With a 130' run it's lossy. Previously, it was on both UHF and VHF. Replaced the UHF side with LDF4-50A that was dumpster retrevial just after an unnamed blue and white railroad ran their last train out. Much better. With a 130' run was lossy at UHF. Preamp is necessary. On the VHF side, a preamp is usually un-necessary. Rotator loops are 9913F7. Be sure to get the correct N connectors as this has a larger center conductor. Several stranded strands can be trimmed if they are unavailable. On Thu, Mar 31, 2016 at 9:43 PM, w4upd wrote: > I would do like I did to my 9913. This is rather stiff cable.

It worked very well. I did need to replace one length due to a broken center conductor, but that was after years of heavy use. When I rebuild my array, I bought some 9913F (sometimes called 9913F-7 or 9913F7). Same electrical specifications as LMR-400UF, +/-, and noticably more flexible to handle. It has only been up for about 2 years, but so far, so good. I also use it for the mode-L loop to the helix from the hard line feed to the shack.

After taking the arrays down, I was able to reuse some of the 9913. The 9913 I had, had a large solid center conductor. By doing a loose spring type of installation around the mast and boom, there was very little flexing of the cable. This only adds about 2 - 4 foot to the length of the cable. I did this to keep the number of connectors and connections down (especially on 70cm) to reduce cable loses. The more turns (for example maybe 4) the less flexing of the cable will occur. Again, just my 2 cents, but the installation mentioned above was very successful for years. If I ran into any problems it was due to the "known" problem of water getting into the 9913. However, I had little problem with that as well. If the runs are short (less than 50') you could use other methods which requires additional coax fittings and barrel connectors. My goal was to prevent that. I would still recommend a preamp on 70cm at the mast to over come any installation. I found it to be a good addition, especially if we get any HEOs up or for near AOS or LOS operation, trees or weather.

Think of it as a barrel connector with attitude. Yes, putting it at the antenna feed point is better, but unless you're working EME, the practical difference is pretty small. Your luck with 9913 and water ingress is significantly better than mine ever was. I had one 60' run that kept getting worse over time. It got so bad that I drilled a hole in the lower end connector so I could suck out the water until I could find some hardline to replace it. Never used the stuff ever again.

This worked for a while but the UV would wipe out the bottles in a short period of time. After that I used short pieces of SCH 40 PVC with modified end caps for the cable and didn't bother to glue. This worked much better, plus allowed me access to the connectors when needed. I also did this to the rotor connectors.

Well, at least not until I tried to drill another hole into the house next to the first one, and the drill bit went in at an angle and drilled right into the run of 9913. Ouch. I replaced that run with LMR400 and never looked back. It survived for over 10 years, but of course with no motion involved there. ;^) 73 de W0JT EL09vu On Fri, Apr 1, 2016 at 10:45 PM, Greg D wrote: > Hi Reid, > > I understand the desire for minimal use of connectors, but the coupling > between the rigid cable coming from the shack to the rotor, and the flex > cable going to the antenna, is a good place to put a nice little > preamp.

Teachers from Beckman, Irvine, Northwood and Woodbridge high schools developed curriculum for teams of 20 to 25 students from each school to handle the CubeSat mission. Students from Irvine's new Portola High School will be brought into the program when the campus opens in the fall. Students from Rancho San Joaquin Middle School are involved in the project as a STEM feeder program. Organizers of the Irving project are in discussions with a Russian company and have targeted a March 2017 launch date. Irving Public Schools Foundation have granted $150,000 in seed money to launch the project. The schools are planning for three years of missions with a goal of rolling over in perpetuity depending on funding and future support. The project is the brain child of Brent Freeze and Kain Sosa, neighbors in Irvine's Quail Hill subdivision, who have children in the school district. Their goal is to support education that requires specialized science backgrounds and recognize that developing talent could start with STEM programs in local high schools.

Message-ID: <201604030906.u3396D9B029119@mail40c28.carrierzone.com> I can support what Greg stated. I have ten foot of LMR-400UF to go around my az-el system between my Relay/Preamp box and the 4-way divider that feeds my four 2m-eme yagis (21-foot long booms). There is another 18-foot of LMR-400 to each yagi so plenty of coax loss even in an eme array. I figure my loss from antenna to preamp at 0.45 dB. I get away with that much loss because my preamps are 0.1 dB NF vs the typical satellite preamp that has 0.5dB NF. My overall Rx system NF is est. 0.57 dB. on my 6m long-boom yagi I have about 2 turns of LMR-400 that wind around the mast before connecting to my relay/preamp box. This allows enough flex not to break the LMR-400. Ten foot of LMR-400UF would not be significantly more loss so up to 2m it should work fine. The real key to getting good Reception is the preamp at tower top. Most 2m radios have NF of 6 to 10 dB. Transverters are better at about 1.5-2 dB NF. But both benefit with a preamp close to the antenna. I think there is a recent version of Belden 9913 which has solid foam core vs the polyethyline spiral bead with air core that was so susceptible to moisture. I think its called 9913F. But I use LMR-400 as its about the same cost and much better with moisture if you do good sealing at the connectors. 73, Ed - KL7UW ------------ From: Greg D To: w4upd , amsat-bb at amsat.org Subject: Re: [amsat-bb] LMR-400 direct to antenna or no? Hi Reid, I understand the desire for minimal use of connectors, but the coupling between the rigid cable coming from the shack to the rotor, and the flex cable going to the antenna, is a good place to put a nice little preamp. Think of it as a barrel connector with attitude. Yes, putting it at the antenna feed point is better, but unless you're working EME, the practical difference is pretty small. Your luck with 9913 and water ingress is significantly better than mine ever was. I had one 60' run that kept getting worse over time. It got so bad that I drilled a hole in the lower end connector so I could suck out the water until I could find some hardline to replace it. Never used the stuff ever again.

A very strong CW signal can make the transponder useless for others, and in the case of AO-7, cause it to mode jump at certain times of the year. 73, Paul, N8HM On Sunday, April 3, 2016, andy thomas via AMSAT-BB wrote: > Hi > Just sorting out the garden and antennas this Spring day.

For the first and only time in the country's postal history, the United States Post Office Department (since 1971, known as the "U.S. Postal Service") surprised the public with the release of a "secret" stamp celebrating Glenn's successful mission. The 4-cent "Project Mercury" postage stamp was revealed and immediately put on sale in 305 post offices within an hour of Glenn's triumphant return to Earth at 2:43 p.m. EST (1943 GMT) on Feb. 20, 1962. Here's an opportunity for you to own a 50-stamp, complete plate block set of this historic project - suitable for framing for your home or office. Or, in my case, my home office (grin). https://www.32auctions.com/K6LCS There's also arguably the BEST true, full-duplex HTfor the FM birds available there, too - the Icom IC-W32a - WITH a highly desireable early serial number.

The event is scheduled to begin at approximately 18:02 UTC. It is recommended that you start listening approximately 10 minutes before this time.The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and VK4KHZ The contact should be audible over portions of Australia and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Cambridge Bay is a hamlet located on Victoria Island in the Kitikmeot Region of Nunavut, Canada. It is named for Prince Adolphus, Duke of Cambridge, while the Inuinnaqtun name for the area is Iqaluktuttiaq meaning "good fishing place".This ancestral region of Nunavut has been inhabited for 4,000 years. It is rich in archaeological history and blessed with abundant fish, seals, geese, muskoxen and caribou. Kiilinik High School is one of two public schools located in Cambridge Bay, Nunavut. The school has a population of approximately 200 students and provides education from grades 7 to 12. For this event the Primary School will pair up with the high school for the event. Participants will ask as many of the following questions as time allows: 1. Can you change the orbit and speed of Space Station? 2. What is your favorite part of being an astronaut? 3. Is the passage of time on Space Station different than Earth? 4. What time zone do you follow on Space Station and Why? 5. What do you do in your spare time, do you have the internet? 6. What would happen if a crew member was sick while in space? 7. Do you think we will ever travel outside our solar system and is Space Station helping to solve the issues? 8. How is sleep impacted on Space Station and zero Gravity? 9. You are 400 kms up, zero gravity, far away from family, friends, watching the universe and earth go by, looking and pondering into the universe - what is that like? 10. We understand fire burns differently in space, how do you deal with a fire emergency? 11. Are you doing any research related to travel to other worlds like Mars? 12. Was being an astronaut a childhood dream or did you decide later? 13. What were your first impressions when you arrived on the space station and what will you miss from space? 14. How many people can live on space station at one time and for how long with no supply vessel? 15. How advanced or how far and where can we go during the next 100 years in space and space research?

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

Doesn't need to be fancy, I've done it using a RTL-SDR stick and a 1/4 lambda vertical. - Don't stop trying, completing your first QSO is quite a rush Good luck!

In-Reply-To: <11159b0cff94f44cf3ec499e0003c6af@mail.gmail.com> References: <11159b0cff94f44cf3ec499e0003c6af@mail.gmail.com> Message-ID: <1B44A28B-D33A-48CA-AE70-876941B79FB8@comcast.net> Not sure what you want to do. It would help to have more details as sometimes the application drives the trade studies used to choose a device. UHF covers a wide range. I assume that you want to build a class AB or A RF amp for 435 MHz that puts out 30W and costs less than $X? $X is important and the materials that are used to build the amp may well equal or exceed the cost of a transistor when you figure in a enclosure, heatsink, connectors, PCB, and miscellaneous adjunct components. If you need to switch the amp out of line for receive, you need a fairly good relay at those frequencies. If you chose a cheap device that requires a higher voltage, like 24VDC, than the usually available 12V-13.8VDC in the ham shack, you will need to figure in the cost of a power supply. If this is a commercial or semi-commercial application, you should probably figure in the cost of design, assembly, and distribution. You probably know the drill. Also, not sure of your definition of cheap, but $30 isn?t out of line for a good RF UHF transistor. While cheap switching MOSFETS can be used at HF, they usually have too much gate to source capacitance to be useful at UHF, and most need higher voltages than 12.5 - 13V, and some can be unstable at high frequencies. Probably the cheapest and most effective way to generate 30W on 432MHz, is to use a pair of Mitsubishi RD16HHF1 RF MOSFETs at 16W, priced at $4.75 each, lower in quantity. A single RD30HUF1, will put out 30W and costs $23.95 each, again lower in quantity. These will run with good efficiency on 12V-13.8V, are specifically designed for UHF RF applications; unlike the switching MOSFETS. At $45 you can get a Mitsubishi RA30H4045MR 30W RF module that requires a PC board and a few simple external components to make a good amp, but might be cheaper than buying a transistor and components. If you can get by with a Class C amp, there are other design possibilities, and . Again, a lot of these suggestions are based on conjecture as to your actual requirements and applications, but if you give us a better idea of what you want to accomplish, it would be easier to make useful suggestions. - Duffey - KK6MC On Apr 5, 2016, at 7:31 AM, Robert Bruninga wrote: > Asking AMSAT RF experts. > > > > What is the cheapest garden variety UHF Power Transistor good to 450 MHz > and suitable for 20, 30W or more?

On the 20:10utc pass of NO-84 today, I turned on the FM transmitter and shortly after, saw a CW signal on the waterfall. (source unknown) The result was "Zero" copy of the PSK-31 on the down link. This is the same outcome I have experienced using PSK-31 on FO-29 and other linear satellites. One CW signal will disrupt PSK-31 operation. This 'first' experiment brings up the question: does the pulsing of the CW signal disrupt the up link, down link or both ? All prior testing was on LSB/usb satellites. This was on a USB/fm satellite. This test needs to be repeated. Bob KO6TZ And also PSAT, with its 28.120 linear uplink and FM downlink. Although someone has to be transmitting PSK31 for the auto-transponder to come up, any weak CW in the same spectrum should be heard. Although I should not recommend such use, so as not to disrupt normal band plan operations, it is a nice experiment and since the PSK31 transponder is usually never more than about 5% loaded (1 user maybe?) it's a shame not to experiment with it... -----Original Message----- From: Paul Stoetzer Subject: Re: [amsat-bb] CW straight key nowadays > ...the following satellites have linear transponders available for use: FO29 AO-7 AO-73 XW-2A XW-2C XW-2F [PSAT 28.121 up and 435.350 FM down.] Watch your power on CW - especially on AO-7 [and PSAT]. A very strong CW signal can make the transponder useless for others, and in the case of AO-7, cause it to mode jump at certain times of the year. 73, Paul, N8HM On Sunday, April 3, 2016, andy thomas via AMSAT-BB wrote: > Hi > Just sorting out the garden and antennas this Spring day.

They released a new generation of transistors for their mobile radio line a few years ago: http://www.nxp.com/products/rf/rf-power-transistors/rf-mobile-radio:RF-MOBILE-RADIO?cof=0&am=0 They're pretty cheap - target market is public safety radio so cost is a factor. I used the AFT05MS004N on the PA design for ECOSat-II. Richardson RFPD (now owned by Arrow) carries most of the AFT line. You can get official Microwave Office and ADS models for most of the Freescale stuff, assuming you can get a license for one of those. That will significantly cut down on the development time.

All went well until trying to program the pic. I followed Gould Smith's instructions (would have been impossible without them; thanks Gould). Things seem to go OK until it tries to run the picprog software script. It starts, then simply stops at the second line "reading hex file...". It drops to the next line and there it sits (blank with flashing cursor). Hardware: using an XP laptop with a new StarTech FTDI USB-to-serial converter. Could not get the converter to be recognized by either of two WIN 10 laptops, but the old XP machine is fine with it. I have tried all combinations of power on, off, when to plug in, boot up, etc. Same result every time. I did see some cryptic on-line messages of difficulties getting the script to run on anything except an ancient machine with a real live RS232 interface. Surely there is another way.... Humm. Does anyone have any idea on how to make this thing run? Thanks!

