at Sam's PT NY and the other on Mt Equinox in VT. This is a 4 hour event starting at noon. Sam's point is a walk-up so the ideal radio is a Kenwood TH-D72 HT (it digipeats), but Equinox is a driveup. I ask here on AMSAT, because many portable satellite operators have these radios. See http://aprs.org/at-golden-packet.html If we are unable to close those links, then we will open the channel up to any other mountain topers or APRS hikers anywhere on the east coast to join the channel. Be sure to let us know for planning.

A few of us are using teamviewer for the HAMTV video downlink ground stations. Not for transmit but receive and streaming. Upsides: -Free for non commercial use -Easy to use -Easy file transfer to get files to & from the PC. -Gets through firewalls and shows if PC is on line easily. -Other alternatives are expensive or have issues. -Teamviewer has some audio options to get sound from PC Downsides -Uses monitor resolution, if monitor AC power is off resolution can change. I left my monitor sleep ALWAYS. (Fixed in other software using one virtual monitor -PC must be on, If PC fails to start up, no luck. Even if forced on in PC bios I have seen it fail to power up. I will try a UPS in line. -If teamviewer.com goes bye bye so does your link. Their site is needed for use. In general You need a good internet connection with half decent uplink and downlink speeds that never needs to be physically reset once in a while. Any screen share type remote access is going to be more laggy than dedicated remote system. I have also tested with relay remote control My tests used an arduino, with a serial terminal to turn on and off relays. The idea was that no matter the operating system, you just send a command to turn on and off relays. >From a rotator/antenna point of view you need everything bullet proof -Top quality well maintained rotator, ideally with video camera view of direction. -Over rate everything for hurricane weather. -Lightning protection, everything fused, possibly self resetting fuses. -Possibly a way to power off all radios/disconnect coax etc. to reduce the chance of damage. -Time out timers on transmit etc. -SWR checking (e.g. with webcam) -Webcam for checking display on radio -Try to make switches fool proof and give feedback as to current state. -Expect people to move things or plug things out by accident. For live transmit audio you may want a phone patch, as streamed audio may not be up to the job. If at all possible some one available to reset everything. I would advise testing it remotely (locally) before leaving the site, for a week or two. Try operating it from another room. Try to document and photograph everything. My remote station is 3 hours each way/6 hours round trip with personnel on site, but it still requires regular visits. Most issues are with moving parts & power/internet glitches. There is no substitute to being on site yourself. Try to understand your equipment 100% before operating remote.

Apollo-Soyuz (or Soyuz-Apollo in Russia) represented the first joint USA-Soviet mission and set the stage for follow-on Russia- USA space collaboration on the Space Shuttle, Mir Space Station and the International Space Station. The Soyuz and Apollo vehicles were docked from July 17-19, 1975, during which time joint experiments and activities were accomplished with the 3 USA astronauts and 2 Soviet Cosmonauts on-board. Apollo-Soyuz was the final mission of the Apollo program and the last USA human spaceflight mission until the first space shuttle mission in 1981.

A little background on my experience with remoting. I first tried remoting about 10 years ago. At that time my 100 watt system was composed of a Kenwood TS-2000, a Steppir 4L beam, several wire antennas for the low bands, and an Oscar class satellite antenna system. I used TXManager to control the radio on HF and the local repeaters, WiSP for sat work, and SKYPE for the audio. I worked HF, FM sats, and local repeaters. When I retired from my fulltime job that required a lot of travel I had no need for a remote system anymore. This time around I'm living in three different locations. The one in NJ near Philadelphia is the main station where the HF and sat antennas are currently located. At my shore condo also in NJ, there is zero places to put up antennas. At my recently acquired Florida waterfront home I plan on putting up a small tower, and a vertical grounded into saltwater. I'm also acquiring the antennas, rotors, etc to put up a smaller yet, sat antenna system. Right now I'm remoting a 600 watt K3 system with one antenna using Remoterig.com hardware. I use TeamSpeak to 'see' my panadapter s/w and to control the KPA/KAT500 600 watt tuner/amp system. I used this setup every day while in Florida for several months setting up the new QTH. I also use this setup while down the shore at my property there. I really missed working the sats when I was in Florida for three months, so I started to think about remoting my sat station also. It looks like I will be once again going to be using SKYPE for the audio, same as I did ten years ago. The lack of fullduplex audio seems to be an issue with the SSB birds, last time I did this I just worked the FM birds, thanks Dave PVH for the SKYPE info to try on the linear bird's. Thanks to Erich for the hidden tx/rx controls, and the added rotor info in his SatPC s/w. I was also thinking that it might be a bit easier to just put a sat station up in Florida, but then I thought it's a much better shot into EU from NJ then from FL so even if I got OTA from Florida I still might like to use NJ as a alternate TX site. Lots to think about, what a great hobby for a retired person :-) At QRZ I'm kinda tracking what I'm doing, along with some pictures, just goto kb2m..... 73 Jeff kb2m -----Original Message----- From: Erich Eichmann [mailto:erich.eichmann at t-online.de] Sent: Tuesday, July 14, 2015 12:30 PM To: kb2m at arrl.net; AMSAT-BB at amsat.org Subject: Re: [amsat-bb] remote sat ops Jeff, You can remotely switch the radio between RX and TX (PTT).

Also got in with 5W. * on 40 deg pass (in Annapolis) heard a single 5 bar packet and no decode. NOTICE, the first three were at the beach with no real planning as to building obstructions. But apparently the noise open squelch was S0. But in Annapolis, after hearing nothing (1 packet) I opened the squelch to see a full 3 bars of noise. Remember, the radio ALWAYS shows ZERO S units until the squelch actually opens, so the presence of even S9 broadband noise will show nothing and HEAR nothing unless you open the squelch manually! The Baghigawatt area defense radar on 149 MHz in the DC area was operating at the time. Again, shows the value of having any SATGATE OMNI antnenna on the ground well below horizon (and only able to see sky above 30 deg)... P.S. On this 19" magmount whip, the 435.350 PSK31 came in FINE! Remember this is a 3/4 wave vertical on UHF. So to pick up the needed 3dB more on VHF, the next tests should use a 3/4 wave at VHF or about 58 inches... Much more testing needed. de WB4aPR, Bob ------------------------ original message ---------------------- Some EZNEC models: 1/4 wave with radials: -2 at 30 and -6 at 60 ==> Basically a dipole pattern 3/4 wave with radials: +2 at 30 and -1 at 60 ==> 4 to 5 dB better, 2 dBi max 3/4 wave w 3' gndpln: +3 at 30 and +1 at 60 ==> 5 to 7 dB better, 3.3 dBi max 3/4 wave w 6' gndpln: +2 at 30 and +3 at 70 ==> 4 to 9 dB better, 5.5 dBi max 3/4 wave w 9' gndpln: +3 at 30 and +3 at 65 ==> 5 to 9 dB better,5.3 dBi max 3/4 wave perfect gnd: +3 at 30 and +3 at 68 ==> 5 to 9 dB better, 6.9 dBi max Even the 3/4 with just the four 19" radials gives a huge 4 to 5 dB improvement over a classic ground plane for omni satellite SATgate work. Also, this antenna does not need to be high. Just see sky above 30 deg. In fact, is better to be low to reduce terrestrial QRM. Notice too that the Lilenblatt, eggbeaters, and all other "omni"s that try to keep their gain down on the horizon, are equally as poor as the 1/4 wave vertical at these higher elevations. This is OK for strong satellits like the ISS with 5 to 10 watts, but abisimal when all that gain on the horizon is completely wasted when you cannot hear the satellite anyway because it is 6 to 10 dB farther away! The result is these "omni's" give up the 4 to 9 dB at higher elevations where the satellite is much stronger. See the Omni SATGATE page: http://aprs.org/aprs-satellite-igate-antennas.html Summary: The 3/4 wave vertical should make it so you CAN hear weak LEO satellites 5 to 9 dB better when they are closer and does this by giving up on hearing them when they are so far away you can't hear them anyway! Bob, WB4APR -----Original Message----- From: Robert Bruninga [mailto:bruninga at usna.edu] Subject: RE: [aprssig] APRS Satgate Antenna page > One question,what constitutes a large ground plane? > Is it 12"or 12'? Is it a multiple of the vertical whip? Good question. Most people think that four 1/4 wave radials make a ground plane. But if you model a 1/4 wave vertical over 1/4 wave radials, all you get is the exact pattern of a DIPOLE. The radials are just providing a "groundplane" to complete the electrical part of the antenna and give a good match. They do not affect the pattern at all. I modeled verticals over 6' or larger ground planes and only found that you get the added "reflection" gain when the ground plane starts getting that big or more. I wish I had time to use EZNEC to show the added gain (skyward) versus the size of the ground plane. And how "radials" (above actual ground) have nothing to do with the "pattern". SO, the bigger the better. It should be worth 2 to 3 dB if you could make it very large...