Since you are using this list to promote your auction, I felt it was appropriate to question the listing for one of the items in your auction here. One of the items in your auction is a Puxing PX-UV973 2m/70cm FM HT. In the listing for that radio, you say that this "was the first of the recent crop of Chinese HTs to actually perform well in true, full-duplex mode for working V/U FM ham satellites." https://www.32auctions.com/organizations/24686/auctions/29310/auction_items/717906 Huh? Maybe when used with another radio, but certainly not by itself on SO-50 or LilacSat-2, our current V/U FM satellites. Near the end of summer 2013, you ordered and received a PX-UV973. You mentioned this on a mailing list for the PX-UV973 at that time: https://groups.yahoo.com/neo/groups/uv973/conversations/messages/97 When you were working for another importer of the PX-UV973 in late 2013 and early 2014, a few months after you received your first PX-UV973, you were asked about its full-duplex performance on SO-50 in a thread on the eHam satellite forum: http://www.eham.net/ehamforum/smf/index.php/topic,94800.0.html Your response to one question in the thread was: "Is is an excellent performer as a true dual-receive unit ... great second unit to work full-duplex." I think you may have been going for "It is an excellent performer as a true dual-receive unit", which is not the same as an endorsement of this radio's performance for V/U FM satellites. I pointed out in that thread the fact there are many dual-band HTs with dual-receive capabilities, which is different than cross-band full-duplex operation. You later responded to one of my posts in that thread about its full-duplex performance on SO-50 with: "Tentatively, I am not pleased with that mode on the UV973." And now you are saying the PX-UV973 performs well with V/U FM satellites? I bought a PX-UV973 last summer, and tried it with FM satellites over the past few months. Although it could work AO-85 full-duplex, it was the worst performer of the 4 Chinese-made dual-band HTs I tried during the few weeks after AO-85 was launched - and AO-85 is a U/V FM satellite. A recap of those reports I posted on the AMSAT-BB list is available at: http://amsat.org/pipermail/amsat-bb/2015-December/056269.html An article about my tests with these radios working AO-85 full-duplex will appear in the March/April 2016 AMSAT Journal. I have also tried the PX-UV973 with SO-50 and LilacSat-2, and it - like the other 3 Chinese-made HTs I tried with AO-85 last fall - was incapable of working either of those two V/U FM satellites full-duplex. The PX-UV973, like those other 3 Chinese-made dual-band HTs, might do better with V/U FM satellites if the downlinks were much stronger than what we have from SO-50 and LilacSat-2. I'm not sure that AO-27's downlink would have been strong enough to overcome the 70cm receiver desense when transmitting on 2m. It might have taken AO-51's 70cm downlink running at much more than milliwatt power to overcome the 70cm receiver desense when transmitting on 2m. The ISS cross-band repeater was rarely on in V/U mode, and hasn't been on in several years. Maybe this would have been a "satellite" where the PX-UV973 and other radios could work V/U full-duplex successfully, given its higher transmit power than our other FM satellites in the recent past. Unfortunately, with the current crop of V/U FM satellites, the PX-UV973 is just not up to the task of full-duplex operation without the use of a second radio. Its performance may be acceptable for non-satellite work on terrestrial repeaters, as a cross-band repeater when dealing with signals much stronger than satellite downlinks, or as one of two radios for a full- duplex V/U FM satellite station, but that's not what is in the auction listing. Listing it as a radio that performs well with V/U FM satellites isn't accurate - or I am sure we would have heard from you a couple of years ago about the performance of this radio on SO-50. 73.

Hamlib is software which has the actual commands for controlling a radio. However, you'll also need a user interface and Gpredict works well for that. It not only tracks the satellite, it'll control the frequencies as well. Both run on Linux and, I believe, they've been ported to OS X. I use them on a laptop that has openSUSE on it and I've had little difficulty in running my IC-910 with them, at least with the versions I have installed. 73s Bernhard VA6BMJ @ DO33FL From AJ9N at aol.com Fri Apr 8 02:11:58 2016 From: AJ9N at aol.com (AJ9N at aol.com) Date: Thu, 7 Apr 2016 22:11:58 -0400 Subject: [amsat-bb] Upcoming ARISS Contact Schedule as of 2016-04-08 02:00 UTC Message-ID: <117d45.2e3a57d0.44386d6e@aol.com> Upcoming ARISS Contact Schedule as of 2016-04-08 02:00 UTC Quick list of scheduled contacts and events: Kiilinik High School, Cambridge Bay, Nunavut, Canada, telebridge via VK4KHZ The ISS callsign is presently scheduled to be NA1SS The scheduled astronaut is Jeff Williams KD5TVQ Contact was successful: Wed 2016-04-06 18:02:20 UTC 55 deg Valahia University of Targoviste, Targoviste, Romania, direct via The ISS callsign is presently scheduled to be OR4ISS The scheduled astronaut is Jeff Williams KD5TVQ Contact is a go for: Tue 2016-04-12 13:48:06 UTC 79 deg Colegio Santa Rosa, Yerba Buena, Argentina, direct via LU1KCQ The ISS callsign is presently scheduled to be NA1SS The scheduled astronaut is Jeff Williams KD5TVQ Contact is a go for: Wed 2016-04-13 14:02:54 UTC 34 deg USA Science and Engineering Festival, Washington, D.C., telebridge via IK1SLD The ISS callsign is presently scheduled to be OR4ISS The scheduled astronaut is Timothy Peake KG5BVI Contact is a go for: Sat 2016-04-16 18:19:28 UTC 78 deg **************************************************************************** ** The next window to submit a proposal for an upcoming contact is now open.

On the QRZ.com satellite forum, Clint posted that he made a mistake with regard to his auction posting of the Puxing PX-UV973 HT, and that he corrected it. Unfortunately, what he did to "correct" the misstatement in the auction posting was anything but a correction. Clint removed the original auction listing for the Puxing HT, created a new listing, and the new listing still has the same incorrect description. https://www.32auctions.com/organizations/24686/auctions/29310/auction_items/722077 Again, if the PX-UV973 was truly capable of working SO-50 full-duplex, we would have probably heard about it in 2013 after he bought one.

Turns out, I had given a similar talk on the same topic to the same group 6 years ago (2010). But the world has CHANGED (and most of us (and them) have not? except get older).. I began ?How many of you pay about $200/mo for electricity?? Most hands went up ?How many of you went solar since my last talk?? (one hand went up). ?Why not?? I ask. General response was, ?.. it costs too much?? I went on, ?Do the rest of you with the $200/mo electric bill realize you have spent almost $15,000 to the utility since my last talk, and did not also take the $5000 tax credit, so you have wasted over $20,000 and have absolutely nothing to show for it except another $200 a month for the rest of your life, and another $24,000 thrown away every ten years (probably twice that with inflation)?? ?Don?t tell me it costs too much?. It costs too much to do nothing!? ?This other solar guy hardly pays anything now, or the last 6 years or the rest of his life!? Most people in the room said they would probably go solar ?someday?. But now they are starting to realize that every single month they send another $200 to the utility, that is another $200 thrown away? when instead it could have gone for their solar investment which remains EQUITY in their hands, on their roof, or in their yard and which pays back over 10% annual return on the investment every year for the rest of their life. Sorry for the rant. Every AMSAT station needs power. Are you going to continue to burn coal to supply your energy and pay the utility forever, at higher cost, or are you going to do something about it now and start getting free power forever and breath cleaner air. See http://aprs.org/solar-now.html AMSAT TOO: I just looked it up. I gave this talk at the AMSAT/TAPR Dayton Banquet in 2011. In the 5 years since, you (with $200 electric bills) have spent over $12,000 in electric bills and have not taken the over $3600 tax credit either. How many more years are you going to throw away good money every month and do nothing? Sorry, if you have shade, you are out of solar luck, but hug your trees and birds instead! In some states, such as Maryland, you can still invest in community solar where your solar panels will be credited to your bill. Also in Maryland and some other progressive states, if you have some remote land or antenna farm somewhere else, You can install your solar panels there, and get that electric meter to provide 100% credit to your own home bill. Neat! Its called ?virtual-net-metering?. It?s a whole new world of energy changing under your feet?. Every day..

Message-ID: <5707EFD5.6030700@telenet.be> Hello all, I had some minor issues with satpc32 (V12.8c) and I wanted to uninstall and install the program again. So I decided to download the latest program version from the website. I had the latest version but downloaded it anyway to be sure to have a good copy. http://www.dk1tb.de/indexeng.htm It was also V12.8c. But to my surprise that program had some nice improvements. In the satellites menu you can change the window size now to see the complete satellite name. In that same menu there is an extra button : "Display Data" to show more data from the selected satellite. In the "options" menu you can change a setting to update the map (every...seconds) That value changed with me everytime i started the program, now it stays on every 1 sec. To control my sat antennas I use the ServerSDX program delivered with SatPC32. That window also changed (more info on it) Maybe there are more things that have changed, need to find out... Maybe others have that latest version already but I didn't know there were some changes made to the program. 73, Eric. -- Amateur radio station ON4HF Satellite manager UBA Member Amsat-NA #39595 Member Amsat-UK Member Amsat-ON http://www.on4hf.be From normanlizeth at gmail.com Fri Apr 8 17:54:08 2016 From: normanlizeth at gmail.com (Norm n3ykf) Date: Fri, 8 Apr 2016 13:54:08 -0400 Subject: [amsat-bb] Satellites and Solar In-Reply-To: <82ACB41C-4FA2-4AB2-807C-E18D3C8FAB45@gmail.com> References: <5a0883c68cd8531c1fa610e0b4b879bf@mail.gmail.com> <82ACB41C-4FA2-4AB2-807C-E18D3C8FAB45@gmail.com> Message-ID: Newer inverters allow for AC power (like 1.5 kW per inverter) to be drawn without primary power.

After two posts on this list, and posts on a couple of other forums, Clint has finally updated the description of the Puxing PX-UV973 HT in his auction. He removed the references to this radio performing well in full-duplex mode for working V/U FM satellites. That part of the product description now reads: "This model was the first of the recent crop of Chinese HTs to actually perform well in true, full-duplex mode. Truly crossband- repeats, too." (from https://www.32auctions.com/organizations/24686/auctions/29310/auction_items/722077 ) Since I posted my objection to how Clint mischaracterized that radio here on this list, it is only proper to acknowledge that Clint addressed my complaint when he removed the incorrect text from the product description. 73.

That's a problem, Anything they were sure they knew before, is these days almost obsolete a year later. I too had misconceptions all based on my 50 year ham experience with solar (and batteries) for remote digipeaters, etc. My historical background was WRONG on the most basic concepts or modern solar..., hence my sounding "born-again! " That is, FORGET the batteries. The economical revolution in solar is grid-tie. Has nothing to do with batteries (and nothing to do with backup power). Getting rid of the batteries got rid of half the cost and all the lifetime maintenance. It also greatly relaxed the pointing requirements and angles... A true revolution. Solar generation now costs less than a coal plant. Even the Saudi's are building all new energy as solar. Since solar is cheaper than coal or oil, they want to use Solar for all their own energy needs because they can save their oil for export where they can sell it for higher prices. > and there is a misconception that solar can be > used for emergency power... Solar inverter > shuts down once the utility main sense is lost. Yep, same as always. The backup power issue has nothing to do with economical power. Providing emergency power is a totally different function and financial problem no different from what you currently do. Around here the grid is 99.95% reliable. That means, it goes out on average about 4 hours a year. For a 1kW average house load, that is about 60 cents of power loss per year. Adding TEN THOUSAND dollars of "whole house backup battery system" to replace that 60 cents of power per year is not economical... Especially since 5 years later, you will have to replace all those batteries after having only used them maybe 20 hours in 5 years.. No, The answer to "backup" is no different whether one has solar or not. One easy way to do backup, is the same $200 generator and $6 can of gas one might use now. Or plug into the 50kW generator in your Hybrid car, or the 24 kWh battery in your EV, or maybe $400 worth of marine batteries and a $200 inverter form Home depot. All far-far less than a whole house battery system added to solar for 60 cents worth of back up power once a year. AND... the knowledgible Ham who still has 10kW of DC solar power can always find lots of ways to use it even if the grid is down. See http://aprs.org/alternative-energy.html > I have also heard.. rumors that the panels go bad > just after the cost of the system has paid for itself. Solar panels degrade over time. After 25 years they will have lost 20% of their capacity. But, in 25 years I think I can guarantee that one's appliances and electric loads will be 20% more efficient. Hence no change in life style. Just look at the 4-to-1 drop in power needed for lighting in just the last few years. Anyway, yes, they degrade, but less than 1% per year. But they are still producing power. After another 25 years (50 years from now) there will be another 20% loss down to 60% of original power.... but in 50 years you'll be dead or one probably won't need all the power we waste now. And lastly, the cost of 20% more panels to bring your array back up to snuff 25 years from now will cost pennies. Hope that helps. Solar power is cheap, clean power (now costs less than coal.

Bob is right on this one. Long ago solar systems did not last as long as the payback period. (I did the analysis, in the '80s, and again in the '90s.) Economics have changed -- DIY systems can be had for around $2/watt, arrays last longer, and electricity is ever more expensive. If the economy ever recovers, it will get a lot more expensive, at least until the rotating blackouts start. Your biggest obstacle may very well be your local municipality. I know, because I'm reviewing a proposed new zoning ordinance for the rural township where I live, and it will make DIY solar virtually illegal, and commercially installed systems much more expensive. For emergency power, get a generator. When I lived in VA, the performance was like Bob describes, and every time I wanted a generator, I had to ask, "How many times have you been without power for how long?" and didn't. Where I live now (rural, so I can have a tower and antennas) outages are frequent and extended (days) so a natural gas whole-house generator made sense. Went for several years with a "portable" generator (used at Field Day) manually connected when needed. Grid reliability may be changing -- have a friend who lives in Northern VA who got tired of frequent outages long enough to ruin the food so they put in a 25KW whole-house natural gas unit. Good luck! 73, Jim wb4gcs at amsat.org On 4/8/2016 4:23 PM, Robert Bruninga wrote: >> Talking solar with my non Ham friends... > That's a problem, Anything they were sure they knew before, is these days > almost obsolete a year later.

The schedule is shaping up to look like this: Setup and activation on April 11 about 18:25 UTC. Paused April 12 from 12:15 until 14:15 UTC to allow for a school contact with Romania. Paused April 13 from 12:45 until 14:30 UTC to allow for a school contact with Argentina. Deactivation on April 14 at 11:35 UTC. This opportunity should cover most of the world during the operational period.The image transmissions should be on 145.800 MHz and the mode is planned to be PD180. In addition, MAI-75 will be conducting two sessions afterwards. The first one is April 14 from 14:45 until 18:00 UTC. The second session is on April 15 from 14:10 until 19:00 UTC. These times do not cross N. America but will provide opportunities for Europe, Southeast Asia, Australia and S. America. As always, all operations aboard the ISS are subject to change and everyone interested in this activity should be vigilant and patient."

True. And the newer models from SMA with the built-in 15 amp grid-down inverter cost $60 LESS than their previous model of the same 3 kW wattage without the backup (and weighs 30 lbs less!) http://sunelec.com/inverters/inverters-grid-tie/string/sunny-boy-3000tl-us-22-transformerless-grid-tie-inverter.html http://sunelec.com/inverters/inverters-grid-tie/string/sunny-boy-3000w-inverter.html But even when the grid goes down, you still have all that DC power from dozens of solar panels operating at 30VDC each usually connected in series. So, my Armageddon plan is to just tap into my 14 pannel array at the 300 volt point (10 panels) and these days, 300 VDC will power almost every modern electronics piece of equipment AS IS. Just look at your laptop, cell charger, TV, stereo, PC, and most every plugin supply and you will see most have universal supplies operating from 100-to-240VAC and if it is lightweight (has no 60 Hz heavy iron transformer) by definition, that means it is actually a DC/DC switching power supply that can run just as well on DC as AC, since all they do is first rectify to DC before doing all their switching magic. I have plugged in every such supply and device into the 200 VDC of my preius battery and ALL work just fine. In fact, I did a recent test of a half dozen laptop type plug in supplies and they all worked down below 70 volts DC input! Amazing supplies able to deliver full rated output with ANY input from 70 VDC to 330 VDC and 100 VAC to 240 VAC and not know the difference! Remember, a full wave rectified 240 VAC source becomes 330 VDC at the first input capacitor and that is why ANY DC from around 100 volts to over 300 VDC can be used as is on any of these supplies. And you can distribute almost TEN TIMES the power at 300 VDC than at 100 V AC because the current is 1/3rd and hence the I-squared- wire loses are 1/9th over the same wire. CAUTION: Although it is trivial, it is also dangerous if you don?t understand what you are doing. Do not do this at home. A few cautions: 1) MOST of what you really need in a power outage WILL NOT RUN on DC. Furnace, refrigerator, well pump, anything with a 60 Hz motor or transformer 2) Unless you add a snubber circuit to EVERY SWITCH in every device, you will destroy the switch the first time you try to turn the device off on DC. You cannot open a circuit with DC, because the arc will just keep flowing and melt/burn everything in reach. Including your house. 4) NEC requires ALL in-house DC wiring over 50v or so to be in METAL CONDUIT for this reason. 5) Workaround is to UNPLUG quickly and be amazed at the large Arc-Flash. 6) Shock hazard SOoooo... here is my safe suggestion. Keep your eyes open for BODACIOUS surplus DC/DC power supplies from server racks and anything else with huge power supplies. At last night's radio club, a guy showed me one the size of a cigar box that was not only 100Amps at 5 volts but also 30 amps at 12v. And its input was the universal 100-240VAC. Meaning it would run perfectly fine on 300 VDC from my solar array tap. In fact your modern shack DC/DC supply of 25A at 12 v will run from the 100-330 VDC input. Then hook this to a 12v battery to provide some surge capacity and then hook it to a 1500W standard 12v-to-120 VAC 60 cycle inverter from any store (about $150). Bingo, you have 1500W AC with the grid down for $150 (and the big DC/DC suppl you found at the last Hamfest to give you the 12 vdc at high amperage from the HV DC at low amperage from your array.. Oh, also, EVERY HYBRID car (now there are 60 on the market) also has a similar 100 AMP at 12v DC/DC supply to power the accessories in the car from the 200 to 400 VDC car hybrid battery. Get one of these from a junk yard, and there too is a huge source of high power, high voltage DDC/DC supply that can then run conventional 12v-to-120 VAC 60 hz inverters. The ten panel tap at the 300v point in an 8 amps string can supply over 2400 W continuous power to this arrangement. Use two supplies and two inverters to make full use of this string. SO again, just because the grid goes down does not mean your solar array stops producing. It just means it stops producing grid-tie-energy. You still have all that DC to do all kinds of things with... including converting back to AC off grid and/or burning your house down through stupid tricks.

The plan we have is to use a Honda inverter type generator, supplying a 2.2kW APC UPS rack unit which has all the toys plugged into that shuts off the computer automatically when the batteries get below a threshold. That gives me ~40 mins to change over to the generator if I am home, or start the generator when I get home if needed, for radios and fridge. Batteries are not super expensive when bought online. I get mine from here, http://www.tempestbatteries.com/. This is not to run the house, just take the slack between switch over if I am at home for sensitive equipment, or from surge issues from high winds, which we have here...and no... the fridge is not on the UPS. I have pushed a similar design at our radio sites, because there is a small amount of time which site generators start and the UPS do wonders to take up the slack between power loss, and when the generator fully up and switch over. Computers, POE devices like microwave links, AIS receivers, etc, do not like small brownouts and get "confused' which usually resulted in a drive to the site for a power reset. Love the apocalypse ideas...and never thought to feed switchers 300V DC before, but that makes sense, and a darn good idea. For myself, high voltage DC is the last thing I would want to play with in an emergency. -Stephen N.

Regarding using the electric vehicle's battery, I think the safest way is to limit your use to the "Accessory" outlet, pulling no more than its rated 8-amps or so. Plenty to charge your HTs, laptops, cell phones, flashlights, and so forth.

Of course up here in the sub-arctic winter nights are long and summer nights short, so seven months of the year solar provides quite a bit. Doing co-generation with the utility definitely reduces your personal utility costs if you do not need battery banks. I already have a standby gasoline generator (6500w Honda) for power outages. Up here its quite normal to have five or so episodes lasting up to twelve hours/each per year. Very nice to be able to push button for electric start and resume normal life when the power goes out. I can even run my kilowatt amp if I desired. We live in the country so have own well and septic so having backup power keeps everything running. Heat is natural gas but furnace needs power for blower and ignition. I inquired at the local power office when recently paying the bill and they support co-gen so all I need to is do my research and save some pennies. BTW I installed solar panels at work before I retired so have a bit of background. Solar insolation on a cloudy day is only 70% down from a clear day. If enough private solar power were built it probably would offset building some of the utility infrastructure in the future. That might even lower the utilities' cost. Up here one utility installed several large windchargers out on a island which has reliable sustained wind which is supplementing the grid (25Mw I believe). There is ample hydro power so solar might depend on the small private sector to build? 73, Ed - KL7UW Nikiski, AK BP40iq Date: Fri, 8 Apr 2016 17:31:21 -0400 From: To: amsat-bb at amsat.org, Robert Bruninga Subject: Re: [amsat-bb] Satellites and Solar (a) Message-ID: <20160408173121.S6MF2.63087.imail at fed1rmwml301> Content-Type: text/plain; charset=utf-8 And the price of commercial electricity will go up because the power companies will still have to support the infrastructure to supply the full load at night or during cloudy weather yet have it sitting idle when as they say "The Sun is shining."

I have a variable DC power supply I was thinking of either bypassing the battery with or powering via the external dc jack. I don't know what the contact middle contact does though, so I'm hesitant to try that idea. Need to keep the magic smoke in ... Does anyone have experience doing this? Maybe information on the DC jack polarity? The service manual I found online doesn't mention much about powering it up. Any others tips or pointers on the w32a I should know? Thanks for your time.

It is rare to ever hear SO-50 crowded in that part of the world, compared to what you'd hear over North America or Europe. Depending on the passes you are trying, you may not be in the footprints with the North Island in ZL or eastern Australia, where there are some regulars working SO-50 and other satellites. Do you have a memory channel programmed to transmit on 145.850 MHz with the 74.4 Hz PL tone? You may need to turn the satellite on and then make some calls, in case everyone is listening but not trying to activate the satellite's 10-minute timer. Have you tried AO-85 down there? That satellite may be more of a challenge than SO-50 to work, but give it a try if there are some passes compatible with your schedule down there. I was in Australia in 2011, and found that satellite passes were more laid back than here. On the SO-50 passes I worked from locations around Melbourne and Sydney, I was lucky if I heard more than two other stations. This made for nice chats. There was no interest in exchanging grid locators, even though I had my TH-D72A HT and a Garmin GPS receiver to know my grid locator whenever I worked satellite passes (QF22 when around Melbourne, QF56 when in or near Sydney). On the AMSAT-VK Yahoo! group: http://groups.yahoo.com/group/amsatvk/ I have seen reports where there were more stations on some SO-50 passes than just 2 or 3, but for you the footprints will determine if that is possible. You may want to join that list and mention you are in the region, as that might drum up some activity. Good luck, and 73!

Only issue I had was the day I was testing, there was no wind, and the exhaust started to choke the engine intake and sputter a little. That make the UPS unhappy, but output power was constant to the radios. Generator: Honda EU2000i UPS: APC SU2200R3X Generator is new, but the UPS was scrap and was free. Had to buy new batteries, change two voltage divider resistors to bring down the float voltage to where it should be. This generation UPS has issues of cooking the batteries after ~1 year, so I installed two trim pots to take care of that. It has been a few years and the issue has not happened again, nor has the power been out. The best insurance policy against shore power loss is to buy a generator! -Stephen N.

What kind of power will be required on the 5GHz uplink? Does anyone currently make a linear amp or upconverter that can be mounted at the antenna for the 5GHz uplink? Will I be able to use a helix antenna on the uplink or will I be limited to using a dish? Same question with regards to antenna usage for 10GHz downlink. What size dish? With AO-10 and AO-13 I could point my antennas at the satellite and not have to move them for an hour or longer. These new sats will be using microwave frequencies. What kind of realistic expectation do I have of being able to point a dish at the satellite before having to tweak it? Otherwise said, will a rotator be absolutely necessary? Thanks for the info. Looking forward to working the next generation of HEO/GEO sats. 73 Jim Barbre KB7YSY From jbarbre at xmission.com Sat Apr 9 18:23:23 2016 From: jbarbre at xmission.com (Jim Barbre) Date: Sat, 9 Apr 2016 11:23:23 -0700 Subject: [amsat-bb] HEO/GEO analog beacon Message-ID: <5709489B.6040400@xmission.com> Will there be an analog beacon on the upcoming HEO/GEO sats to help with tracking? Will a meter, like the one currently used to position FTA Ku band dishes, work? Thanks. 73 Jim Barbre KB7YSY From tosca005 at umn.edu Sat Apr 9 22:34:10 2016 From: tosca005 at umn.edu (John Toscano) Date: Sat, 9 Apr 2016 17:34:10 -0500 Subject: [amsat-bb] Link budgets for upcoming HEO/GEO sats In-Reply-To: <57093F23.8000501@xmission.com> References: <57093F23.8000501@xmission.com> Message-ID: Estimates suggest aiming for 8 watts of RF and a re-purposed 3-foot-diameter satellite TV dish to be able to get into the bird. It would be nice if only 3 - 4 watts were enough to do the job, because there are inexpensive 3 - 4 watt linear amplifiers designed for First Person Video on radio-controlled "drone" aircraft like this: http://www.ebay.com/itm/262249565979?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT So, time will tell. It is possible that with a slower digital transmission rate the bird might hear well enough for the lesser power. I expect I will try one of these low-power amps, and might even consider driving a pair of them into an appropriate combiner to get twice the power if one by itself does not make the grade. They are small and light, but would require protection from weather. On the other hand, I should have 10 watts available if I need it, once I perform these modification on a much bigger and heavier surplus power amplifier: http://www.g4fre.com/avantekpa.htm (In fact, I have two of these beasts awaiting modification. I think they are much too large and heavy for my tripod-mounted rover station, but one of them might be doable on a fixed station.) It would be hard to equal the gain of a dish by using a helix. Once upon a time, I thought that the helix was the greatest antenna in existence, just make it longer and longer to get outrageous amounts of gain. But the more I investigated the less excited I got about building a humongous helix antenna. (In fact, at one point, I was dreaming about a 2x2 quad array of helices of great length, but I never actually attempted to build one.) On the other hand, I have been amazed by the ability of a scrap-heap satellite TV dish (less than 3 feet in diameter) and a couple of watts of power to make terrestrial 10 GHz SSB QSO's over distances of well over 100 Km, at least when I stopped using a dish that was bent like a Pringles Potato Chip, causing it to lose 10-20 db of its gain! I expect even greater things when an un-damaged dish is pointed up into the sky, away from trees and hills! For the 10 GHz downlink, a possible low-cost scenario might work out to be a direct-to-home satellite TV dish of approximately one meter in diameter, and a PLL-based LNBF, which would mix the 10.5 GHz satellite signal down to the 600 MHz or so range, and the receiving that with some sort of SDR, possibly even a RTL-SDR USB dongle, though perhaps a better SDR might be required. The downlink is going to be DVB-S2x which is NOT the native format of the inexpensive USB dongles. DVB-S2x requires a bit of computation ability on the computer controlling the SDR, especially if the VLSNR (Very Low Signal to Noise Ratio) extensions are needed. It is also possible that we can find (and suitably modify) an inexpensive direct-to-home satellite TV receiver. AMSAT also expects to have a familiar USA company building complete ground station transceivers, but those will likely command a bit of a (well-deserved) premium price. We are actively pursuing a lot of different choices, so stay tuned! >From what I have heard, the bird will be in a geosynchronous orbit, NOT a geostationary orbit, so periodic dish re-positioning of some sort will be necessary. Since the primary payload onto which we get to piggyback is owned by a government agency that likes to keep secrets, an exact proposed orbit is not widely discussed, if at all. So it is hard (for me, at least) to give more specifics at this time. You won't need the horizon-to-zenith-to-horizon pointing ability needed to chase a satellite in Low Earth Orbit, but some positioning in both azimuth and elevation will be needed. High precision will be more valuable than a wide range of pointing directions. In other words, being able to tweak the position by a degree at a time to fine-tune the pointing would be more helpful than being able to move the dish by 30 or 40 degrees. I wish I could be more specific, but I can't at this time. On the other hand, one of the other projects in the works is the NASA-sponsored CubeQuest Challenge, and for that bird you would need to be able to point at any part of the sky where you observe the moon, since the package is going to be headed for lunar orbit! We are trying to make these two birds compatible with the same ground station equipment. Sorry for the vagueness, but I hope it helps a little bit. 73 de W0JT/5, EL09vu On Sat, Apr 9, 2016 at 12:42 PM, Jim Barbre wrote: > Hi all, > > Given that people are currently working on groundstations for the > upcoming HEO/GEO sats, I am in hopes that at least some of the following > questions can be answered. > > What kind of power will be required on the 5GHz uplink? > > Does anyone currently make a linear amp or upconverter that can be mounted > at the antenna for the 5GHz uplink? > > Will I be able to use a helix antenna on the uplink or will I be limited > to using a dish? > > Same question with regards to antenna usage for 10GHz downlink. > > What size dish? > > With AO-10 and AO-13 I could point my antennas at the satellite and not > have to move them for an hour or longer.