Examples are last minute grid activations, unexpected satellite mode commands, requests for critical telemetry after a launch, etc. These normally go through promptly, but occasionally get held for two primary reasons: While AMSAT-BB and SAREX are both open lists, that means they are open for membership. In order to post to the list, it normally must be from the same account you originally registered. For instance, if you registered from your home account, and post from your office account, it will normally be held for release by a moderator. Likewise, some people have all their email forwarded to a single account from which they reply. We can easily create a filter to pass the second address, but that is not automatically done on the first posting, and does require moderator action. Both mailing lists receive literally dozens of pieces of spam for each legitimate message. As part of the filtering process, emails larger than 40-50kB are blocked. This usually happens to legitimate email when someone attempts to attach a large file, or replies to a long message without trimming. These also require moderator intervention, and are normally not approved but bounced back to the originator for adjustment. Also, there is a limit to the number of addresses before an email is held as potential spam. I have seen legitimate email sent to 20+ addresses. We have a team of volunteer moderators, but they are not available 24/7. The result is that a message sent in the evening or on a holiday, US time, may well be held for 10-12 hours before being released. So, if it absolutely, positively needs to be distributed promptly: 1. Post from the same account you registered for, or one which from past experience you know has been flagged as acceptable. 2. Post a message less than 40 kB, with no attachments which will always be stopped. (Pictures should be included by a link.) 3. Send it to AMSAT-BB, SAREX, and a few other addresses a most. If you must send to a large distribution list, send to them, and another copy to the AMSAT lists. 4. Consider also posting to the AMSAT Twitter and Facebook accounts. There is overlap in membership, though at present it is far from 100%. 73s, Alan WA4SCA From johnbrier at gmail.com Wed Jul 15 11:57:36 2015 From: johnbrier at gmail.com (John Brier) Date: Wed, 15 Jul 2015 07:57:36 -0400 Subject: [amsat-bb] Live video feed of ARISS contact with Pima County 4H/Vail Vaquero's 4H Club Tucson, AZ Message-ID: Apologies if this was mentioned already, but I hadn't seen it.

For NO-84, it won't digipeat anything sent via PSAT, but you can use ARISS or APRSAT for the path. I have not used NO-44 in a while, but when it is getting enough power from its solar panels it does work with W3ADO-1. NO-84 is actually a good APRS digipeater, even though not many stations are picked up by the Internet gateways. It is possible that the gateways that work fine with the ISS and its stronger signals just don't do as well with the weaker signals from NO-84. With my TH-D72A and Elk, I hear NO-84 well, and it seems to hear me OK once it is up a few degrees above the horizon during its passes. Hope to see/hear you soon on NO-84. I have logged one packet QSO on that satellite, and will try for more. I also want to try the 10m/70cm PSK31 transponder, but for now my TH-D72A and Elk antenna is able to use NO-84's packet digipeater well. Good luck, and 73!

OK, I am holding the antenna and pointing it at the satellite, twisting as needed to keep up with what the satellite is doing in orbit. As I mentioned in my earlier post, I am using a TH-D72A HT - just 5 watts. What path (UNPROTO) are you using with NO-84? PSAT doesn't work, but ARISS or APRSAT will work. I've used both of those successfully. Remember that NO-84 transmits in the millwatt range, where ISS has many times more transmitter power for packet. I think this is also where many of the gateways are having difficulties with NO-84 - it just isn't as strong as the ISS. 73!

About 90% of the packets on the air are overdeviated, distorted, skewed, unbalanced, not properly emphasized or demphaasized or neither. These work "fine" terrestrially when weak signals are not involved but may be 20 dB or more away from good performance with weak signals or picky receivers. I can decode PSAT with 5 bars on the Kenwood TH-D72, but have no other experience to compare. I remember good balanced tones did 3 bars on a D700, but typical bad terrestrial signals would not decode sometimes with all 9 bars! The ear can tell between good tones (listen to ISS) and bad tones (listen to 144.39!) We have a bgighawatt experimental air defense radar near Wash DC on tethered balloon blasting out power at 143 and 149 mHz and all over the place. I wonder if PSAT gets overloaded by that? PSAT does not listen to carrier detect, so when it has a packet to send, it sends it.

About 90% of the packets on the air are overdeviated, distorted, skewed, unbalanced, not properly emphasized or demphaasized or neither. These work "fine" terrestrially when weak signals are not involved but may be 20 dB or more away from good performance with weak signals or picky receivers. I can decode PSAT with 5 bars on the Kenwood TH-D72, but have no other experience to compare. I remember good balanced tones did 3 bars on a D700, but typical bad terrestrial signals would not decode sometimes with all 9 bars! The ear can tell between good tones (listen to ISS) and bad tones (listen to 144.39!) We have a bgighawatt experimental air defense radar near Wash DC on tethered balloon blasting out power at 143 and 149 mHz and all over the place. I wonder if PSAT gets overloaded by that? PSAT does not listen to carrier detect, so when it has a packet to send, it sends it.

About 90% of the packets on the air are overdeviated, distorted, skewed, unbalanced, not properly emphasized or demphaasized or neither. These work "fine" terrestrially when weak signals are not involved but may be 20 dB or more away from good performance with weak signals or picky receivers. I can decode PSAT with 5 bars on the Kenwood TH-D72, but have no other experience to compare. I remember good balanced tones did 3 bars on a D700, but typical bad terrestrial signals would not decode sometimes with all 9 bars! The ear can tell between good tones (listen to ISS) and bad tones (listen to 144.39!) We have a bgighawatt experimental air defense radar near Wash DC on tethered balloon blasting out power at 143 and 149 mHz and all over the place. I wonder if PSAT gets overloaded by that? PSAT does not listen to carrier detect, so when it has a packet to send, it sends it.

This PSK31 TX-only software for PSAT PSK-31 solves three problems! 1) as a separate TX-only program, it lets everyone run FULL DUPLEX with their existing PSK31 for receive 2) It makes your signal constant in the waterfall for You 3) and for everyone else even if they are not running anything special!

NORAD ID 40654 is labeled as PSAT in the SpaceTrack website where we get all the rest of the our Keplerian elements for other satellites in TLE format. We have chosen to follow SpaceTrack's lead to avoid confusion in the future. Note ... because PSAT was launched on a military rocket flight, we cannot get the TLEs directly from SpaceTrack. We can get them from the satellite owner/operator. This is how we acquire the TLEs for PSAT and BRICSat each week. But the owner/operator, in many cases, does not try to sort out who is who on a launch with multiple cubesats. The TLEs we get from the owner/operator are not labeled as BRICsat and PSAT, so we rely on our own amateur community (Nico Janssen, PA0DLO and others) to sort the list of TLEs out for us and to verify who is who.

I'm interested in how well it tracks when the satellite is at a very high elevation and the Doppler is >3 Hz/s.? I suspect the error is going to be mostly in the estimates of the orbital elements, but we'll see.? I will try to join you on the pass when I can cobble together an uplink and a downlink in the same place--probably next week sometime after I get back from vacation. I think you should be able to share a sound device on most OS's, but I have not tried.? I assumed it would work on modern Windows OS's because of the hardware abstraction.??The program appears to run fine on OSX, but I have not tried running CocoaModem or some other software next to it.??Ultimately I could also add a demodulator to the program itself, but that will take some work....I know several hams have separate sound cards for radio stuff, so I may need to add a device selection option in case the system default (or whatever Java picks as the default) isn't what you want. The audio frequency displayed in DopplerPSK is the audio frequency being send to the radio, not what you should expect in the passband of your downlink receiver.?The LO on?PSAT?is apparently a bit below 28120 KHz, so if your radio was tuned to 28120 USB (suppressed carrier frequency) you would expect to be a bit higher than 2000Hz in the FM passband: http://www.urel.feec.vutbr.cz/esl/files/Projects/PSAT/P%20sat%20transponder%20WEB%20spec02.htm In general,?if you want to be lower in the passband I would lower your transmitter RF frequency rather than the audio frequency going to the transmitter.? The reason being that if you have any non-linearity in the audio chain you don't end up?transmitting a?harmonic higher in the band that might bother someone else.? Of course, you can probably see if this is an issue or not since the satellite also serves as a crude signal analyzer :-)? I chose 2000 Hz as a center since at maximum Doppler of around 700 Hz, the ~2700 Hz tone?should go through the transmitter's IF filter without too much attenuation while?keeping all the third harmonics and most of the time the second harmonic?above the cutoff of a 3 KHz IF filter.? Every radio is a bit different, however.? You may find that the 1500Hz sweep in the program shows you all your passband ripple?in your IF filter :-) Since it works, I'm more motivated to improve the ergonomics of the interface.? Much of that depends on the unique operating practices of satellite operation. Andy K0SM/2 On Thursday, July 16, 2015 12:31 AM, KO6TZ Bob wrote: The software worked great !!!?

So I envision some continuously running brag text including CQ's the call, the HF antenna, the power, the grid, the location in DDN/DDDW whole degrees maybe (for APRS purposes), the downlink antenna, and so forth. And then maybe the looping uplink will stop at the next item separator and allow the operator to inject keyboard text. In other words, the loop just runs. But if the operator begins typing (maybe he sees a buddy in the dowonlink) he just starts typing and the LOOP stops at the next break in loop elements and inserts the typed text. Im thinking that elements in the brag string would be separated by " - " but then when ever the operator types text, then it is inserted in the stream beginning with [ then text goes here and ends with a ] when he hits the enter key? By having a common system of continuous brag items and interjected live text, then we all have consistent expectations as to what the PC is doing versus the operator?

I don't see any reason why that couldn't be done.? I'll give it some thought.? It's an experiment, after all.... Another way to do this is to just invent a mode that has two data streams interleaved with each other, source-coded for the data you want to send (a la JTx modes) but that breaks the universality of BPSK31 and varicode.? I really like the idea that someone can plug a handheld into a laptop or tablet running off-the-shelf software and see something meaningful.? DopplerPSK?already has a rudimentary "macro" format.? Have a look at the PDF on the download page and you'll get the gist of how it works.? It does not have any substitution functionality yet (like wildcards for the other stations' callsigns), but you could make a file with an arbitrary-length fixed message just fine.? I have planned a loop functionality (it's in the macro file format itself), but I didn't get around to implementing it yet....right now you can just press the button several times to stack the looped message in the buffer.? Just make sure there are spaces at the?end of the text so that work don't run together between the boundaries.? One press of the macro button just dumps that text into the type-ahead buffer. The "clear buffer" button will empty the buffer and you can start typing whatever you want.? You can use that to interrupt a macro message that is sending.? The ergonomics of having a conversation are not perfect (you can't copy paste into the text window and get it to send for example--which slow typists might want), but it's functional enough to be somewhat useful. Also of note for those not aware, sending uppercase requires many more bits in the varicode table?and?is going to be more prone to bit errors due to burst noise (like, say a quick fade from a?rotating satellite).? You can probably send your callsign a couple times in lowercase in the same amount of time it takes in all caps.? That's pretty poor FEC, and convolutional codes can address some of that, but for right now DopplerPSK is stuck with plain vanilla BPSK31 until someone implements a different scheme.? I'm not really sure this a big problem to be solved, though.

So I envision some continuously running brag text including CQ's the call, the HF antenna, the power, the grid, the location in DDN/DDDW whole degrees maybe (for APRS purposes), the downlink antenna, and so forth.? And then maybe the looping uplink will stop at the next item separator and allow the operator to inject keyboard text. In other words, the loop just runs.? But if the operator begins typing (maybe he sees a buddy in the dowonlink) he just starts typing and the LOOP stops at the next break in loop elements and inserts the typed text. Im thinking that elements in the brag string would be separated by " - " but then when ever the operator types text, then it is inserted in the stream beginning with [ then text goes here and ends with a ] when he hits the enter key? By having a common system of continuous brag items and interjected live text, then we all have consistent expectations as to what the PC is doing versus the operator?

In my setup TX audio is fed by a virtual audio cable set to match the 48K sample rate that DopplerPSK is using. Folks using windows should set the recording device side of their soundcard to a 48K sample rate (it usually defaults to 44.1K). You are correct that the uplink frequency is high, I apply a -300 Hz calibration offset. Thanks for all your work on this.

I'm interested in how well it tracks when the satellite is at a very high elevation and the Doppler is >3 Hz/s. I suspect the error is going to be mostly in the estimates of the orbital elements, but we'll see. I will try to join you on the pass when I can cobble together an uplink and a downlink in the same place--probably next week sometime after I get back from vacation. I think you should be able to share a sound device on most OS's, but I have not tried. I assumed it would work on modern Windows OS's because of the hardware abstraction. The program appears to run fine on OSX, but I have not tried running CocoaModem or some other software next to it. Ultimately I could also add a demodulator to the program itself, but that will take some work....I know several hams have separate sound cards for radio stuff, so I may need to add a device selection option in case the system default (or whatever Java picks as the default) isn't what you want. The audio frequency displayed in DopplerPSK is the audio frequency being send to the radio, not what you should expect in the passband of your downlink receiver. The LO on PSAT is apparently a bit below 28120 KHz, so if your radio was tuned to 28120 USB (suppressed carrier frequency) you would expect to be a bit higher than 2000Hz in the FM passband: http://www.urel.feec.vutbr.cz/esl/files/Projects/PSAT/P%20sat%20transponder%20WEB%20spec02.htm In general, if you want to be lower in the passband I would lower your transmitter RF frequency rather than the audio frequency going to the transmitter. The reason being that if you have any non-linearity in the audio chain you don't end up transmitting a harmonic higher in the band that might bother someone else. Of course, you can probably see if this is an issue or not since the satellite also serves as a crude signal analyzer :-) I chose 2000 Hz as a center since at maximum Doppler of around 700 Hz, the ~2700 Hz tone should go through the transmitter's IF filter without too much attenuation while keeping all the third harmonics and most of the time the second harmonic above the cutoff of a 3 KHz IF filter. Every radio is a bit different, however. You may find that the 1500Hz sweep in the program shows you all your passband ripple in your IF filter :-) Since it works, I'm more motivated to improve the ergonomics of the interface. Much of that depends on the unique operating practices of satellite operation. Andy K0SM/2 On Thursday, July 16, 2015 12:31 AM, KO6TZ Bob wrote: The software worked great !!!

If your Uplink freq is 28.119725 your downlink center frequency should match your uplink center frequency. The DopplerPSK program simplifies operating NO-84 greatly.

You only have feedback after sending the 74.4 Hz tone when you switch back to the 67.0 Hz tone and transmit through the satellite (as long as you are working full-duplex), or when you hear another station transmitting through the satellite with the 67.0 Hz tone.

That would have made the satellite compatible with ISS, other APRS satellites and APRS-IS. Unfortunately, a short time before launch, we realized that technically we couldn't keep the intended 145.825MHz transceiver in the final satellite configuration but we still wanted to make some contribution to amateur radio in space. After a quick research we discovered that the 2nd transceiver onboard Duchifat1, the ISIS (Netherlands) TRXUV planned for Duchifat1's command and telemetry can be programmed to also accept APRS packets!, however, limited to 14 characters long. Also, the downlink digital modulation was not the common space APRS of 1200bd AFSK but 1200bd BPSK, and the uplink frequency is in the UHF band. We therefore came with the idea of supporting COMPRESSED APRS, and instead of the standard digipeater, we implement kind of "store&forward" function in which the satellite collects packets during its flight in orbit and the students of Herzliya Science Center will download those packets and display them on a world map in a web site programmed by them. We published here a few weeks ago the opening of this service and put in our web site detailed instructions on how to use the Byonics TinyTrak4 (TT4) tracker, with or without GPS to generate packets in the required format that Duchifat1 will accept. So far, TWO pioneers used this service. THANKS PETER & MIKE! While the TT4 solution is still the best we know for sending your actual live position to Duchifat1, we are happy to announce the 'APRS Encoder', a new tool in our web site that can generate for you the COMPRESSED APRS packet for Duchifat1. The input for the new APRS Encoder is the station's (or nearby) coordinates set that can be obtained from Google Maps, so this solution is naturally adequate for stationary base stations, while mobile stations should still use the Byonics TT4. ?The output of the APRS Encoder is a 14 character long Compressed APRS packet that can be converted to 1200bd AFSK with a hardware TNC or software like MIXW ? just copy the 14 chars string and paste it into the MIXW window. The MIXW should be set to mode Packet, using the most common "VHF 1200 baud (Standard 1200/2200Hz)" setting. Prior registration is required. All the details on the satellite, the registration and the APRS Encoder are at this link: www.h-space-lab.org Please read all the documentation in the site. We wish you all good luck and enjoy! 73 from 4X4HSC team: instructors 4Z1WS and 4X1DG, and the students!

It can be expected that, as usual, she will stay in this mode until Sunday evening (UTC time) A heads up for next weekend ? As AMSAT-UK is holding their Collloquium event in Guildford Surrey, it is expected that FUNcube-1 will be switched to continuous transponder mode , exceptionally, from Thursday evening (July 23rd) until either Sunday evening (July 26th) or, more likely, Monday evening (July 27th). This will enable the Colloquium attendees to view or demonstrate and enjoy the transponder operations for the maximum possible time.

Tim holds the call sign KG5BVI and is expected to use the special call GB1SS from the amateur radio station in the Columbus module of the ISS. Tim will launch to the ISS in December of this year and will spend 6 months working and living in space. The Amateur Radio competition is a collaboration between the UK Space Agency, the Radio Society of Great Britain (RSGB) and the European Space Agency (ESA). Selected schools will host a direct link-up with the ISS during a two-day, space related STEM workshop which will be the culmination of a large range of learning activities using space as a context for teaching throughout the curriculum. ARISS UK (Amateur Radio on the International Space Station) will provide and set up all necessary radio equipment such as low earth orbit satellite tracking antennas and radios, to establishing a fully functional, direct radio link with the ISS from the schools? very own premises. In a ten-minute window when the ISS will be over the UK, an amateur radio contact will be established with Tim, and students will be able to ask him questions about his life and work on board the ISS. Owing to the nature of scheduling the links, which is dependent on geography, the exact orbit of the ISS and the crew schedules, the exact dates and times for possible links will not be known until 2 weeks before the link up is scheduled. The shortlisted schools will all be prepared for such scheduling challenges and, by having a number of schools, we can ensure that all links are used. Jeremy Curtis, Head of Education at the UK Space Agency, said: We?re delighted with the amount of interest in this exciting project and look forward to working with the selected schools as they make a call into space. Both Tim?s space mission and amateur radio have the power to inspire young people and encourage them into STEM subjects. By bringing them together we can boost their reach and give young people around the UK the chance to be involved in a space mission and a hands-on project that will teach them new skills. The following schools have been shortlisted for a possible ARISS call with Tim whilst he is in orbit on the ISS: Ashfield Primary School, Otley, West Yorkshire The Derby High School, Derby The Kings School, Ottery St Mary Norwich School, Norwich Oasis Academy Brightstowe, Bristol Powys Secondary Schools Joint, Powys Royal Masonic School for Girls, Rickmansworth Sandringham School, St Albans St Richard?s Catholic College, Bexhill-on-Sea Wellesley House School, Broadstairs John Gould, G3WKL, President of the RSGB, said: The Radio Society of Great Britain will be delighted to support shortlisted schools by teaching their pupils about amateur radio and helping them through their licence exams where appropriate. Members of our Youth Committee are based across the UK and will be keen to visit the chosen schools in their area and chat to the pupils. The ARISS UK Operations team will now work with the shortlisted schools to prepare them for this exceptional opportunity during the mission of the first British ESA Astronaut.

The solar cells will be used to build the first prototype solar panels for testing with the power unit. The electrical power system (EPS) is the sub-system that provides various other systems and the payload with power, and controls the charging and conditioning of the batteries. The first prototype was tested with panels borrowed from the Denel Dynamic CubeSat project. "We are looking forward to building our own panels to meet the physical dimension requirements of the space frame," Hannes Coetzee, ZS6BZP, said. Fritz Sutherland, ZS6FSJ, who built the prototype, which he showed at the recently held SA AMSAT Space Symposium, designed the EPS. Both Hannes Coetzee and Frik Wolff, ZS6FZ, who recently joined the project team, will build the solar panels. The Kletskous project is funded by donations from radio amateurs.