In this edition: * ARISS commemorative event (April 11-14) * AMSAT KEPs Redistribution Approved for 2016-2017 * IN81 and IN82 Grid Activation via FM Sats 22 and 24 April * Upcoming Satellite DX * ARISS Contacts and Events * Geostationary / Geosynchronous Amateur Satellite Transponders * AIAA/USU Conference on Small Satellites SB SAT @ AMSAT $ANS-101.01 ANS-101 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 080.01 From AMSAT HQ Kensington, MD. April 10, 2016 To All RADIO AMATEURS BID: $ANS-101.01 ARISS commemorative event (April 11-14) Looks like all the pieces are starting to fall into place for the long awaited SSTV event. The schedule is shaping up to look like this: * Setup and activation on April 11 about 18:25 UTC. * Paused April 12 from 12:15 until 14:15 UTC to allow for a school contact with Romania. * Paused April 13 from 12:45 until 14:30 UTC to allow for a school contact with Argentina. * Deactivation on April 14 at 11:35 UTC. This opportunity should cover most of the world during the operational period.The image transmissions should be on 145.800 MHz and the mode is planned to be PD180. In addition, MAI-75 will be conducting two sessions afterwards. The first one is April 14 from 14:45 until 18:00 UTC. The second session is on April 15 from 14:10 until 19:00 UTC. These times do not cross N. America but will provide opportunities for Europe, Southeast Asia, Australia and S. America. As always, all operations aboard the ISS are subject to change and everyone interested in this activity should be vigilant and patient."

He will be be traveling to these grids during April 22-24. He said he will post his available passes on the Satellite and Space Communications forum at QRZ.com. He will confirm via LoTW. [ANS thanks Felix, EA4GQS for the above information] --------------------------------------------------------------------- Upcoming Satellite DX 4A. MEXICO (Bird Op, Special Event). Operators Ismael/XE1AY and David/XE3DX will be active using the special event callsign 4A1DX between now and June 14th. Activity is to celebrate 11th anniversary of the Grupo DXXE, Mexico's top contest and DX radio club. Operations will be on the satellite, FM only (**SO-50, AO-85 y Lilacsat-2). The QSL Manager is Dick, N7RO, direct or by the Bureau (Make sure your Bureau QSL card is clearly marked via N7RO). Don't send your QSL cards to the Mexican Bureau; they will not be answered because they have no QSLs. They will be uploading the log to LoTW and ClubLog at the end of their operation (June 2016). QSOs with this station are also good for the DXXE Award. ADDED NOTE: The special event callsign 4A1DX is also active on all HF bands using CW, SSB, RTTY, PSK31, JT65 and EME. QSL Manager is also N7RO. See QRZ.com under 4A1DX for more details VP5, TURKS AND CAICOS ISLANDS. John, NW4JG, informs OPDX that he is a resident of the Turks and Caicos Island of Providenciales (NA-002) and has just received the callsign VP5VJG (about a week ago). He mentions, "It is very difficult to get a VP5 callsign. About 5 years working with a tourist temporary permit on island." His also states [edited], "I operate with an Icom 7200 with PW-1 amp. Antennas are Force 12 (40-10m), M2 (6 meters), and a Alpha Delta dipole (160-10 meters). We live on a hill and the antennas are about 150' above the Southern Atlantic Ocean. I also work all Digital modes. Have finally received on the island all the gear for satellite and EME with Yaesu FT736R, 5500 antenna control... etc." IMPORTANT QSL INFO: John, informs OPDX to QSL via John, Graves, 3075 Ohio Street, Miami, FL 33133, when on island. There is no mail from the island. Also, during the summer he will be in a condo in Montreal: QSL via John Graves, 1605 Rue Docteur-Penfield #601, Montreal,QC, Canada H3H 1B2.

I have a W32A and the official Icom wall charger (BC-110A) that came with it is 12 VDC 200 mA output and the plug appears to be 3.3 or 3.4mm OD with a 1.0 mm pin, but verify that. (Most Icom HTs use the same size plug, I believe.) There are simple DC cables, regulated DC cables and noise filtered DC cables. I also have a cig ltr plug that runs to an 'empty' battery pack that connects to the HT. I have more battery/power solutions than I need for mine... (Li-Ion & charger, two AA dry cell packs and 10 NiMH AAs with charger) If you want to contact me off list, I can give you details on what I have and discuss a trade or something. =^) 73, Kevin N4UFO I just received a well loved ic-w32 from ebay. I need to get a new battery and a charger for it though. Both are expected. Before I do, though I'd like to make sure it _actually_ works. I have a variable DC power supply I was thinking of either bypassing the battery with or powering via the external dc jack. I don't know what the contact middle contact does though, so I'm hesitant to try that idea. Need to keep the magic smoke in ... Does anyone have experience doing this? Maybe information on the DC jack polarity? The service manual I found online doesn't mention much about powering it up. Any others tips or pointers on the w32a I should know? Thanks for your time.

That is after a mod to remove an internal pad. Testing done at 5760 MHz. From the HackRF specs, you would need 10-20 dB of gain to drive the amp as output between 4000-6000 MHz is -10 to 0 dBm. I'd probably use a simple MMIC amp for starters. I hope to test the system once my amp arrives in the next week or so. Mike On 4/9/2016 6:54 PM, Jim Barbre wrote: > Thanks John for your responses.

So the bottom line is, thankfully, I am now active on the SATS and have nearly a dozen QSO's in the log..! Following up the comments below, I did a number of things to the stations to finally get working, these included, setting the correct CTCSS tones on the 847, realigning the azimuth on the rotator, it was around 20 degress out - all of which helped....but the biggest impact was the 847, its been in for repair under warrenty twice now, thankfully, so far all looks ok now. Two issues were identified: Frequency and control error on VHF/UHF bands, a couple of chips were replaced, and the killer one was, whenever I switched to SAT mode, the TX output would drop to nearly zero on UHF, whilst on VHF power was also reduced and the CTCSS tones were corrupted.....apparently from the dealer repair I was told both issues were known problems. Thankfully, all now resolved - and up and running....! As I finally get my head round the station / Doppler / SatPC32, I may post a couple more queries....thanks for your tips and advice here...!

I did find one web site listing specs for a visually identical unit: Specification: Model Number: TXPA58002W5 MAX input power: 600mW/27.8dBm Frequency Band: 5-6 GHz Power Supply Voltage: 12-16V Cooling mode: active magnetic fan Lithium battery: 3S 4S Weight: 50 g Power dissipation: 20W Box Size (L * W * H) : 10 * 10 * 4 cm Battery operating time reference: 3S 2200mAh 30 minutes 4S 5200mAh 90 minutes Output connector type: RP-SMA jack Input connector type: RP-SMA plug MAX output power: 2500 mW/+34dbm Temperature: andlt; 80? As you can see, they specify a maximum input of 600mW, but don't specify the gain, so I'm not sure what is the minimum power needed to drive it to full power output. The other interesting thing is that the listings call them a "...Booster Amplifier 3W 4.5W for FPV " but the specs say that the maximum power output is 2.5 watts, so I'm not sure what the "3W 4.5W" refers to... I'm not sure what you mean about a mount/rotator specifically designed for these satellites. There are az/el rotators out there already that should do the job. And there are folks out there who are writing code for Arduino controllers to take over control of Yaesu (and maybe other) rotators...

One other thing I've noticed is that some people using Narrow FM mode might want to try normal deviation to sound better. The Narrow doesn't always help. There is no "one size fits all" on the Narrow/Wide FM debate for AO-85. Use what works best for your station. Some radios like the IC-9100 allow you to set Narrow for either the uplink or downlink separately. 73 Clayton W5PFG On 4/10/2016 09:22, jeffory broughton wrote: > I hear many stations with grossly distorted uplink audio on AO-85. > A- Be sure your keps are up to date. > B- use the newest doppler.sqf files > C- use N.B. tx ,if your rig does not have > It,back off the mic and reduce the mic gain while monitoring your down link > for clean audio. > D- it is possible to have crystal clear audio on AO-85 with a little fine > tuning. > Jeff ,WB8RJY > > jeff broughton > _______________________________________________ > Sent via AMSAT-BB at amsat.org.

In-Reply-To: References: Message-ID: There are similar ground stations on the European side of the pond. The one in Ireland also houses the small 4 foot dish for the HAMTV ISS ground station. Normally the locations are specifically chosen as they are radio quiet, meaning they are far from towns and sources of RF noise. They normally have full backup generators and microwave link towers. Often the main dishes no longer move, and if they do, they are really only suitable for geostationary satellites, and often designed for low frequencies, and as such, obsolete for modern uplinks. Often they do have some obstructions, such as nearby small hills, designed to block direct strong winds, as they are designed to operate in all weathers and the dishes act as a sail. Often these sites end up derelict, as they are so remote they are not of desire to anyone.

I have the Doppler.sqf file set correctly for the 145.825 Packet Robot, and I can see the SatPC32 display show me both the uplink and downlink frequency with logical doppler corrections. However, If the radio is in Satellite mode, it insists on transmitting on 70cm, or if I take it out of satellite mode, only the downlink frequency is actually corrected (it will transmit on the downlink frequency as well).

Cost is quite reasonable for this kind of power at 5-GHz. Note that the DEMI 5670-144 transverter output is +16 dBm (200mw) so one could obtain 2w with drive from one. ERA-5 was common mmic used for this level. Getting 600mw is a bit harder. Most of these run class-A so do dissipate a lot of heat; most of the power becomes heat and not RF. 10-dB RF gain is respectable at microwave. Comment on az-el suitable for 1m dishes at 5 and 10-GHz. The Yaesu satellite rotators do not resolve pointing angle less than 7-1/2 degree so probably not adequate. There are some inexpensive telescope drives that might work at reasonable prices. 73, Ed - KL7UW Date: Sun, 10 Apr 2016 13:24:40 -0500 From: John Toscano To: n1jez at burlingtontelecom.net Cc: AMSAT BB Subject: Re: [amsat-bb] Link budgets for upcoming HEO/GEO sats Looking forward to testing mine too.

Sadly it is not possible at the moment to directly answer your question about possible transponder operations on FUNcube-2 but we hope that it will be possible in the fairly near future. In the meantime, the FC2 transmitter is currently continuously downlinking valid real time telemetry. This provides a good overview of the on board systems and thanks, to the many stations regularly listening (using the normal Dashboard), this data is available on the FUNcube Data Warehouse. Of course we can be looking forward to the launch of the 1U CubeSat - Nayif-1 around the middle of the year. This will also carry a FUNcube transponder and is presently being prepared for insertion into its QuadPack deployer. This operation will take place within the next few days and is in preparation for launch in mid summer on the same launcher as Fox1-C and Fox1-D. 73 Graham G3VZV -----Original Message----- From: J.

The event is scheduled to begin at approximately 13:48 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between OR4ISS and YO9INI. The contact should be audible over Romania and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. The University Valahia of Targoviste (UVT) and its partners are organizing the first Romanian ARISS contact in this historic capital of Wallachia, where ruled Vlad the Impaler, also known as Vlad Dracula. The Faculty of Electrical Engineering, Electronics and Information Technology started its activity in 1995 and it is known for electronics, telecommunications, automation, computer science, electrical engineering and power energy, providing eleven bachelor's, master's and doctoral programs for over 780 students. It has a chapter for IEEE Broadcast Technology Society (Romanian section). We are proud of our students' involvement in several international challenges, conferences and various research events. For the ARISS contact UVT trained 20 pupils aged 12 to 18 who were recruited from different high schools in the county. Their training was offered through the European Space Education and Resource Office ESERO-Romania, which is a collaboration between ESA and national partners (ROSA). The ARISS event was also supported by several companies and associations, namely Vodafone Romania and Start-Tech Association. Participants will ask as many of the following questions as time allows: 1. What are the qualities that define an astronaut? 2. What is the worst and the best part of your job? 3. Have you ever felt the impact of space debris hitting the ISS? 4. What was the most difficult test that you took during your astronaut training? 5. What is an everyday thing which is extremely difficult on ISS? 6. What is the most beautiful thing that you can see from space? 7. Have you ever observed solar radiation affecting ISS radio comm? 8. Is radio comm a passion or a job obligation? 9. What is the most interesting discovery made on ISS using plasma? 10. What's the biggest difference between expectation and reality when living in space? 11. Has food the same taste in space? 12. What is the first thing you will be doing when you come back to Earth? 13. What is your most challenging task on the ISS? 14. How did your know you had a passion for exploration? 15. Do you think spaceflight will be accessible for the masses in the future? 16. Given the chance, would you live exclusively on Earth, or on the ISS? 17. Has space travel changed your life? 18. Is it true that after coming back you shouldn't expose yourself to sunlight? 19. What do you do in your free time? 20. What is the coolest thing that you've done in microgravity?

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

Friday, May 20, 2016 Forum Room #1 Forum Schedule Moderator: Scotty Cowling, WA2DFI 9:15 to 9:25 am Introduction by Steve Bible, N7HPR, TAPR President 9:25 to 9:35 am "Write for QST/QEX" by Kai Siwiak KE4PT, QEX Editor 9:35 to 10:00 am "SatNOGS - A network of open source satellite ground stations". by Corey Shields KB9JHU Abstract: Cubesat operators tend to have few ground stations of their own and rely on amateur operators to help collect telemetry. With cubesat deployments on the rise, more and more data is lost as there are not enough ground stations listening. The SatNOGS Project is a Network of Open Source Satellite Ground Stations, focusing on Low Earth Orbit (LEO) satellites. In this presentation, we introduce SatNOGS as a way to increase the amount of data collected from these satellites and returned to their operators. Learn what the SatNOGS project is, how it works, and what we have planned for the future of amateur radio satellite reception. 10:00 to 10:25 am "HamWAN High Speed IP Radio Network" by Bryan Fields, W9CR Abstract: Presented will be an amateur radio high-speed IP backbone concept (HamWAN) with an emphases on building regional highly available networks. Utilizing the same techniques which enable the Internet, Amateur Radio networks may be built connecting projects to the Internet or other sites. Included will be an update on the regional HamWAN network deployments. 10:25 to 10:50 am "SDR Disrupt" by Chris Testa, KD2BMH Abstract: Tools and techniques for software defined radio continue to evolve at a rapid pace, and we'll go over the landscape and advancements in SDR technologies this past year. Numerous technologies are driving the power-price-performance curve to a new level of efficiency. We'll take a look at John Stephensen, KD6OZH's mesh project (part of TAPR), which helps pave the way for next-generation wireless links. Latest developments in digital voice will also be discussed. 10:50 to 11:15 am "Spectrum Monitoring with Software Defined Radio" by Mike Ossmann, AD0NR Abstract: Having developed HackRF One, the world's lowest cost wideband Software Defined Radio transceiver, the HackRF project continues to produce open source hardware designs for SDR. Find out about our designs in development now and our ideas for future boards that will enable the next generation of SDR enthusiasts.