That would have made the satellite compatible with ISS, other APRS satellites and APRS-IS. Unfortunately, a short time before launch, we realized that technically we couldn't keep the intended 145.825MHz transceiver in the final satellite configuration but we still wanted to make some contribution to amateur radio in space. After a quick research we discovered that the 2nd transceiver onboard Duchifat1, the ISIS (Netherlands) TRXUV planned for Duchifat1's command and telemetry can be programmed to also accept APRS packets!, however, limited to 14 characters long. Also, the downlink digital modulation was not the common space APRS of 1200bd AFSK but 1200bd BPSK, and the uplink frequency is in the UHF band. We therefore came with the idea of supporting COMPRESSED APRS, and instead of the standard digipeater, we implement kind of "store&forward" function in which the satellite collects packets during its flight in orbit and the students of Herzliya Science Center will download those packets and display them on a world map in a web site programmed by them. We published here a few weeks ago the opening of this service and put in our web site detailed instructions on how to use the Byonics TinyTrak4 (TT4) tracker, with or without GPS to generate packets in the required format that Duchifat1 will accept. So far, TWO pioneers used this service. THANKS PETER & MIKE! While the TT4 solution is still the best we know for sending your actual live position to Duchifat1, we are happy to announce the 'APRS Encoder', a new tool in our web site that can generate for you the COMPRESSED APRS packet for Duchifat1. The input for the new APRS Encoder is the station's (or nearby) coordinates set that can be obtained from Google Maps, so this solution is naturally adequate for stationary base stations, while mobile stations should still use the Byonics TT4. The output of the APRS Encoder is a 14 character long Compressed APRS packet that can be converted to 1200bd AFSK with a hardware TNC or software like MIXW ? just copy the 14 chars string and paste it into the MIXW window. The MIXW should be set to mode Packet, using the most common "VHF 1200 baud (Standard 1200/2200Hz)" setting. Prior registration is required.

The first is about the Amateur Radio transponder on the geostationary satellite Es?hail 2 by Thani Ali al-Malki followed by Adventures of a Hacker Turned Ham by Michael Ossmann AD0NR. The night begins with a short presentation on what will be the first Amateur Radio transponder on a geostationary satellite, a project of the Qatar Amateur Radio Society, with help from AMSAT DL (Germany). The satellite, Es?HailSAT-2, is owned by the Qatar Satellite Company, and senior engineer Thani Ali al-Malki will give the details. Western Hemisphere hams will be disappointed that the satellite footprint won?t cover anything in North America or Australia, and just a bit of South America. The satellite is primarily a communications system for Qatar and the Middle East, but the ham transponder will also cover Europe, Africa and western Asia (but also missing the China coast and Japan). Michael Ossmann, AD0NR, founder of Great Scott Gadgets grew up as a computer nerd embracing the hacker ethos. Eventually Michael became very interested in the security of wireless systems such as remote keyless entry, garage door openers, Wi-Fi, and Bluetooth. He designed Ubertooth One, a Bluetooth sniffer that was successfully funded on Kickstarter. Not one to rest, Michael later designed and successfully funded HackRF One, an open source SDR platform that attracted the attention of the amateur radio community. Michael talks about his unique perspective on the community as an outsider looking in, why he resisted getting an amateur radio license for years, and why he finally decided to join. Michael shares his thoughts on what it means to be a hacker, what it means to be a ham, and what amateur radio may look like in the decades to come. TAPR President Steve Bible N7HPR?s introduction establishes the youth theme with an interesting survey of the crowd. http://arvideonews.com/hrn/HRN_Episode_0211.html Previous editions of HamRadioNow http://www.youtube.com/user/HamRadioNow/videos Es?hail 2 geostationary satellite http://amsat-uk.org/satellites/geosynchronous/eshail-2/ [ANS thanks AMSAT-UK for the above information] --------------------------------------------------------------------- AMSAT Events Information about AMSAT activities at other important events around the country.

Moon Day/ Frontiers of Flight Museum, Dallas, TX, telebridge via W6SRJ The ISS callsign was scheduled to be RS?ISS/OR4ISS The scheduled astronaut was Mikhail Korniyenko RN3BF Contact was successful: Sat 2015-07-18 16:58 UTC 84 deg The Moon Day contact was successful with 11 questions asked and 10 fully answered. The answer to the 11th question was lost in the noise at LOS. Participants asked the following questions: 1. How do you get internet? 2. How is your perspective of Earth different from ours who have not been to space? 3. What has been your most exciting and memorable experience during your time on the International space station? 4. As you don't have gravity in the Space Station, and nothing drops or drips down, what happens to a scoop of ice cream in space when it melts? Once it has melted, can you suck it up with a straw? Have you ever tried that? 5. What happens to fire in space? 6. What do you eat when in space? 7. What happens if an astronaut gets sick in space? Do they have a doctor on board? If not, do they have to go back to Earth early for treatment? 8. Has your time on the space station helped in the research of finding a way to send someone to Mars for a longer period of time? 9. If a meteorite, space junk, or another spacecraft collides with the ISS, or there was a fire on board, what kind of emergency procedures would be performed to ensure station integrity and crew safety? 10. What has been your biggest unexpected obstacle, and how did you solve it and still reach your goal? 11. How do you put on your spacesuit to go out in space?

The launch will be from the Chanute Air Museum in Rantoul, Illinois which is approximately 100 miles south of Chicago. The amateur radio payload on this balloon will include: + Telemetry: APRS: 144.390Mhz, APRS.FI: WB9SA-11; QRZ: WB9SA + Cross-Band FM Repeater: Uplink 144.34 MHz; Downlink 446.025 MHz. + SSTV unit will operate on 147.48 MHz using Scottie2 - 72 seconds on 30 seconds off. + 900 MHz tracking system. + DF beacon at 443 MHz Website: http://www.depauw.edu/academics/departments-programs/physics-astronomy/depart ment-research/base/ [ANS thanks the BALLOON_SKED at yahoogroups.com e-mail list for the above information] ARISS SSTV Images Commmemorate 40th Anniversary of the Apollo-Soyuz Mission 40 years ago this week, the historic joint Apollo-Soyuz mission was conducted. Apollo-Soyuz (or Soyuz-Apollo in Russia) represented the first joint USA-Soviet mission and set the stage for follow-on Russia-USA space collaboration on the Space Shuttle, Mir Space Station and the International Space Station. The Soyuz and Apollo vehicles were docked from July 17-19, 1975, during which time joint experiments and activities were accomplished with the 3 USA astronauts and 2 Soviet Cosmonauts on-board. Apollo-Soyuz was the final mission of the Apollo program and the last USA human spaceflight mission until the first space shuttle mission in 1981. To commemorate the 40th anniversary of this historic international event, the ARISS team has developed a series of 12 Slow Scan Television (SSTV) images that will be sent down for reception by schools, educational organizations and ham radio operators, worldwide. The SSTV images are planned to start sometime Saturday morning, July 18 and run through Sunday July 19. These dates are tentative and are subject to change. The SSTV images can be received on 145.80 MHz and displayed using several different SSTV computer programs that are available on the internet. We encourage you to submit your best received SSTV images to: http://spaceflightsoftware.com/ARISS_SSTV/submit.php The ARISS SSTV image gallery will post the best SSTV images received from this event at: http://spaceflightsoftware.com/ARISS_SSTV/index.php Also, as a special treat, on Saturday July 18 the ISS Cosmonauts will take time out to conduct an ARISS contact with students attending the Moon Day/Frontiers of Flight Museum event in Dallas Texas. This Russian Cosmonaut-USA Student contact is planned to start around 16:55 UTC through the W6SRJ ground station located in Santa Rosa, California. ARISS will use the 145.80 MHz voice frequency downlink (same as the SSTV downlink) for the Moon Day contact. For more information on ARISS, please go to our web site: www.ariss.org The ARISS international team would like to thank our ARISS-Russia colleague, Sergey Samburov, RV3DR, for his leadership on this historic commemoration.

I was able to copy one complete picture on a shallow ISS pass at 1431 UTC this morning. The pass had a maximum elevation of only 9 degrees, and the signals were strong even at the low elevation. I posted the picture on my Twitter feed, and you can see it at: http://pic.twitter.com/sEojLbhQkV I used a TH-D72A with my Elk log periodic, recording the audio with a Sony audio recorder. After the pass, I downloaded the recording to my laptop and played it into RX-SSTV. I tried to resync the recording at the two points where there are glitches, and this was the best I could get.

But today I had our 11 year old nephew Juan, who is visiting from Colombia, in the shack. He got an earful on the ISS from me about the SatPC32 tracking map, which we also compared on the globe, and who and what was up there on ISS. ISS passed over Colombia on the 1610 UTC pass too, so he saw how it's possible to see or hear them even from his home. He got a wonderful eyeful with the image we saw come down live, and I explained what the various things in the image were about. But hearing the cosmonaut calling, when I told him it was a real astronaut talking on the ham radio, was a real gol. Eyes wide open! ISS accomplished their mission of bringing "outer space" to kids today, and Juan jumped right on the tell-me-more wagon after the pass with great interest in the ISS, our amateur radio satellites (I showed him other ISS and ARISSat SSTV pictures I had received), and even HF ham radio as we tuned the bands and watched ISS track down across South America and into the Atlantic.

Message-ID: On the last pass 1500 EDT or so, I was hearing a fade almost every 3 seconds in the PSK31 audio downlink. That would be 20 RPM. So I upped the Sun Vector telemetry sample rate to the highest to get now 24 samples per minute. But this plot shows only about 6 RPM. But if the audio is right, then we are sampling below the Nyquist rate and so the plot can be aliasing? So the question is. What do ?you? hear as the audio spin rate in the PSK31 downlink on 435.350?

I was able to get a picture on each pass, and one pass had about 1 2/3 pictures (most of one picture, then a nice and clean picture before LOS). I have uploaded my pictures to the ARISS SSTV picture gallery: http://www.spaceflightsoftware.com/ARISS_SSTV/index.php My 4 pictures are at: http://www.spaceflightsoftware.com/ARISS_SSTV/uploads/10506.jpg (1431 UTC) http://www.spaceflightsoftware.com/ARISS_SSTV/uploads/10554.jpg (1605 UTC) http://www.spaceflightsoftware.com/ARISS_SSTV/uploads/10556.jpg (1610 UTC) http://www.spaceflightsoftware.com/ARISS_SSTV/uploads/10575.jpg (1743 UTC) After the 1610-1613 UTC picture (the third link above), a Russian voice came on the 145.800 MHz frequency. I had not prepared for this, but tried some different uplink frequencies in an attempt to make a voice QSO. This was near my LOS time, and I was unsuccessful. I didn't hear anything that would indicate any station was working RS0ISS. Don't forget that there is an award for copying the current crop of SSTV pictures, which you can apply for online: http://ariss.pzk.org.pl/Apollo-Soyuz/en I wish I had more chances to get more pictures, but the 3 passes this morning were fun to be outside to see what I could get.

In-Reply-To: References: Message-ID: Bob, I started looking at this because the fades on the uplink signal can cause a character synchronization problem with PSK31. Because of the variable character length, you can't write a synchronous decoder that locks onto the character period to help correct framing errors. I was interested in the "rotation rate" (or so I thought) because the fade period might inform how to do any FEC or other error correction scheme. I've only looked at the recording that that W0DHB made and posted to the list. The PSK signals in the passband show a relatively short fade period and independent uplink signals are not always in phase. In fact, it looks like the period of the fade appears to slowly drift independently--between 1.8 to about 3 seconds in this recording. I'll take another look and see if I can find a really good section of the recording where you can see the independent drift in the fading frequency between KO6TZ and W0DHB. It's unlikely that the satellite is speeding up and slowing down in its spin rate, and if it were satellite rotation, the period of the fade should be the same for all stations that are transmitting simultaneously to the satellite (neglecting other effects like nulls from the antenna pattern on the satellite, which may be significant). *If* I'm right, and the frequency of the fading is independent for each uplink station, I would suggest that you are hearing the effect of Faraday rotation. The drift in the frequency of the fading for the different uplink signals would be a result of the differing electron density between the independent stations and the satellite. As the satellite moves, the amount of rotation changes depending on the "thickness" of the ionoosohere, thus causing the indepedendent fading. I haven't done a hardcore signal analysis to extract the exact fading rates, but it sounds like a great student project. It looks like there is even a good research opportunity to dig into the analysis of the HF beacons of the very first satellites and see how they compare to this. Just an alternative hypothesis before you start worrying too much about the sensors...

These have 6 1/2 foot booms and are end mounted. With these antennas comes the H frame stacking framework with mounting brackets. The stacking distance is 3 feet by 4 feet. It also comes with the power divider for the 4 yagis. Everything you need to get the 4 bay system going is there. The antennas are homebrew but very well made, resembling M2 yagis. This system has been used for 70cm EME with good results. The 4 antennas have a common horizontal cross boom to mount in an elevation rotor if desired. I will have these available at Ham Holiday in Oklahoma Cityon Friday and Saturday. I am asking $200 or best reasonable offer for them. I can be reached by email or at 580-591-6885. I can also deliver these to the Dallas/Fort Worth area over the weekend of August 15-16 if you live there and are interested. 73 John AF5CC From kx9x at yahoo.com Mon Jul 20 21:01:08 2015 From: kx9x at yahoo.com (Sean K.)

Message-ID: For those of you who are nostalgic about manned spaceflight, I've just run across a fabulous book: "Marketing The Moon, The selling of the Apollo Lunar Program by David Meerman Scott and Richard Jurek with a forward by Captain Eugene A. Cernan. (130 pgs) MIT Press, 2014 ISBN 978-0-262-02696-3 ------------- To quote from the MIT website: In July 1969, ninety-four percent of American televisions were tuned to coverage of Apollo 11?s mission to the moon. How did space exploration, once the purview of rocket scientists, reach a larger audience than *My Three Sons*? Why did a government program whose standard operating procedure had been secrecy turn its greatest achievement into a communal experience? In* Marketing the Moon*, David Meerman Scott and Richard Jurek tell the story of one of the most successful marketing and public relations campaigns in history: the selling of the Apollo program. Primed by science fiction, magazine articles, and appearances by Wernher von Braun on the ?Tomorrowland" segments of the *Disneyland* prime time television show, Americans were a receptive audience for NASA?s pioneering ?brand journalism." Scott and Jurek describe sophisticated efforts by NASA and its many contractors to market the facts about space travel?through press releases, bylined articles, lavishly detailed background materials, and fully produced radio and television features?rather than push an agenda. American astronauts, who signed exclusive agreements with Life magazine, became the heroic and patriotic faces of the program. And there was some judicious product placement: Hasselblad was the ?first camera on the moon"; Sony cassette recorders and supplies of Tang were on board the capsule; and astronauts were equipped with the Exer-Genie personal exerciser. Everyone wanted a place on the bandwagon. Generously illustrated with vintage photographs, artwork, and advertisements, many never published before, *Marketing the Moon* shows that when Neil Armstrong took that giant leap for mankind, it was a triumph not just for American engineering and rocketry but for American marketing and public relations." ------------------ It's a combination of a coffee table full of great photographs and an engaging, well researched, well annotated, and well written story. Don't miss it... it's well worth the (affordable) price. 73, Eric W3DQ From n8hm at arrl.net Tue Jul 21 23:11:14 2015 From: n8hm at arrl.net (Paul Stoetzer) Date: Tue, 21 Jul 2015 19:11:14 -0400 Subject: [amsat-bb] 73 on 73 Awards #21-#26 Message-ID: Good evening, Several 73 on 73 Awards have been issued since my last update.

At the moment the Russian segment is being used for school contacts as there is no astronaut in the European section with a licence. So two radios, two different locations. There was a high power radio in the Colombus module but it is not working. The handheld is a backup, currently in use. The two sections are as such independent, with co-operation. There are different voltages in different sections which also makes moving equipment from one to another very difficult. The section used depends on the Nationality of the astronaut. SSTV always seems to be Russian, probably due to equipment in that module. Packet is always European, as far as I know.

I've seen that page but didn't glean that reasoning. I dug up an older ARISS posting which hopefully adds a bit more to the good explanation by Dan just a minute ago: --- The "new" radio is actually a Kenwood D710 which is located in the Russian Service module. The Service Module is where the ARISS team performed most of its contacts in the past as it was near the table where all the crew had dinner. Since the first contacts with ARISS in 2000, the ISS has significantly expanded, both in size and in crew size. ARISS has expanded too, with an additional station location in the Columbus module, which is on the other end of ISS (about football field in length). This is where the US, Europe, Japan and Canada conducts most of its experiments and where they spend most of their time. Right now we are using a lower power radio, an Ericsson handheld, in the Columbus module, as it was already on-board ISS (launched in 2000). Our near term plans is to upgrade the Columbus station to a higher power radio (mobile radio class). Keep an eye out for these plans to mature. Note that we are unable to move radios from the Russian segment (Service Module) to the US segment (where the Columbus module is located) as the power systems are different (28V vs 120 V) and certification for the Kenwood radios was only performed for the Russian segment. At the last ARISS International meeting, the delegates agreed with a plan to make sure all future equipment is interoperable and certified across the ISS. This will cost more money and take more time, but should provide more equipment flexibility for ARISS. For now, APRS is using the lower power radio in the Columbus module. I hope this helps explain things. 73, Frank Bauer, KA3HDO ARISS International Chair & AMSAT-NA V.P. for Human Spaceflight Programs -- 73 de JoAnne K9JKM k9jkm at amsat.org AMSAT VP User Services From johnbrier at gmail.com Wed Jul 22 16:13:35 2015 From: johnbrier at gmail.com (John Brier) Date: Wed, 22 Jul 2015 12:13:35 -0400 Subject: [amsat-bb] Is ISS Digipeater not always on for use?

We?d like to show to everyone about SPROUT, and we?d like to ask receiving cooperation to everyone. SPROUT was launched at May 24, 2014 from Tanegashima Space Center in Japan. There are 3 main missions in SPROUT. ?Deployment demonstration of inflatable membrane structure. ?Demonstration of attitude determination and control technology for several kilogram class nano-satellite. ?Upbringing of human resources of a space sector For more information http://sat.aero.cst.nihon-u.ac.jp/sprout-e/ Please see this website. This time, we made a deployment demonstration of inflatable membrane structure. But it's necessary to get a deal of data to get information on a satellite, and it takes time to get one of data only my satellite communication ground station. So when everybody of amsat would do reception cooperation, information on a satellite can be got quickly We'd like to request reception cooperation of everybody of ?amsat? for study promotion. If you wouldn?t mind, please reception cooperation.

That explains the notion I had that I wasn't tracking properly. So, 1200 baud and 1200 shift ... I have been using UISS, I'll try to see if I can decode anything with this. Lately I have really gotten into the digital-satellites. Never interested me before but now I see there is potentially a lot to see on a pass versus listening to my CW on AO-7 on the way-far horizon.

Message-ID: <55B27401.6050406@denstarfarm.us> UO-11 is AFSK. according to one web page about UO-11: "The 145.826 MHz beacon transmits FM Audio Frequency Shift Keying (AFSK) 1200 bps ASCII data." . I am told UO-11 is 1200 baud and 1200 shift. It surely sounds different than the AX.25 I have been listening to. I didn't seem to setup Mixw anywhere correctly during a 5 min slice of the orbit today. Could somebody explain how to set that up please ? 73, -- Bob KD7YZ http://www.qrz.com/db/kd7yz AMSAT LM#901 __._,_.___ ------------------------------------------------------------------------ Posted by: Bob KD7YZ ------------------------------------------------------------------------ Reply via web post ?