I have the Doppler.sqf file set correctly for the 145.825 Packet Robot, and I can see the SatPC32 display show me both the uplink and downlink frequency with logical doppler corrections. However, If the radio is in Satellite mode, it insists on transmitting on 70cm, or if I take it out of satellite mode, only the downlink frequency is actually corrected (it will transmit on the downlink frequency as well). Does anyone have any experience using SatPC32 with a Icom radio on the ISS Packet Robot? 73, Bob, WB4SON ------------------------------ Message: 2 Date: Sun, 10 Apr 2016 17:21:14 -0400 From: Dave Webb KB1PVH To: Bob Cc: AMSAT-BB Subject: Re: [amsat-bb] SatPC32 Setup for ISS Packet Message-ID: Content-Type: text/plain; charset=UTF-8 Bob, Use SatPCISS because it puts the radio in same band split mode.

Cost is quite reasonable for this kind of power at 5-GHz. Note that the DEMI 5670-144 transverter output is +16 dBm (200mw) so one could obtain 2w with drive from one. ERA-5 was common mmic used for this level. Getting 600mw is a bit harder. Most of these run class-A so do dissipate a lot of heat; most of the power becomes heat and not RF. 10-dB RF gain is respectable at microwave. Comment on az-el suitable for 1m dishes at 5 and 10-GHz. The Yaesu satellite rotators do not resolve pointing angle less than 7-1/2 degree so probably not adequate. There are some inexpensive telescope drives that might work at reasonable prices. 73, Ed - KL7UW Date: Sun, 10 Apr 2016 13:24:40 -0500 From: John Toscano To: n1jez at burlingtontelecom.net Cc: AMSAT BB Subject: Re: [amsat-bb] Link budgets for upcoming HEO/GEO sats Looking forward to testing mine too.

Sadly it is not possible at the moment to directly answer your question about possible transponder operations on FUNcube-2 but we hope that it will be possible in the fairly near future. In the meantime, the FC2 transmitter is currently continuously downlinking valid real time telemetry. This provides a good overview of the on board systems and thanks, to the many stations regularly listening (using the normal Dashboard), this data is available on the FUNcube Data Warehouse. Of course we can be looking forward to the launch of the 1U CubeSat - Nayif-1 around the middle of the year. This will also carry a FUNcube transponder and is presently being prepared for insertion into its QuadPack deployer. This operation will take place within the next few days and is in preparation for launch in mid summer on the same launcher as Fox1-C and Fox1-D. 73 Graham G3VZV -----Original Message----- From: J.

The event is scheduled to begin at approximately 13:48 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between OR4ISS and YO9INI. The contact should be audible over Romania and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. The University Valahia of Targoviste (UVT) and its partners are organizing the first Romanian ARISS contact in this historic capital of Wallachia, where ruled Vlad the Impaler, also known as Vlad Dracula. The Faculty of Electrical Engineering, Electronics and Information Technology started its activity in 1995 and it is known for electronics, telecommunications, automation, computer science, electrical engineering and power energy, providing eleven bachelor's, master's and doctoral programs for over 780 students. It has a chapter for IEEE Broadcast Technology Society (Romanian section). We are proud of our students' involvement in several international challenges, conferences and various research events. For the ARISS contact UVT trained 20 pupils aged 12 to 18 who were recruited from different high schools in the county. Their training was offered through the European Space Education and Resource Office ESERO-Romania, which is a collaboration between ESA and national partner s (ROSA). The ARISS event was also supported by several companies and associations, namely Vodafone Romania and Start-Tech Association. Participants will ask as many of the following questions as time allows: 1. What are the qualities that define an astronaut? 2. What is the worst and the best part of your job? 3. Have you ever felt the impact of space debris hitting the ISS? 4. What was the most difficult test that you took during your astronaut training? 5. What is an everyday thing which is extremely difficult on ISS? 6. What is the most beautiful thing that you can see from space? 7. Have you ever observed solar radiation affecting ISS radio comm? 8. Is radio comm a passion or a job obligation? 9. What is the most interesting discovery made on ISS using plasma? 10. What's the biggest difference between expectation and reality when living in space? 11. Has food the same taste in space? 12. What is the first thing you will be doing when you come back to Earth? 13. What is your most challenging task on the ISS? 14. How did your know you had a passion for exploration? 15. Do you think spaceflight will be accessible for the masses in the future? 16. Given the chance, would you live exclusively on Earth, or on the ISS? 17. Has space travel changed your life? 18. Is it true that after coming back you shouldn't expose yourself to sunlight? 19. What do you do in your free time? 20. What is the coolest thing that you've done in microgravity?

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

With cubesat deployments on the rise, more and more data is lost as there are not enough ground stations listening. The SatNOGS Project is a Network of Open Source Satellite Ground Stations, focusing on Low Earth Orbit (LEO) satellites. In this presentation, we introduce SatNOGS as a way to increase the amount of data collected from these satellites and returned to their operators. Learn what the SatNOGS project is, how it works, and what we have planned for the future of amateur radio satellite reception. 10:00 to 10:25 am "HamWAN High Speed IP Radio Network" by Bryan Fields, W9CR Abstract: Presented will be an amateur radio high-speed IP backbone concept (HamWAN) with an emphases on building regional highly available networks. Utilizing the same techniques which enable the Internet, Amateur Radio networks may be built connecting projects to the Internet or other sites. Included will be an update on the regional HamWAN network deployments. 10:25 to 10:50 am "SDR Disrupt" by Chris Testa, KD2BMH Abstract: Tools and techniques for software defined radio continue to evolve at a rapid pace, and we'll go over the landscape and advancements in SDR technologies this past year. Numerous technologies are driving the power-price-performance curve to a new level of efficiency. We'll take a look at John Stephensen, KD6OZH's mesh project (part of TAPR), which helps pave the way for next-generation wireless links. Latest developments in digital voice will also be discussed. 10:50 to 11:15 am "Spectrum Monitoring with Software Defined Radio" by Mike Ossmann, AD0NR Abstract: Having developed HackRF One, the world's lowest cost wideband Software Defined Radio transceiver, the HackRF project continues to produce open source hardware designs for SDR. Find out about our designs in development now and our ideas for future boards that will enable the next generation of SDR enthusiasts.

Apparently it IS as difficult as I thought to do it as sea. If I were on the welding team, I would be looking over my shoulder at the rocket, just in case. :) It will be interesting to see what they do once this moves from proof of principle to operational.

So SpaceX just proved everyone wrong. Watching the failures and seeing that each new attempt was closer to success than the prior ones was a study in tenacity. Elon Musk is one heck of a visionary, and he is not afraid to fail very publicly. My father told me that he was sorry for my generation and those that followed. All the important "firsts" had already happened during his lifetime: flight, telephones, radio, TV, computers, spaceflight, etc. We were doomed to just do things better/faster/cheaper. Perhaps he was right, but that process of refinement is what makes things useful.

So one could use a standard transverter with the amp for terrestrial 5-GHz. The satellite ground station will have integrated SDR transceiver for digital modes, being discussed by planning groups. That will also be good news for the average satellite operator since it will eliminate having to scrounge up surplus mw gear and "roll your own". 1m ku-band offset feed dishes are the "norm" for home satellite here in AK so the antenna should not be hard to get. Az-el may require some ingenuity; I'm thinking reuse of small telescope tracking drives which will have necessary finest of pointing. 73, Ed - KL7UW Date: Mon, 11 Apr 2016 06:00:05 -0400 From: Mike Seguin To: amsat-bb at amsat.org Subject: Re: [amsat-bb] Link budgets for upcoming HEO/GEO sats Message-ID: <570B75A5.2090405 at burlingtontelecom.net> Content-Type: text/plain; charset=windows-1252; format=flowed Everyone, This has been tested already.

The event is scheduled to begin at approximately 14:02 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and LU1KCQ. The contact should be audible over portions of Argentina and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Colegio Santa Rosa is a private institution belonging to the "Hermanas Dominicas del Santisimo Nombre de Jesus" congregation. It was created in 1902 and it currently has two campuses, one located in the city centre of San Miguel de Tucum?n and the other one in Yerba Buena. Under the National Educational law in force, the school has kindergarten level (from 3 to 5 years old), primary and secondary level. Since its founding, the school has continued to grow and implement innovations in education, responding to the provisions of the current educational policy, to its own needs and the vision and mission that guides its pastoral pedagogical task. Vision: the school aspires to be an institution of pedagogical pastoral reference , that from a permanent dialogue between tradition and innovation , educate women and men committed to building a more just and fraternal society, in the spirit of the Gospel of Jesus Christ and the Dominican charism traits. Mission: Santa Rosa school, is a Dominican Catholic educational community whose mission is the education of its pupils and students, encouraging alongside the processes of appropriation and generation of new knowledge, the creation of areas of personalization, socialization and maturation in the Christian faith, making a commitment to justice, truth and peace, from the experience of spirituality in Dominican key. Participants will ask as many of the following questions as time allows: 1. At what point did you know you wanted to be an astronaut and how did you achieve that? 2. What were the preparations for Space Station and how long does it take? 3. What qualifications and aptitudes or abilities do you need to take part in the ISS? 4. What were the things that surprised you most living on Space Station? 5. What is your favorite and least favorite activity on Space Station? 6. How did it feel being out on a Spacewalk floating and looking at the Earth? 7. What is it like to live with people from different cultures? 8. With the different cultures and personalities how do you resolve differences? 9. How do you celebrate special dates or holiday occasions? 10. Do you get stressed in space and what do you do to relax? 11. What food do you eat and what are your favorites? 12. What experiments and/or research do you find most interesting? 13. What research did you do in space that has had an impact on life on earth? 14. Have you ever been in an emergency and if so what did you do? 15.

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

But one discussion I heard was talking about designing a dual-band feed horn so a single dish would suffice for both uplink and downlink. They were saying that one band would be vertically polarized, and the other would be horizontally polarized, to help get as much isolation between the two bands as possible. So, we are looking at linear polarization, or more precisely, two different linear polarizations at 90 degrees from one another. The FTA Satellite TV LNB that we are experimenting with for the 10 GHz downlink typically fit into a circular holder on the offset feed arm, and you can simply rotate the whole feedhorn in the holder to vertical, horizontal, or anywhere in between, and then clamp it down. Folks with two dishes to isolate the uplink from the downlink will simply have to use a feedhorn with the correct (TBD) polarization on the 5 GHz uplink. Typically, a homebrewed feedhorn often uses a SMA Coaxial to Waveguide adapter, and the polarization is determined by whether the SMA connector enters the mouth of the waveguide from the top, bottom, or side. So, getting the right polarization is mostly a matter of knowing which band will be polarized which way.

I had two stations going, copying the downlink and recording what I received on both stations. I really need to get set up to use my Elk with more than one radio, or hold two Elks as the ISS passes by. :-) I'm hoping to decode what I copied tonight. I copied about 1/2 of one picture, and all of another. I think there may have been one spot where my SDRplay/HDSDR/Elk setup had something pop up and interfere with the downlink - a truck passed by my yard at that time. 73!

I?ve recently purchased an Elk Log Periodic with hopes of getting onto the FM birds with an HT, and perhaps later on having a crack at the linear transponders using CW, which is my great love. My next step is to acquire one of the inexpensive Chinese handsets, and from the research I?ve carried out, I?m gradually leaning towards the Wouxun models. I?m also totally blind, which will introduce some interesting challenges I?m sure! I do actually have some previous satellite exposure, working UO-14 in 2000 using the satellite gateway of a Toronto repeater system during my month?s stay there. Unfortunately I was side-tracked in 2001, when IRLP really took off. Employment-wise I work for a non-profit organisation, producing audits on Accessible Web Design with assistive technology. Take care, and in spite of the majority of members ostensibly being in North America, perhaps we will hook up on one of the more favourable passes.

The biggest signal you will find is just outside the satellite band.

My AOS on that pass was around 2211 UTC. I barely heard the end of one picture before a break. I copied one picture perfectly, starting at 2215 UTC. It was a 21-degree pass, and the picture I copied was around the middle of the pass. I tweeted the picture already, and will upload it to the ARISS SSTV picture archive shortly. I just got home a little bit ago, my first chance to take my recording from that pass and feed it into RX-SSTV on my tablet. I have been working an earlier shift at my office this week, which worked out perfectly for the afternoon ISS passes.

I, too, heard the tail end of on image and got the next one which like you indicated started just past mid pass. My image had a little noise toward the end, nothing a little polarity twisting on the elk took care of that. Gonna try the 2006 Local pa10 degree pass and then the 2142 lcl 61 degree pass.

My AOS on that pass was around 2211 UTC. I barely heard the end of one picture before a break. I copied one picture perfectly, starting at 2215 UTC. It was a 21-degree pass, and the picture I copied was around the middle of the pass. I tweeted the picture already, and will upload it to the ARISS SSTV picture archive shortly. I just got home a little bit ago, my first chance to take my recording from that pass and feed it into RX-SSTV on my tablet. I have been working an earlier shift at my office this week, which worked out perfectly for the afternoon ISS passes. I might try to catch one evening pass before going to bed tonight, but the 1100 UTC alarm is still hard to accept. Only two more days of that... :-) 73!

That used to be a problem for me in the past, if there was degraded coax cable connecting houses to the cable TV system in the neighborhood. If I transmitted on much of 2m, I would interfere with that cable channel. And I could hear the audio carrier from that channel on my 2m radios. If this is the case, you might hear the audio from that analog cable channel on 149.750 MHz. Thankfully, my current neighborhood doesn't suffer from having some old or compromised cable in the ground between the houses and street (all cable TV and telephone infrastructure is underground around here). And no TVI complaints from the neighbors, when on HF or VHF/UHF. :-) 73!

My arms are tired of holding the Arrow and trying to get over nearby houses so I now have a rotor available and for mounting the arrow on it I am looking at something like the setup pictured in https://www.reddit.com/r/amateurradio/comments/3yip8i/made_a_mount_for_my_arrow_yagi_using_some_pvc/ (from someone who also frequents this list) The 2 meter gamma match (and the split in case of a split-boom Arrow antenna) are indeed near the center of gravity.

The event is scheduled to begin at approximately 18:19 UTC. It is recommended that you start listening approximately 10 minutes before this time.The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between OR4ISS and IK1SLD. The contact should be audible over Italy and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Boys & Girls Clubs of America's vision is ambitious: to assure success is within reach of every young person who enters our doors, with all members on track to graduate high school prepared for their future. For 155 years, BGCA's proven track record of changing and saving kids' lives has been woven into the fabric of what makes our nation great. Today, some 4,200 Clubs serve nearly 4 million kids in nearly every congressional district - from rural communities to urban neighborhoods, from public schools to public housing units, on nearly 500 U.S. military installations, and throughout our country's Native lands. We are redefining the opportunity equation for kids across our country. We are preparing Globally Competitive Graduates through our Great Futures Campaign STEM strategy. Participants will ask as many of the following questions as time allows: 1. What inspired you to become an astronaut? 2. What kind of training did you receive to become an astronaut? What were the hardest parts of it? 3. What do you do in space when you are not working? 4. How is sleeping in space different than sleeping in your bed? I read that you have to be strapped into your bunk during missions. 5. When you get off a boat, sometimes your legs are really wobbly, does this happen when you come home from space? Do you have to readjust to the heaviness of gravity? 6. On Earth, we get regular check-ups to make sure we are healthy and fit for school or athletics. In space, do you monitor your health, like blood pressure? If so, are the machines that are used altered in any way for space flight? 7. We saw online that some of you are conducting research on headaches in space. Are headaches worse in space? Do people get more of them? 8. Do you use 3D printing in space? We have heard that you can print parts to repair things that break. 9. Do things go wrong on the Space Station? What do you do to prevent that from happening? 10. How does new technology modernize today's space flight in comparison to early explorations? Does it change how data is collected, or allow for better quality photographs? 11. How would you compare communication with your family compared to how Apollo astronauts communicated with their families? How has technology changed it? 12. What are some of the problems or challenges with space? travel for someone who is not physically fit? How does NASA ensure you are ready to go into space? 13. We have teams to work on our robots, solar cars, and other projects. How is being on the ISS like being on a team? 14 Do the astronauts ever get mad at each other? 15. We love Space Movies! Which movies are most accurate? What parts are totally unrealistic in most movies? 16. How long does it take to get to Mars and do you think there will be anyone living there, like astronauts or scientists, in our lifetime? 17. What was the scariest thing that has happened to you while on the Space Station or while blasting off? 18. While flying over Washington DC, can you see any of the monuments? 19. When do you think the general public will be able to take a space trip? How soon do you think it might be a normal thing to do? 20. What are some of your concerns for having untrained people fly into space? 21. Have you seen anything that makes you think there might be space aliens? 22. How many days of supplies do you always keep in reserve? 23. If there were a one way mission to Mars, would you try to be on that crew? 24. What did you do as a kid that helped you prepare to be an astronaut? Anything that you now can see was essential?

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org, www.amsat.org, and www.arrl.org.

I?m very happy with the performance on the linear bird?s , but having some issues with AO-85, and SO-50. After getting some bad audio reports on SO-50 yesterday I tried to work the problem out with someone on a local repeater who was familiar with my voice. After a few minutes it became very clear that it was a CTCSS tone issue as simplex performance was excellent. I thought about this a minute and came to the realization that there might be a TX filter in play, and discovered, yes it was set to a default of 150 to 2700. Obliviously not FM values. So just before the last pass of AO-85 I quickly built an FM RPTR filter of 50 to 4k and saved it. It worked a bit better on the pass but I still had obvious issues. Anyone have any ideas what the issue might be? I?m thinking a tone level issue, but after goggling I found issues with CTCSS was too HIGH of a level.

However, others have. There are a couple of factors to tweak. First, cut the primary sample rate back to 96k if you are running 192k. Second, make certain that all the voice buffer sizes are the same. This means on the primary audio tab, and also Buffer Size|Phone on the DSP tab. Try 2048, and if that works, 1024. Probably 96k/2048 would be the place to start as it is most likely to solve the problem. This is the result of trial and error by myself and others and not, on my part, a deep understanding of how PowerSDR works. Not everybody finds the same combination works, so at least part of it involves the computer (and OS version??) you are using. However, it is completely reproducible once you find the right combination. Finally, are you using 435.170 Mhz (435.172 MHz has also been recommended) for the uplink computer tuning?

The frustrating thing is that the advice to use 192k may well have been good for the person who recommended it. (It gets more interesting when you start with digital modes.) Hopefully there will be a combination which will work for you. As for the TX filter, I don't know how much or any effect it has on FM. FM was one of the last features added, and many of the functions which are relevant to SSB or AM are bypassed. If it does effect FM, changing the low frequency cutoff should not effect the CTCSS since that should be injected independent of the voice audio. No promises, and good luck! 73s, Alan WA4SCA <-----Original Message----- << References: Message-ID: Setting up satpc32 at my summer home.

The event is scheduled to begin at approximately 14:56 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between GB1SS and GB4SRC. The contact should be audible over the UK and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. St Richard's Catholic College is a Science Specialist school tucked between the South Downs and the English Channel. We have 1000 pupils on roll between Years 7-11. We provide an inclusive education for Catholic and Christian pupils covering an extended catchment area covering approximately a 30 mile radius. St Richard's was awarded Teaching School status late in 2014 and we are the lead school in the Thrive Alliance, an association of primary schools, secondary schools and a sixth form college as well as lead in the Sussex Science Subject Hub. We are also a strategic partner in the Sussex Maths Hub. St Richards' Science department enjoys a very strong relationship with the University of Sussex (particularly Astronomy & Physics); University of Greenwich (Outreach)and we sit on the STEM Focus Group hosted by the University of Brighton's STEMSussex. We are a keen supporter of STEM events in our region, with particular success at the Annual STEMFest event where we have won prizes at the National Science and Engineering Competition for the last four years, twice through to national competition. STEMSussex have used St Richard's STEM Clubs' provision as an exemplar due to its success in engaging pupils of all abilities across all year groups. The department has also enjoyed high quality Continuous Professional Development engagement in the STEM agenda with involvement in 'Space as a context for teaching science' courses and a future STEM project with the University of Reykjavik in Iceland. We enjoy Space Camp UK, a residential trip with all things "spacy" at the National Space Centre and Duxford. The coordinating teacher, Dr Joolz Durkin, is the curriculum enhancement for science and is also an enthusiastic "Space Ambasador" and has worked with the Tim Peake Primary Project at Parklands Infants Eastbourne, Dallington School in Dallington, Pebsham Primary in Bexhill on Sea and Vinehall School in Heathfield as part of this link up. Participants will ask as many of the following questions as time allows: 1. You have mentioned in an earlier call that you have been sleeping very well on the Space Station. Is that still the case or have you found any cumulative effects after four months in space ? 2. As the ISS hosts astronauts from many different nationalities, what public holidays do the crew observe, if any, and how are they chosen? 3. St Richards and two of our Primary Project Partner school, Dallington and Vinehall are taking part in the RHS 'Rocket Science' Experiment from the Principia Mission. How will the results from this experiment influence future planning for growing similar samples in another planet's gravity? 4. We have seen the preparation with Heston Blumental of an exciting astronaut menu for the mission - does the food taste the same in space as it did on Earth? 5. In a sealed spacecraft like the International Space Station, how is the air quality monitored and controlled? 6. We see the wonderful time lapse images of the ISS orbiting the Earth, but what I like looking at are the stars and making out the constellations. Do you do any astronomical research on the ISS? 7. During the mission you yourself are part of experiments using the British designed MMS Cerebral and Cochlear Fluid Pressure Analyser to collect data for the NASA Fluid Shifts investigation. Which aspect of the self-experimentation has been the most interesting or challenging? 8. Are there any experiments that rely on naked flames on the ISS? If so, how are they carried out and what low gravity precautions are employed? 9. If I oversleep my parents will wake me up - have you overslept on the ISS and had to be woken up by someone?" 10. The distance between Bexhill and Brighton is 31 miles with a journey time by car of nearly 50 minutes. How much time would it take for the ISS to do this trip? 11. What are the greatest challenges of living in space and in retaining a permanent crew on board the ISS? 12. You have tweeted some amazing and beautiful images of the aurora. Have you been able to monitor solar flare or CME activity and correlate to the brightness of the aurora? 13. How does it feel to be able to see all humanity? 14. Is the ISS affected by the Earth's magnetic field? 15. On Sunday you will be joining thousands of others in taking part in the London Marathon. What special routines have you trained for this in space? 16. In the London marathon, runners will have natural cooling as the run - how do you regulate your body temperature in a sealed environment such as the ISS?. 17. We understand you are taking part in the Skin B research on the ISS? Can you share any interesting findings? 18. You have tweeted that having a bacon sandwich and cup of tea on arrival at the ISS was the best welcome possible. What food are you looking forward to on landing? 19. What is special about space suits that help you breathe in space when on an EVA? 20. How smooth was the launch in December?

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org, www.amsat.org, and www.arrl.org.

There isn't one in the middle. Fwiw, some people don't use mounts like me. On the AMSAT NA Facebook group someone said neither armstrong or mount is better than the other, it depends on what suits the user.

The CubeSat Team is a student team of Politecnico di Torino involved in the design and development of small platforms for scientific missions and for testing new technologies. We are guys enthralled by space activities. Undergraduate and graduate students work together with researchers and professors to create a real hands-on experience. ?SPACE IN A CUBE: MISSIONS OF THE FUTURE? is our motto! We believe that small satellites can contribute to a broad set of science goals and space based services. Our CubeSat missions aim at conceiving new scenarios and technologies to serve the scientific community while educating students in the challenging field of aerospace engineering. Our first CubeSat, e-st at r-I, was launched into orbit on February 2012, and the second satellite, e-st at r-II, will be launched next week: the Soyuz launch ST-A VS14 is scheduled on April 22, 2016, at exactly 09:02:13 p.m UTC, from the European spaceport in French Guiana (http://www.arianespace.com/mission/ariane-flight-vs14/ ). It is just one week to launch? it?s time for us to prepare for operations. To celebrate this date, we invite the radio-ham community to support the e-st at r-II mission: participate in the contest to listen out for our CubeSat from orbit! We have prizes for the first to receive the e-st at r-II signal and for the one who will provide us with the higher number of packets received in the first month in orbit! All details of the competition can be found at our official webpage: http://www.cubesatteam-polito.com/operations/radio-amateurs/ Follow the daily updates on our Facebook page (https://www.facebook.com/CubeSatTeam ). Thank you in advance for your help in collecting TLM packets?.. and break a leg!

If you are saying that when CAT is active, you can't twiddle the knob or push the buttons, that's actually expected. When CAT is active, control of the radio is in the hands of the computer software, and the rig is giving it's undivided attention to what is coming in over the serial port.. If you are concerned that the computer software isn't able to control it, that's different. Seeing the CAT light turn on indicates that you do have some communication between PC and the rig. Now you need to verify the serial baud rate (which should be 4800, 8 bits, no parity, and 2 stop bits), and also that the software knows that it's talking to that type of rig. I don't use that particular software, so I can't advise you on the specifics there. If all this checks out, your RS-232 converter might be the problem, but they're pretty simple. Make sure that it's inverting the voltage - a positive voltage on the serial port should be translated to a low TTL level. The circuit I use is a single NPN transistor, collector to the rig, emitter to ground, couple of k ohm resistor between the base and the computer serial port, with a diode between base and ground (cathode to the base). Hope this helps, Greg KO6TH KD4ZGW wrote: > Ok, I am about to pull my hair out. I have done every thing I know how to get Satpc32 to control my Yaesu FT-736r, but no luck.

[ANS thanks AMSAT-NA and Paul, N8HM for the above information] --------------------------------------------------------------------- First-Ever D-STAR Satellite to Launch The first-ever satellite to carry a D-STAR (Digital Smart Technologies for Amateur Radio) Amateur Radio payload into space is expected to launch on April 22 from Guiana. The OUFTI-1 (Orbital Utility For Telecommunication Innovations) CubeSat is one of three CubeSats developed by student teams under the European Space Agency (ESA) Education Office "Fly Your Satellite!" program, which is aimed at training the next generation of aerospace professionals. The satellites arrived in South America on March 25, followed by the student teams a few days later. On March 30 the students pulled the "Remove Before Flight" pins and successfully verified that their CubeSats were ready for launch before replacing the access ports on the P-POD, which will secure the CubeSats prior to and during launch and then will release them into orbit. The next time the students will have contact with their respective CubeSats will be through their spacecraft's communication link, after the CubeSats have been deployed into orbit. Once thermal-optical tape has been applied to the P-POD to shield the CubeSats from extreme thermal radiation during the launch phase, the P-POD will be integrated with the Soyuz launch vehicle. Constructed by students at the University of Liege in Belgium (ULg), OUFTI-1 will be the first satellite to carry an Amateur Radio D-STAR transponder. Developed by the Japan Amateur Radio League, D-STAR enables the simultaneous transmission of voice and digital data as well as call sign-based roaming via the Internet. "The OUFTI-1 D-STAR repeater will be available either as a direct communication repeater between two users, and as an extension of the ULg D-STAR repeater," explains the article "D-STAR digital amateur communications in space with OUFTI-1 CubeSat" by Jonathan Pisane, ON7JPD; Amandine Denis, ON4EYA, and Jacques Verly, ON9CWD, all of ULg. The CubeSat's frequencies are 145.950 MHz (FSK AX.25), and D-STAR down, with an uplink at 435.045 MHz. OUFTI-1 will carry a CW beacon transmitting on 145.980 MHz. The other two CubeSats are from Italy and Denmark. The CubeSat e-st at r-II from the Polytechnic University of Turin, Italy, will demonstrate an attitude control system using measurements of Earth's magnetic field. It will transmit CW and 1.2 k AFSK on 437.485 MHz. AAUSAT4 from the University of Aalborg, Denmark, will operate an automated ocean vessel identification system. It will transmit on 437.425 MHz.