Our e-mails have gone unanswered. - Michael, N3UC - Dan, KM4HZJ - James, N3UCC Dave Webb, KB1PVH, sent a tweet earlier this month to @TSKelso at CelesTrak and AO-27 is back in the list. Control operators can now track AO-27 and attempt to load high level code. It is very important amateur radio operators DO NOT USE AO-27, the satellite is in MAINTENANCE MODE ONLY. Attempting to use the satellite or randomly transmitting on the uplink frequencies as the satellite passes nearby does interfere with control operators attempting to upload commands and software. -- Bryan Herbert - KE6ZGP Newhall, CA.

It is an Icom Z1A 2m/70cm HT that does up to 5 watts with the correct battery pack. It does dual receive so you can listen to 2 frequencies at the same time, and can do dual inband receive as well. It works fine and comes with the BP170 battery case, so you can add AA cells to it. I will include 4 recharable AA batteries, which I have no way to charge. Also come with the belt clip, antenna, and wrist strap. You can find the manual on line. The lettering on a couple of the keys is warn, but you get use to their function rather quickly. This is the model where you can remote the top half of the HT to use as a speaker mic, if you can find the remote cable, which I don't have. I am asking $75 plus shipping for it and can take paypal/check/MO. 73 John AF5CC From n8hm at arrl.net Sat Jul 25 23:11:08 2015 From: n8hm at arrl.net (Paul Stoetzer) Date: Sat, 25 Jul 2015 19:11:08 -0400 Subject: [amsat-bb] Potential Phase-3E Opportunity In-Reply-To: <55B3BDE3.20003@charter.net> References: <55B3BDE3.20003@charter.net> Message-ID: Well, nothing is certain, especially when you can't pay your own way. Everyone involved has been careful to present this as a possible opportunity and not something that will definitely happen. According to the presentation this morning, we should know whether this project will move forward by October 1st. It seems like AMSAT is stuck between a rock and a hard place with some here. There has been criticism that the board and officers weren't pursuing opportunities for years because there was never anything published. Now that opportunities have been announced, it seems there will be a ton of critcism if they don't go forward. Unless some very very rich people become big fans of AMSAT, we will always be dependent on finding ways to partner with the government, educational institutions, and private industry in a way that makes sense for them to provide us a service that would cost millions of dollars to purchase on the open market. The bottom line is that years of behind the scenes work is potentially on the verge of paying off big time for the amateur radio community. These opportunities may not materialize, but the relationships developed while pursuing them colan only help to bring more opportunities in the future. 73, Paul, N8HM On Saturday, July 25, 2015, Michael wrote: > It's good news but I'll believe it when I see it.

I find that good because it reduces weight and complexity, and more space for payloads, And yes nothing is certain! :)... I'd rather have a HEO than a GEO, At least you can actually still move your antennas and work diffrent locations rather than a fixed location. And if they are going to move forward they need to make it so the batterys run off the panels when they die. Its quite sad its been sitting in storage for 7 years now, hopefully the goverment will help. 73's KE8AKW, Nick From amsat at n0jy.org Sun Jul 26 02:03:34 2015 From: amsat at n0jy.org (Jerry Buxton) Date: Sat, 25 Jul 2015 21:03:34 -0500 Subject: [amsat-bb] Potential Phase-3E Opportunity In-Reply-To: <850243192.4258114.1437873681679.JavaMail.zimbra@comcast.net> Message-ID: <86ac648f-5a5b-4a07-938e-ecedf886b64e@email.android.com> If WE build it.

We have already programmed all of the ARRL standard radio grams and emergency messages. But there is room for more. So think.... What kind of message would you want to send (that is not included in the existing ones) from your HT out in the wilderness. At a hamfest? or any other HAM Radio event or opportunity. Keep them simple and of the same order of length as the existing ones. The existing ones are listed here: http://nts.ema.arrl.org/node/30 But the implementation cannot include blanks for fill-in like the regular ones. But any sentence that stands alone can work. Just thought I'd open it up. Plenty of RAM and only 1 week before delivery... Serious considerations only." To clarify some thought processess Bob added in a subsequent follow- up, "Well, took a few moments and here are some of my ideas. I just realized I can allow a single digit modifier, so the digit can go from 0 to 8. Demonstrating APRStt at Hamfest Demonstrating APRStt to friends I am on schedule. I may be delayed N hours I may be delayed N days I may be early N hours I May be early N days I may quit early N stops I may go farther N stops We are camping and enjoying it greatly. We are hiking and enjoying it greatly. We are sailing and enjoying it greatly Call me on my cell Call my cell on the hour. Or there can maybe be 1-to-8 different whole word modifiers too.

During their stay, the students work together in teams to assemble a manned mission to Mars, utilizing knowledge gained from guest lecturers and interactive field trips. The Foundation for International Space Education Board of Directors has two head teachers and five team mentors to assist the students in their day-to-day activities. United Space School culminates in a project presentation, in which the students present their final project to a panel of industry experts and the public. Upon successful completion of their final project presentation, the students are awarded a graduation certificate. Participants will ask as many of the following questions as time allows: 1. How has your understanding of the universe changed now that you are seeing it from space? 2. What do you think about the plans of some multi-billion dollar investors to mine raw materials on asteroids and satellites? 3. If you were in an emergency situation inside the ISS where an ammonia leak is quite high and the hatches don't work, what would you propose as escape route to save you and your team, and why? 4. What is the most interesting experiment to perform, and why? 5. Do you see the speed of space travel progressing much further than the point it's at now (within our own solar system)? 6. When you return to Earth what do you think you will miss most about the Space Station? 7. What are your expectations of the manned trip to Mars? 8. Isn't the NanoRacks deployer a cool temperature when it's actually working? 9. How do you maintain a natural sleep pattern aboard the ISS? 10. What were the steps you took to become an astronaut? Do you have any advice for those of us who wish to go into space? 11. What do you think the biggest challenge to the space industry today, besides budget? 12.

The broadcast featured CBS's Walter Cronkite and NBC's Chet Huntley in New York and the BBC's Richard Dimbleby in Brussels. Later that same day the satellite relayed the first telephone call to be transmitted through space. Although it is no longer fully functional, Telstar 1 is still in orbit around Earth. https://youtu.be/xdaHYAReYkg + What does it take to test, build and launch a compact (yet highly sophisticated) satellite into orbit?

We have already programmed all of the ARRL standard radio grams and emergency messages. But there is room for more. So think.... What kind of message would you want to send (that is not included in the existing ones) from your HT out in the wilderness. At a hamfest? or any other HAM Radio event or opportunity. Keep them simple and of the same order of length as the existing ones. The existing ones are listed here: http://nts.ema.arrl.org/node/30 But the implementation cannot include blanks for fill-in like the regular ones. But any sentence that stands alone can work. Just thought I'd open it up. Plenty of RAM and only 1 week before delivery... Serious considerations only." To clarify some thought processess Bob added in a subsequent follow- up, "Well, took a few moments and here are some of my ideas. I just realized I can allow a single digit modifier, so the digit can go from 0 to 8. Demonstrating APRStt at Hamfest Demonstrating APRStt to friends I am on schedule. I may be delayed N hours I may be delayed N days I may be early N hours I May be early N days I may quit early N stops I may go farther N stops We are camping and enjoying it greatly. We are hiking and enjoying it greatly. We are sailing and enjoying it greatly Call me on my cell Call my cell on the hour. Or there can maybe be 1-to-8 different whole word modifiers too.

The contact will be a telebridge between NA1SS and W6SRJ. The scheduled astronaut is Kimiya Yui KG5BPH The contact should be audible over the west 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. The United Space School is the premier educational program hosted by the Foundation for International Space Education (FISE). For two weeks each summer, FISE invites approximately 50 students from 23 different countries to the Clear Lake, Texas area to introduce them to aspects of working in the space sciences. During their stay, the students work together in teams to assemble a manned mission to Mars, utilizing knowledge gained from guest lecturers and interactive field trips. The Foundation for International Space Education Board of Directors has two head teachers and five team mentors to assist the students in their day-to-day activities. United Space School culminates in a project presentation, in which the students present their final project to a panel of industry experts and the public. Upon successful completion of their final project presentation, the students are awarded a graduation certificate. Participants will ask as many of the following questions as time allows: 1. How has your understanding of the universe changed now that you are seeing it from space? 2. What do you think about the plans of some multi-billion dollar investors to mine raw materials on asteroids and satellites? 3.

The broadcast featured CBS's Walter Cronkite and NBC's Chet Huntley in New York and the BBC's Richard Dimbleby in Brussels. Later that same day the satellite relayed the first telephone call to be transmitted through space. Although it is no longer fully functional, Telstar 1 is still in orbit around Earth. https://youtu.be/xdaHYAReYkg + What does it take to test, build and launch a compact (yet highly sophisticated) satellite into orbit?