Is that still the case or have you found any cumulative effects after four months in space ? 2. As the ISS hosts astronauts from many different nationalities, what public holidays do the crew observe, if any, and how are they chosen? 3. St Richards and two of our Primary Project Partner school, Dallington and Vinehall are taking part in the RHS 'Rocket Science' Experiment from the Principia Mission. How will the results from this experiment influence future planning for growing similar samples in another planet's gravity? 4. We have seen the preparation with Heston Blumental of an exciting astronaut menu for the mission - does the food taste the same in space as it did on Earth? 5. In a sealed spacecraft like the International Space Station, how is the air quality monitored and controlled? 6. We see the wonderful time lapse images of the ISS orbiting the Earth, but what I like looking at are the stars and making out the constellations. Do you do any astronomical research on the ISS? 7. During the mission you yourself are part of experiments using the British designed MMS Cerebral and Cochlear Fluid Pressure Analyser to collect data for the NASA Fluid Shifts investigation. Which aspect of the self-experimentation has been the most interesting or challenging? 8. Are there any experiments that rely on naked flames on the ISS? If so, how are they carried out and what low gravity precautions are employed? 9. If I oversleep my parents will wake me up - have you overslept on the ISS and had to be woken up by someone?" 10. The distance between Bexhill and Brighton is 31 miles with a journey time by car of nearly 50 minutes. How much time would it take for the ISS to do this trip? 11. What are the greatest challenges of living in space and in retaining a permanent crew on board the ISS? 12. You have tweeted some amazing and beautiful images of the aurora. Have you been able to monitor solar flare or CME activity and correlate to the brightness of the aurora? 13. How does it feel to be able to see all humanity? 14. Is the ISS affected by the Earth's magnetic field? 15. On Sunday you will be joining thousands of others in taking part in the London Marathon. What special routines have you trained for this in space? 16. In the London marathon, runners will have natural cooling as the run - how do you regulate your body temperature in a sealed environment such as the ISS?. 17. We understand you are taking part in the Skin B research on the ISS? Can you share any interesting findings? 18. You have tweeted that having a bacon sandwich and cup of tea on arrival at the ISS was the best welcome possible. What food are you looking forward to on landing? 19. What is special about space suits that help you breathe in space when on an EVA? 20. How smooth was the launch in December?

I attempt to send a direct call to every station that comes up on the heard list. I get very few responses. But, I do occasionally get a response. I got one just a day or two ago, but, unfortunately the log is on my other computer or I'd give the person credit for sending a reply! Thank you station from 4 land! I wonder why a person would set up an auto-beacon. I have to imagine that half of the time, the person isn't even there to see their callsign pop up on the screen. I was going to get on the 0200 pass last night when this thread started but the pass predictions showed it was a 2 degree max elevation for me. That wasn't going to happen with my set up. Anyway, if you see my callsign on an ISS pass, I'm sitting at the keyboard. Give me a shout or send a reply. I even still send out QSL cards if you want one!

Message-ID: Re ISS beacons: Here is the beacon gouge for APRS via ISS APRS was designed for channel sharing using the ALOHA protocol. That is, peak success occurs at around 20% channel capacity. For 1 second packets, that's only 12 packets per minute per digipeater area. This usually means maybe 5 mobiles at a 1 minute rate and 30 other home stations and weather stations, etc at a 10 minute rate using 1 hop and 60 other assets beaconing every 30 minutes when using the maximum of 2 hops. But on ISS, the digi neighborhood covers the entire USA at once! So, it is a travesty that people transmit unattended beacons via the ISS at such high rates causing nothing but interference with those trying to actually operate the pass. See the original APRS-ISS FAQ: http://aprs.org/iss-faq.html It recommends 1 beacon per minute for LIVE keyboarders, 1 beacon per 2 minutes for active special live mobiles engaged in travel or special operations, and one beacon per 5 minutes for unattended status/position reporting. The goal is to optimize the channel for live operators during a pass but for non-moving remote unattended position/status packets to be successful only about once a day (NOT every pass!) on http://ariss.net Bob Bruninga,wb4apr From w0jab at big-river.net Tue Apr 19 16:25:04 2016 From: w0jab at big-river.net (John Becker) Date: Tue, 19 Apr 2016 11:25:04 -0500 Subject: [amsat-bb] ISS Unattended Beacon Theory (UBT) - PROVE ME WRONG!

I was on my way to a fox hunting demo that I was going to do and I figured the ISS pass would be done by the time everyone started to arrive for the demo. Initially I didn't see anything happening and as luck would have it, people started arriving early for the demo I was doing and I got distracted from the pass. Later as I was securing from the demo, I looked at the station heard list on my D-710 and realized that I had succeeded in bouncing a packet off of the ISS during that pass. There were a total of 3 packets listed from that pass, the response to MY beacon, and 2 other packets that were digipeated by the ISS. A live contact would be totally cool, but I was very happy just to get my beacon digipeated by the ISS let alone pick up 2 or 3 others.

You can do a CQ over the ISS digipeater, or just send something like an APRS position packet or a packet with your position and a short comment. If you use APRS messages, you can use them to make QSOs. I just did that tonight for the first time in a few months, working two Texas stations with my TH-D72A HT and Elk log periodic from my driveway. Using the ariss.net wen site, I could see my packets and most of my two QSOs captured by Internet gateways, and a missed QSO with a California station. My TH-D72A will store and display APRS messages, but freeform twxt typed into a terminal program won't be displayed on my HT unless the text is formatted as an APRS message. For example, a station could type this and (if I receive it) have it displayed on my HT's screen and saved as a received APRS message: WD9EWK-9 :hello from (grid, city/state, etc.) On my HT, I'd see the call that sent this message, and the text following the space and colon that trail my call. This makes it easy for stations using the APRS-capable radios, as well as software like UISS, to make QSOs and both sides seeing the QSO happen. It tends to be rapid-fire, since you only have up to 10 minutes in an ISS pass, and there could be a lot of activity coming through the ISS digipeater - especially the further east you go in the continental USA. Passes that only touch the southwestern USA are really easy for the low-power stations (like me) to get through. I do OK on other passes that cover more of the country, even with only 5W. 73!

Keep in mind that you can have a QSO, even if the http://ariss.net site doesn't capture all of the transmissions that make up your QSO. It's just like anything else - if both stations make the exchange and consider it a QSO, it's a QSO. 73!

You can do a CQ over the ISS digipeater, or just send something like an APRS position packet or a packet with your position and a short comment. If you use APRS messages, you can use them to make QSOs. I just did that tonight for the first time in a few months, working two Texas stations with my TH-D72A HT and Elk log periodic from my driveway. Using the ariss.net wen site, I could see my packets and most of my two QSOs captured by Internet gateways, and a missed QSO with a California station. My TH-D72A will store and display APRS messages, but freeform twxt typed into a terminal program won't be displayed on my HT unless the text is formatted as an APRS message. For example, a station could type this and (if I receive it) have it displayed on my HT's screen and saved as a received APRS message: WD9EWK-9 :hello from (grid, city/state, etc.) On my HT, I'd see the call that sent this message, and the text following the space and colon that trail my call. This makes it easy for stations using the APRS-capable radios, as well as software like UISS, to make QSOs and both sides seeing the QSO happen. It tends to be rapid-fire, since you only have up to 10 minutes in an ISS pass, and there could be a lot of activity coming through the ISS digipeater - especially the further east you go in the continental USA. Passes that only touch the southwestern USA are really easy for the low-power stations (like me) to get through. I do OK on other passes that cover more of the country, even with only 5W. 73!

The event is scheduled to begin at approximately 17:32 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and NM5HD. The contact should be audible over New Mexico, USA and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Valley High School (VHS) is one of twelve high schools in the Albuquerque Public School (APS) district. It is physically located at 1505 Candelaria Road N.W., Albuquerque, New Mexico, and our elevation is 4976 feet. Valley HS is one of the "oldest' high schools in Albuquerque, established in the summer of 1954 with their first graduating class of 1955. "Back in the day" students would walk or ride a horse to school as the HS had stables, an active farm, and taught ranching along with the a variety of academic programs. Today, VHS is leading APS in Science Technology Engineering and Mathematics (STEM). Our STEM programs include amateur radio, model rocket (both low and high powered), underwater robotics, radio controlled aircraft, high altitude balloon flights, and unmanned aerial vehicles (small drone helicopters). Currently VHS has 1,371 students enrolled, 150 faculty on staff. Our school colors are Maroon and Gold. Our mascot is the Scandinavian Viking. On Friday, April 22nd 2016, APS along with VHS, West Mesa HS, Garfield MS, John Adams MS, and Carlos Ray ES will make radio contact with the ISS using an Amateur Radio station. The students and staff of all these schools with to express our sincere thanks to NASA team, ISS crew, and ARRL for making this radio contact possible. On behalf of the U.S. Air Force Junior ROTC program, APS, and all our STEM students and staff we welcome this contact with the Land of Enchantment. Participants will ask as many of the following questions as time allows: 1. What is the most interesting or amazing thing you have seen in space? Would you relive the moment if you had the chance? 2. How many times a week do you exercise and what types of exercises do you do to keep your body strong? 3. You have been testing how mice embryos react to micro gravity as they develop. From these results, can a woman have a successful pregnancy in these conditions? 4. How does being in space affect your ability to digest food and absorb nutrition from your meals? Does micro gravity have any effect on peristalsis and the normal function of the digestive system? 5. What kind of medical testing do astronauts go through to be physically and mentally qualified as an astronaut? 6. What types of systems & procedures are available onboard to rescue a crewman who becomes detached from tether while on an extravehicular task? 7. What are the current priorities and scientific studies underway for Mission 45? Are you working on studies that are crucial to the planned Mars missions? 8. What procedures are in place in case of major illness or injury to a crew member while on orbit? Is it possible to evacuate a sick or injured crewman in an emergency? 9. Do you think the work you are doing is worth the risk of being in space? If so, to what end are these efforts. 10. Is there any difference in radiation exposure between time spent in EVA and your time inside the space station? 11. There are lots of debris in orbit from previous missions to space, and space junk is real threat the ISS. What processes or procedures are in place to protect the ISS from space debris? 12. How much of a chance is there for the ISS to get hit with a meteorite, and what would you do if this were to happen? 13. What is the most interesting experiment that you are currently working on? 14. How long can you stay in zero gravity before it affects your body? What kind of effect does this have over time? 15. Once back on earth, how long of an adjustment period is needed for the body to return to normal? PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Visit ARISS on Facebook.

The contact should be audible over the UK and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Wellesley House is a prep school with approx. 140 pupils. Our aim is to open up a world of opportunity for girls and boys aged from 7 to 13. We are primarily a boarding school with about one third day pupils. Our catchment is vast, with international pupils as well as pupils from across the South East. Our ethos is that success follows success, whether in or outside the classroom, and occurs naturally in pupils who are happy and motivated. All pupils are encouraged to push themselves and made to feel secure enough to take risks. The school provided Space outreach for local schools in October 2014 following Science teacher Kerry Sabin-Dawson's attendance at the ESERO-UK Space conference - the Primary Frontier in July 2014 in York. Inspired by the initiatives and resources available she held a Space training session for local primary teachers to encourage them to bring space education into the classroom. Fourteen local schools attended and it was a great success. There was a representative from the Royal Greenwich Observatory, an education liaison officer from the local company Pfizer Ltd, Canterbury STEM ambassador Becky Vincer and John Hislop of the Monkton Stargazers, a local astronomy group. The organiser of the theatre group Spacefund explained how she had written the Team Tim show with the cooperation of Tim Peake, which was promptly booked by some of the schools. Participants will ask as many of the following questions as time allows: 1. Today is International Marconi Day; how do you think Marconi would feel about this radio communication? 2. From space, what evidence can you see that humans are having a negative impact upon planet Earth? 3. We are planting seeds brought back by the Russian cosmonauts at Ursuline. How do you think they will grow? 4. What happens to a compass in Space? 5. It is 400 years today since Shakespeare died. Which Shakespearean quote do you think best describes your mission? 6. What is the biggest lesson you have learned whilst being in Space? (Chartfield) 7. How do you think being in space has changed you? (River) 8. Do bacteria multiply at the same rate in a low gravity environment? (Pluckley) 9. What do you need to do to acclimatize back to the Earth's gravity on your return? (Garlinge) 10. Did you ever dream about becoming an astronaut when you were a child? (St L Junior Acad) 11. What space exploration do you think we will be doing in 200 years? (Smarden) 12. Have you played any jokes on your colleagues on the ISS? Scarlett 13. What is the first thing you are going to do when you get home? (St Lawrence) 14. What was your spacewalk like? Elsie Meades (St Mildreds) 15. What's your favourite experiment to conduct, and why? (Bromstone) 16. What do you do if there is a fire on the ISS? 17. Have you ever seen any other objects go past you in space such as comets or asteroids? (St George's C of E) 18. Will you be visiting schools when you return to Earth? And will you please visit Wellesley House? (again) 19. How is time different in space? 20. Do you get a proxy vote if you are in space?

You can do a CQ over the ISS digipeater, or just send something like an APRS position packet or a packet with your position and a short comment. If you use APRS messages, you can use them to make QSOs. I just did that tonight for the first time in a few months, working two Texas stations with my TH-D72A HT and Elk log periodic from my driveway. Using the ariss.net wen site, I could see my packets and most of my two QSOs captured by Internet gateways, and a missed QSO with a California station. My TH-D72A will store and display APRS messages, but freeform twxt typed into a terminal program won't be displayed on my HT unless the text is formatted as an APRS message. For example, a station could type this and (if I receive it) have it displayed on my HT's screen and saved as a received APRS message: WD9EWK-9 :hello from (grid, city/state, etc.) On my HT, I'd see the call that sent this message, and the text following the space and colon that trail my call. This makes it easy for stations using the APRS-capable radios, as well as software like UISS, to make QSOs and both sides seeing the QSO happen. It tends to be rapid-fire, since you only have up to 10 minutes in an ISS pass, and there could be a lot of activity coming through the ISS digipeater - especially the further east you go in the continental USA. Passes that only touch the southwestern USA are really easy for the low-power stations (like me) to get through. I do OK on other passes that cover more of the country, even with only 5W. 73!

First, a few settings need for the HT to be heard through the ISS or NO-84 packet digipeater... Status Text: I use message number 1 with TX rate 1/1, and I use "WD9EWK and VA7EWK" as the text. The TX rate determines how often this text is transmitted, and 1/1 means everytime your HT transmits your location, this text will also go out with that. You could use something like "CQ de K7TEJ" or something like that to draw attention to yourself. Since I use my HT on both the spaceborne digipeaters and the terrestrial APRS network, I don't normally want to have a CQ call in that text field. Sometimes I will replace the "and VA7EWK" with other text if I am at a hamfest or on a trip, or I'll turn it into something like "WD9EWK and VA7EWK - 2016 World Tour". :-) You can store up to 5 different status text messages, and then select different messages for different situations. You could have a CQ call in one, another message with something like your e-mail address or the repeater you're listening to in another, etc. I just use the first status text message, and change it as needed. TX Beacon: Method is Auto, Initial Interval is 1 minute. Packet Path: Type is Others, PATH is ARISS - this will work for the ISS and NO-84 when its 145.825 MHz digipeater is on, and then you can change the Type value to New-N when you are using the HT on the terrestrial APRS network instead of a spaceborne digipeater. You can either rely on the HT to beacon at that interval you set in the TX Beacon value, or you can press F followed by BCON (the 6 key) to send a beacon on demand. Or press BCON to remove BCON from the display, and then press BCON again to reenable the HT's beacon. An alternative to using the Status Text and TX Beacon to make your CQ calls would be to use an APRS message sent to ALL, and then type in a CQ call like "CQ de K7TEJ". You could just put something like "K7TEJ looking for a call", hoping a live operator in the footprint will pick up on something different coming from the digipeater. APRS messages are normally sent out once a minute over a 5-minute period, or you can go into the MSG (press the 4 key) menu and force an APRS message to be retransmitted on demand. This might be useful, if you see your HT transmit but don't see something like "My Message" or "My Message via ... " to indicate your HT heard the message being retransmitted by the spaceborne digipeater. I don't worry about an explicit CQ call when I work these digipeaters. I transmit my location and status text to show up on the digipeater, and then try to send APRS messages to other call signs I see on my HT's screen. I updated the instructions I have on my QRZ.com page on how I work the ISS and NO-84 digipeaters, asking stations to contact me via APRS messages when they see WD9EWK-9. Otherwise, freeform text sent from another station isn't shown or stored on the HT - just the call sign. Hope that helps. 73!

Message-ID: <20160422001802.FBCF.63087B45@msd.biglobe.ne.jp> I have been trying for weeks to set up a system to decode telemetry packets from EO-79 (QB50P1) without success. As I am new at dealing with data from satellites that is not already handled by a dedicated program such as FUNCube Dashboard, which handles Doppler tracking and packet decoding all by itself, I'm still kind of lost as to how all the required components are supposed to come together. If I can figure out EO-79, goes my thinking, then I can go on to tackling other BPSK 1200 baud birds such as the XW-2 constellation. I will list what I'm doing below; if someone can please give me a sanity check it would be greatly appreciated. - Receiver: FUNCube Dongle Pro+, SDR# outputting to a virtual audio cable. - SATPC32 tracking EO-79, correcting for Doppler, and controlling SDR#. - AGW Packet Engine set up with "Sound Card" TNC (the other end of the virtual audio cable), dual port, 1200 baud for each channel. - AGW Online KISS set up to connect to the Packet Engine. WINSock remote port 8000. - Soundmodem by UZ7HO on the same port 8000 and listening to SDR#, which is set for USB, 4kHz bandwidth. SATPC32 is keeping the packet traces in the center of the 4kHz passband, and I can see the traces appearing in the waterfall in Soundmodem. The modems in Soundmodem (2 channels) are set for BPSK 1200 baud, and the reticules match up exactly with the traces I can see in the waterfall. And Soundmodem refuses to decode a single #$%&ing thing. There is an occasional "" that shows up in the list, and Online KISS will show a bunch of garbage, but this mostly occurs when there is nothing in the waterfall at all. Several sites have said that I'm to connect something to something else using virtual serial ports, but none of them have really given me a straight answer as to where to connect what to what. What am I doing wrong here? Any advice would be ridiculously appreciated. 73 -- J.

If no one is available to "talk" it is not a problem for those that decide to run unattended stations. It is a perception problem by those that expect that on every ISS pass lots of folks just wait for quick preprogrammed or live UISS messages and "QSOs". At least the unattended stations keep the system in use because not to many other folks do. So lets increase the numbers of operators, have AMSAT or someone create an award or something.

I suppose the main problem I'm having is, I'm giving Soundmodem something to decode (I can see the trace in its waterfall) but it's not responding to any of it. I indeed have the "non-AX25 filter" unselected (it is not selected as default). There were some other things in my Soundmodem settings that did not agree with the instructions for DeorbitSail, that may have messed it up, so I'll try again this morning during the next pass. -- J.

When I actually fed it a signal, it didn't respond. So perhaps I've got Soundmodem set wrong. Non-AX25 filter is off, but maybe it's something else. I've looked at the DeorbitSail page so I'll see if my settings match what's there. Thanks! Will report back. -- J.

I'm continuing to experiment by myself on this subject of receiving telemetry data using an SDR dongle and software. I've appreciated all the bits of information offered by the stations who are already up and running. One thing I'm finding with software packet reception is that the software "modem" or software "TNC" (i.e.: soundmodem) seems to expect packets with a good checksum. Just a single bit-flip and I don't have data. My approach at the moment is toward improving my downlink and then I'll see how many more packets I'll find useful. -- 73 de JoAnne K9JKM k9jkm at amsat.org From the2belo at msd.biglobe.ne.jp Thu Apr 21 22:56:34 2016 From: the2belo at msd.biglobe.ne.jp (J.

Just a single bit-flip and I don't have data. In soundmodem, I had "Bits Recovery" set to "SINGLE" initially, while the DeorbitSail page seems to suggest it's more properly set to "NONE". Not sure if that's significant, but your comment about flipped bits made me suspect this. Anything's worth trying once. -- J.

The last bit of the last byte of the destination callsing (or digipeater) field should always be 1 in order to indicate the end of the destination field, but some implementations keep the bit as 0. This is the reason UZ7HO's soundmodem says NON-AX25 frame. Soundmodem does pass the frame to the KISS interface but any decoding software must be careful during the processing of the destination callsign (by assuming there are no digipeaters). Comparing the performance of the 1200 bps BPSK FUNcube-1 FEC encoding with cubesats using AX.25 1200 bps BPSK makes me wander why in this day and age we still use AX.25 for satellite links. 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 appreciated all of the great responses. In the end, I decided to go with the Elk because I found it on eBay and could save some money. The pvc tubing the previous owner used is difficult to turn and I'd like to correct that. I tried Googling to see if simply sanding the inner pipe a bit would help but I didn't get any results on that search. What have you done to make it so that the tubing is a easy to adjust from horizontal to vertical but still is tight enough not to shift on its own?

All of them use UI packets since they are the most efficient (all data in one packet): 1) APRS user message contacts (texting and QSOs) 2) Remote position and status reporting of ham travelers beyond range of the terrestrial network 3) Remote sensor data experiments (ocean buoys or WX data projects) Generally, I have learned that trying to criticize how others use ham radio is a dead end. So instead we try to nudge them towards proper operating practice such as the guidelines on how to use the ISS digipeater: http://aprs.org/iss-faq.html The recommendations have always been: * live operators use a beacon rate of 1 beacon per minute and live QSO packets as required. * Remote travelers (live) should set one packet every 2 minutes (live and moving). * For non-moving travelers and unattended data sources, we recommend one packet every 5 minutes. These rates can show good success for a dozen live users, a half dozen live mobiles and nearly 2 dozen unattended beacons per pass and this is about the average load. Though people would see higher suggess if we could get those dead-woods to cut back their rates. Yes, it is sad that some people transmit unattended beacons via the ISS at 1 minute rates. So what we need to encourage those unattended stations to cut back to one packet every 5 minutes. At that rate, their load is insignificant but they have a good chance of showing up on the heard log ( http://ariss.net) once a day and they exercise and demonstrate the utility of the channel for remote Amateur Radio Applications. So It would seem OK for a few policeman to look for 1 minute unattended beacons and contact them to read the above FAQ page as their responsibility for using the channel.

Minutes for the C5 VHF/UHF/Microwave committee are now available. Some 70 delegates from over 20 Member Societies discussed a wide range of issues in the VHF/UHF/Microwave, HF and EMC Committees. Recommendations from the meeting will be considered by the Region 1 Executive Committee at its meeting in early May 2016. If approved by the EC, these recommendations will become interim Region 1 policy until the next General Conference in 2017, at which time all Societies present will have the opportunity to ratify the proposals. Among the key items in the minutes are: 4.1. Report of satellite coordinator C5_04 Graham Shirville G3VZV presented the report of satellite coordinator. G3VZV emphasized that the frequency coordination between the three Regions has to be improved for avoiding interference incidents like PC-Sat and some of the XW2 satellites. Due to current reports from MS about some observations of harmful interference, RSGB is asked to prepare a statement for publishing to inform MS and members how to take care. C5 chairman is asked to bring up the issue on EC meeting, because further AC action is required. 5.2. Band Planning 5 GHz: C5_10 VIE16_C5_Rec_06: To correct the satellite segment the table in chapter 4.9 by deleting ?5790?, inserting ?5830? and adding the footnote: ?Any wideband system shall protect narrowband applications?. 6.1.

The educational opportunity will use excess performance aboard rockets launching to space to carry the tiny student-made craft made of science and technology experiments. ?Universities pioneered cubesat development, and there is a growing need for launch access and availability,? said Tory Bruno, ULA president and CEO. ?Our goal is to eventually add university cubesat slots to nearly every Atlas and Vulcan Centaur launch ? with potential for 100 rides per year.? Cubesats are baselined at 10 cm x 10 cm x 10 cm (4 inches x 4 inches x 4 inches) and approximately 1.3 kg (3 lbs). The craft are housed in a box-like Aft Bulkhead Carrier on the Centaur upper stage, next to the RL10C-1 engine, and ejected from the dispenser into orbit. ULA has successfully launched 55 cubesats through the company?s 106 flights to date. Those opportunities were via National Reconnaissance Office, Air Force and NASA initiatives. Now, ULA is giving the miniature hitchhiker payloads free rides on Atlas 5 boosters and the future Vulcan rocket now in development to debut in 2019. The company is the first launch provider to make free cubesat flight opportunities available on its own. ?ULA?s cubesat program revolutionizes access to space for these payloads while ensuring that the next generation of rocket scientists and space entrepreneurs has the opportunity to continue driving on- orbit innovation,? Bruno said. The competitive program is available to all U.S. accredited colleges and universities. They are encouraged to partner with K-12 schools to further expand science, technology, engineering and math (STEM) education. The deadline to apply is June 1. The winning cubesats will be announced later this summer. The selection committee will look at a proposal?s mission objectives in science and STEM, outreach plans for their local community, technical requirements and the likelihood of meeting the development schedule. Safety to the flight?s primary payload and ensuring the cubesat will not threaten or do any harm to the mission will be judged, too. Each application will face the following criteria: * Technical Requirements ? 25% * Mission Objective ? 25% * Outreach Component ? 25% * Proposal Credibility ? 15% * Quality of Proposal ? 10% Six cubesat launch slots are available in this first round of the program, each payload sized at ?1U? in cubesat-speak, for two Atlas 5 missions. The first launch will likely be a geosychronous transfer orbit mission targeted for mid-2017. The second flight, also to GTO, is planned for mid-2018.

Digital Forum, moderated by Scotty Cowling, WA2DFI, on Friday, May 20, at 9:15 AM. Among the presentions will be ?SatNOGS ? A network of open source satellite ground stations,? by Corey Shields, KB9JHU. CubeSat operators tend to have few ground stations of their own and rely on radio amateurs to help collect telemetry. The SatNOGS Project is a Network of Open Source Satellite Ground Stations, focusing on Low Earth Orbit (LEO) satellites. Shields will introduce SatNOGS as a way to increase the amount of data collected and reported from these CubeSats. Bryan Fields, W9CR, will present ?HamWAN High-Speed IP Radio Network,? an Amateur Radio high-speed IP backbone concept that uses the same techniques enabling the Internet. The topic of a presentation by Chris Testa, KD2BMH, will be ?SDR Disrupt.? It will review the landscape and advancements in SDR technologies over the past year, as numerous technologies are driving the power-price-performance curve to a new level of efficiency. Latest developments in digital voice will also be discussed. ?Spectrum Monitoring with Software Defined Radio,? by Mike Ossmann, AD0NR, will follow.

The SSTV transmissions marked the 15th anniversary (in 2015) of continuous Amateur Radio operations on the International Space Station. The first ISS crew conducted its inaugural ham radio contact from NA1SS in November 2000, and the first ARISS school/group contact took place the following month. Since then more than 1000 ARISS school/group contacts have been completed. Images received from the ISS have been posted on the gallery website. Anyone who received SSTV images from the ISS also may post them there. The SSTV transmissions were in PD180 format. Additional ?MAI-75 Experiment? SSTV transmissions took place on April 14 and April 15, and these have been posted as well. The commemorative SSTV images showed a few of the radio amateurs who have served aboard the ISS.

From Space! It is time to start listening to space. To celebrate the upcoming launch of the three Fly Your Satellite! student-built CubeSats into low Earth orbit, ESA?s Education office challenges the amateur radio community to listen out for the tiny satellites. The first three radio amateurs to send a recorded signal from either AAUSAT4, E-st at r-II or OUFTI-1 will receive a prize from ESA's Education Office. The satellites will be launched on 22 April onboard the Soyuz VS-14 flight from the European Spaceport in Kourou, French Guiana. Together with CNES? Microscope scientific satellite, they will be auxiliary payloads in the launch of ESA?s Earth observation satellite Sentinel- 1B, the main passenger on this flight. Soon after being deployed into their final orbit, the CubeSats will begin transmitting signals to