Even if you send a huge amount of power up, I don't see how it could damage the satellite, by the time it reaches the sat, the power would be so low. Is this only something for the linear birds, does it apply to FM satellites as well? Thanks Skyler KD?WHB -- Skyler Fennell amsatnet.info KD?WHB electricity440 at gmail.com From n8hm at arrl.net Sun Jul 26 15:24:14 2015 From: n8hm at arrl.net (Paul Stoetzer) Date: Sun, 26 Jul 2015 11:24:14 -0400 Subject: [amsat-bb] Why too much uplink power is bad In-Reply-To: References: Message-ID: Hi Skyler, There are two issues: The first issue is the automatic gain control in the satellite passband. Linear transponders only have a limited amount of power available to spread across the 20 kHz - 100 kHz passband, so the gain needs to be limited to keep the transponder output linear. When a very strong signal is in the passband, everyone else's signal is weaker. For example, I can usually receive my own signal (using 5 watts from an FT-817 to an Arrow) about S8 above 5-10 degrees on FO-29. On Field Day, it was tough to get a decent signal even above 40 or 50 degrees because of all the high power stations in the passband. Your signal should be no stronger than the beacon. The second issue is how it could damage the satellite. The issue is when an aging satellite's power system (such as AO-7 or FO-29) can't manage to provide the full power ordinarily needed to run the satellite. In AO-7's case, too strong of a signal can bring the voltages available to the transponder down to a point where it can cause the satellite to switch modes. In FO-29's case, strong signals in the passband while the satellite is in eclipse could cause the battery voltages to drop to a point where the satellite would shut off to preserve the batteries. This doesn't apply to FM satellites, but using a lot of power to dominate the satellite by using the FM capture effect to keep weaker signals out is considered poor practice. Remember that the FCC amateur service regulations require the use of the minimum power necessary to conduct communications. The regulations also require you to not cause harmful interference to other amateur stations. Using excessive power on a linear transponder violates both of those provisions. Also remember that when we're talking about "excessive power" that's ERP, not actual output. Even 500 mW could be excessive power if you're using a huge antenna array and the satellite is right overhead. I have heard stations use the excuse that they are only running 2 watts when called out for pounding the transponder with an excessively strong signal. Well that might be too much, turn it down more. If your radio doesn't allow you to turn the power any lower, you may need to add an attenuator pad to your station. Also, a CW signal is much harder on a linear transponder than an SSB signal because a CW signal at keydown is full power, where a SSB signal only reaches full power on voice peaks. 73, Paul, N8HM On Sun, Jul 26, 2015 at 11:03 AM, Skyler F wrote: > Can someone explain to me why it is a bad thing for the satellite to have > too much uplink power to it? > > Even if you send a huge amount of power up, I don't see how it could damage > the satellite, by the time it reaches the sat, the power would be so low. > > Is this only something for the linear birds, does it apply to FM satellites > as well? > > Thanks > Skyler KD?WHB > > -- > Skyler Fennell > amsatnet.info > KD?WHB > electricity440 at gmail.com > _______________________________________________ > Sent via AMSAT-BB at amsat.org.

There is still some room. Remember, for the sender using DTMF the message and callsign always fits into 16 digits from the DTMF keypad. The format is: CeMMxCCCCCCpppp# Where e is an emergency flag which, along with x, must be 9 if this is a true emergency message otherwise it says "TEST ... " Where MM is the message number (00 to 99) Where x is a numeric modifier for messages with a "_" in them.

What kind of exchange "counts" for satellite contacts? (where counting matters)? Does it really have to be CQ... QSL... and then QSL ...? For the DTMF Voice system, we could have two more messages: " CQ Satellite, my number is *" (the satellite assigns the digit *) " QSL number _, my number is *" (station enters the _ in his reply) Usage would be: A station sends a DTMF uplink message "WB4APR says CQ Satellite my number is X". A responding station sends "W3ADO says QSL number X, my number is Y" Finishing it off with "WB4APR says QSL number Y, my number is X. Another station joins in "W4XYZ says QSL number X, my number is Z and the reply could be "WB4APR says QSL Number Z, my number is X... WB4APR made two valid contacts with XYZ and ADO. In otherwords is that required for an exchange? The number for "My number is *." is assigned sequencially for the pass, so that it is unique. The QSL station always has to enter the number of the matching station to which he is responding. Just a thought. Or does anyone give a hoot about counting satellite "contacts"?

In-Reply-To: <7cabec06b14634a759a83ef584adbef5@mail.gmail.com> References: <7cabec06b14634a759a83ef584adbef5@mail.gmail.com> Message-ID: <55B6310A.20101@coloradosatellite.com> Bob, As I recall that was the only message that I left in DOVE for any period of time. The memory fades but I think I had some other messages loaded for just a couple of minutes while testing and trying to get that one to sound right. I just dug through my hard drive archives from the DOVE days and did not find any other messages. Those test messages would have been transmitted only briefly while over my Colorado QTH. It took a couple of hundred hours to get that message to sound right. Some of that was learning curve, but DOVE voice message creation was a slow, iterative multi-step process of hand entering hex codes representing phonemes strung together to make words, along with other hex codes to change inflection and pitch (like the "down" inflection at the end of the word "space"), then assembling them into 68HC11 op codes. Unfortunately that message was only on DOVE for a few months before it died. I received a call one day that the voice was garbled. I reset the voice hardware and reloaded the hex file that drove it but it never pronounced phoneme strings after that. We presumed at the time that a single event upset or cumulative radiation dose had permanently damaged the voice hardware.

Then we need only the QSL message so that both stations can QSL each others grid!... So the DTMF grid will come down now as: "Grid FM19 from WB4APR QSO number X." A reply DTMF QSL message from someone else will be "W3ADO says QSL QSO number _. Thanks for the contact". Done.

A contact with a satellite does not qualify as a contact for ARRL purposes. A contact through a satellite does. For example, as Bob suggests, you say here I am and the satellite says here I am. That is not a contact as it is not two hams making a contact THROUGH a satellite. We had this same discussion back in the RS robot satellite days in the 90's. If you were lucky enough to get your signal into the RS robot just right, it came back and talked to you and gave you a contact number. But, it was not a two-way contact. If we apply the ARRL Worked All States rules.... "Contacts made through repeaters or any other power relay method cannot be used for WAS credit. A WAS award is available for Satellite contacts. All stations contacted must be ?land-based stations.? Contacts with ships, anchored or otherwise, and aircraft cannot be counted." Then the satellite talking would not count as both stations are not land-based. If we look at the ARRL VUCC rules.... "No contacts through active repeaters are permitted, except for Satellite Awards." Thus, both stations did not operate "through" a satellite, one was the satellite. ARRL DXCC rules are the same... "*6. All contacts*must be made with amateur stations working in the authorized amateur bands or with other stations licensed or authorized to work amateurs. Contacts made through "repeater" devices or any other power relay methods (other than satellites for Satellite DXCC) are not valid for DXCC credit. " It is like the little Sputnik that went up for the 50th anniversary and gave out messages from all over the world. If you copied it, you got a certificate. However, had they added your call sign to the message, you could not have been able to use it for an award (VUCC, WAS, DXCC) because the contact was not through the satellite but with the satellite. Now, I might suggest that we offer an AMSAT award for this satellite or one be sponsored by a group. For AMSAT to offer an award, it must be available to be earned by any ham worldwide and not be a contest. 73...bruce On 7/27/2015 7:48 AM, Robert Bruninga wrote: > Maybe what I really need to know, is whether a grid exchange is required to > constitute a valid satellite contact, or just an exchange of calls? > > > > Bob > > > > *From:* Robert Bruninga [mailto:bruninga at usna.edu] > *Sent:* Sunday, July 26, 2015 4:12 PM > *To:* amsat bb > *Cc:* Robert Bruninga > *Subject:* Re: QIKCOM-2 SPoken Messages > > > > AMSAT Armchair "contact" lawyers: > > Continuing with the DTMF message ideas.

We had been trying to figure out a way to do this and it was actually quite simple as suggested by one of our members. Log into your LOTW account, click on "Your QSOs". Select the station you want to include for your AMSAT award. Click on "Details". Use a screen capture program or Windows Snipping tool and attach that screen shot. The information displayed contains both callsigns, the DXCC entity, the Grid Square, the time/date and mode for the contact. Everything we need for the contact to be accepted. This will make it easier for everyone to submit for AMSAT awards as they do not also have to get a hard copy QSL card for their LOTW contacts. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards 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 n8hm at arrl.net Mon Jul 27 15:02:30 2015 From: n8hm at arrl.net (Paul Stoetzer) Date: Mon, 27 Jul 2015 11:02:30 -0400 Subject: [amsat-bb] EO-80 In-Reply-To: <20150727094854.CLZ40.29159.imail@fed1rmwml108> References: <20150727094854.CLZ40.29159.imail@fed1rmwml108> Message-ID: "A few weeks" was the word in mid-June for the activation of the transponders on EO-79 and EO-80. The presentation at the AMSAT-UK Colloquium shed no further light on the timeline for the activation, other than "soon." Might as well bring the gear as you can always try SO-50 and there seems to be a decent chance that EO-80 will be activated by your final week or two there. 73, Paul, N8HM On Mon, Jul 27, 2015 at 9:48 AM, wrote: > I am travelling to Austria Germany and Northern Italy for 7 weeks and wondered if they have plans to turn on EO-80 in the near future ??

As discussed in the presentation, the need to change the orbit from the initial geosynchronous transfer orbit has always been an obstacle. AO-10 didn't make it to the right orbit, AO-13 made it pretty close to the targeted orbit, but the orbit it ended up in turned out to be unstable, and, of course, AO-40's engine problems severely damaged the satellite. 73, Paul, N8HM On Mon, Jul 27, 2015 at 12:49 PM, Lennart Kieft wrote: > > > Hello All, > > > > It is great news to hear about the opportunities for P3E, > > > Unfortunately > the internet connection on board of the vessel I?m currently on, is not capable > of opening the video. > > I?ve read > on the article that the orbital engine and fuel tank will be removed.

Its probably condensation! This will ALWAYS happen unless it is hermetically sealed and that is near impossible. DUring the day, hot moist air stabilizes inside and outside. At night the cooler temperatures will cause the mostirue inside to condense. Every day the cycle continunes. Water builds up to failured. And that is why such things are placed in at least mildly tmperature controlled environments. Also, do not foget that night-sky radiative cooling of anything that can see the sky will cool below ambient and make condensation even worse.

Like many outdoor preamps. Have a look at picture of these and you?ll see what I am getting at. Moisture comes from 2 places. From precipitation and from the air (condensation). I?ve use the following with great success. First the precipitation. Cover it like a ?hat?. I use a piece of wide PVC or drainage pipe, though a plastic project box will do as well. I seal the top with a cap and leave the bottom open. All cables and connectors must come from the bottom for zero chance of water tricking in through a cable hole on the top or side or through the connectors. Also seal the connectors using some of the new vinyl coax wrap (love this stuff), electrical tape, or coax seal (though the latter can be a bear to cleanly remove later). What you're basically doing is affixing a ?bucket? over the top of your diplexer. Now for condensation. Resist any temptation to seal up every crack and crevice of the diplexer. As long as there is any air inside, you will eventually get condensation due to temp and humidity changes. And it needs a way to get out when that happens. If you cover the bottom of your PVC pipe be sure to leave a weep hole or a small gap perhaps where your cables come in through the bottom so moisture can escape. The only perfect way around the condensation is to have no air at all inside the diplexer housing. Some companies use this approach for outdoor matchboxes and baluns where the whole thing is embedded in a block of epoxy. But before you try taking yours apart and using filler, epoxy, or silicone sealer to fill it up, let me tell you I?ve tried it and my diplexer just didn?t work well afterwards. I suffered added losses and and increased SWR. Perhaps gear just has to be designed for that from the ground up. Hope that helps.

For the DTMF Voice system, we could have two more messages: " CQ Satellite, my number is *" (the satellite assigns the digit *) " QSL number _, my number is *" (station enters the _ in his reply) Usage would be: A station sends a DTMF uplink message "WB4APR says CQ Satellite my number is X". A responding station sends "W3ADO says QSL number X, my number is Y" Finishing it off with "WB4APR says QSL number Y, my number is X. Another station joins in "W4XYZ says QSL number X, my number is Z and the reply could be "WB4APR says QSL Number Z, my number is X... WB4APR made two valid contacts with XYZ and ADO. In otherwords is that required for an exchange? The number for "My number is *." is assigned sequencially for the pass, so that it is unique. The QSL station always has to enter the number of the matching station to which he is responding. Just a thought. Or does anyone give a hoot about counting satellite "contacts"?

Cannot agree with the above enough... You NEVER want to try and seal it up completely; mostly because you can't. (the block of epoxy being the exception) Warm day, heat beating down on it, cool rain comes, case temperature drops quickly, air inside will condense and suck a hole in your weather seal. Now you have moist air trapped inside... no weep holes. It's the same reason you never seal both ends of hollow feedline. Are you thinking of using preamps? Then I want to suggest you try TWO diplexers... one on each feedline before the preamps.

If you make any holes in one, all connectors need to be IP67 rated and used within their specifications for cables. I normally use M20 electrical cable compression glands for the coax, but the connector needs to be fitted after putting through the gland. Always make any holes in the bottom as suggested to stop water running downwards along the cable Two other ideas to stop condensation. One is to totally airtight seal the box and use desiccant. This absorbs moisture in the air, however if air EVER gets in again, the desiccant will soak up completely then re-release the moisture again. The trick is to replace the desiccant every time you open the box. Just keep a spare one in a hot place like on top of a water heater. Some change colour from white to blue to indicate if they are full or not. Heating them for example in an oven removes the moisture and allows them to re-absorb next time. This is a method used regularly in double glazing. The desiccant is placed in the frames of the window normally behind an aluminum edging with holes in it. The inside of the window stays condensation free until there is a break in the outer edge and the desiccant fills up. Another method to stop condensation is to heat the inside of the box continuously. If it is a pre-amp with a voltage regulator then leave it powered up 24/7 and the wasted heat should keep any moisture airborne, although depending on the location you may want resistors or other wasteful heaters to keep the internal temperature always above ambient outside temperature. A similar thing is done in large security cameras to stop the glass from ever fogging up. Similar to a rear window heater on a car. A lot of amateur outdoor equipment use low quality cases and waterproofing. I found a barrel type PL259 connector can be good at stopping one damaged cable from allowing water to feed down a long coax cable and damaging an entire length of cable. Where possible solder or remove all connections/connectors so even a little corrosion won't matter. Using an IP67 case with a transparent lid is a good way to see if water is gathering inside or if condensation is forming. Having an LED on power inputs showing through a clear case is useful to show it is powered up or the heater is working. Cheap kitchen containers are not designed for outdoor use and the plastics crack under UV light.

I wrap it with several turns of bubble wrap, and secure those with tape or cable ties. I then wrap that with heavy duty aluminum foil, several turns, and also secure that. Finally, the top cable is wrapped with several turns of tape sealing the junction of cable and foil to prevent water from running down under the foil. Every 2 years I crack it open to check it, and replace the sealing material. So far it has kept the rain out, and prevented condensation accumulation. 73s, Alan WA4SCA <-----Original Message----- References: <042a01d0c8cd$b08c25d0$11a47170$@net> Message-ID: <049e01d0c92d$9aeed8c0$d0cc8a40$@net> I got a bunch of replies from the group. I thank you all for that. As there doesn't appear to be a weatherproof duplexer available I ended up taking the duplexer apart then sealing all openings airtight with silicone leaving a small hole on the bottom side, the dual lead side. Several suggested some kind of enclosure I didn't want to go that route as it would just make another home for the local flying critters. I was also told that it wasn't water but condensation, I don't think so as both duplexers were completely full of water, you would think both ends would pass water equally but it appears that the connector end as opposed to the lead end is the culprit as the water would get in but then not drain out Another interesting comment was that there is no weatherproof amateur radio equipment suitable to leave outdoors, my Landwehr preamps have been outdoors in the open for over 18 years and their doing fine. When I recently moved them to my new QTH all the markings on them were gone, I had to open one up to positively identify the 2m vs 70cm one. Inside was dry as a bone and no corrosion or rust. :-) Still looking for someone who has successfully got full duplex remote sat ops working....... 73 Jeff kb2m I'm trying to setup a remote sat station and need help with a desence filter. I was using a Diamond MX72-n and was experiencing water intrusion. I then checked the archives and consulted the group and went to the recommended Comet CF-416. Guess what, I'm still getting water into the duplexer. I thought that it was more suited to outdoor service on the recommendation of the group. So, before I take apart one of the duplexers to attempt to waterproof, does anyone know of a duplexer that is designed for outdoor use on the tower? I really don't have the room for a 12 foot + crossboom, so I need to resolve the desence with the duplexer.

The G-1000 DXA is probably (nearly certainly) a DC motor, while that control box expects and AC motor so outputs AC to the motor. All is not lost. Assuming the G-1000 has a potentiometer feedback, you could probably get the control box to turn on some relays with AC coils, which in turn would switch on a DC supply with forward or reverse, and you can keep the same feedback. Another option may be to open the control box, and disconnect the AC for azimuth, and try connect to a separate DC supply. The manuals for the controllers are available on line. If you need me to draw a diagram I can do so. I have used a DC actuator for elevation which is a similar set up to your DC motor for azimuth.

I know you are all volunteers and just doing this in your free time. Second, I should have submitted my images earlier, but I ended up only submitting them on the 28th around 5:00 UTC I downloaded the latest image on the archive, from KE8AKW and the timestamp on the file is from the 25th. The application requires we send links to our images as they appear on the archive, and the deadline is the end of the month, so I am worried it won't be updated in time for me to submit my application. Any insight someone can offer on this? Thank you.

At the moment I don't know how to do an uplink in one mode and the downlink in another. I have an eggbeater, so tracking is not an issue. (I acknowledge that a rotor and a yagi would be better, but I'm working with what I got). Anyway, on this pass I heard nothing, but I was listening in FM. I have heard the CW ID a few times in the past. Guess I was listening on USB those times.

So sorry, but yes. "Houston, we have a small problem..." I hate to say it, but that beacon was IARU coordinated 15 years ago for operation only when PCSAT is over North America, but after 14 years on orbit, we have lost the ability to turn that backup beacon off. PCSAT (now 14 years old) had a backup fail-safe beacon on 144.39 that would activate after any unknown spacecraft reset to give us a backup comm link in case the primary 145.825 channel died. Being on the North American APRS frequency with hundreds of IGates there would always be at least one that would hear this "emergency call home" from PCSAT even though the channel is generally saturated. And it worked. The problem is, that now PCSAT resets on every orbit due to negative power budget and so, on every orbit that beacon comes back on. Even if we did get a command up to reset it, that setting would last only 15 minutes to the next eclipse. We learned our lesson! That was our FIRST amateur satellite and we sure learned NOT to use a "connected-packet-command link" that needs ACKS and Retries and logon passwords just to LOGON before you can even send a SHUTUP command. All our satellites since, operate without the multiple Send, connect, ACK, retry, ACK, command, ACK overhead.... just to get one command understood. Now, only the receiver on the spacecraft has to be functional to command it to silence in a single packet. But too late for PCSAT. We are sorry that we have no good answers. But we hope we can mitigate this instance of "friendly fire" collateral damage so that we don't cause an overall black-eye to amateur radio overall friendly operations? What you may hear will be 2 one-second packets per minute, one at 1200 baud and one at 9600 baud, trying to "call home".

I copied and decoded UO-11 telemetry for years and used it in my Earth Science classes to show students near earth orbit space conditions. When you said "Others here had said UO-11 gives garbage decodes", they actually meant the telemetry you decode from the tones will look fine like what you included, but when you put the values in the formulas to determine the "real" data, that value will be garbage. You can see the date and time are way off in the header of each frame of 7 lines. I sent this on Friday at 2:33 PM EDT. You may have 3 replies ahead of me because I never know how long it finally takes to show up on the BB. I do not see any replies at this time. 73, Rick - WB3CSY On Fri, Jul 31, 2015 at 12:57 PM, Bob KD7YZ wrote: > Once I got the correct Mode-Setting for UO-11, I had no trouble getting > what I think are good decode sets.
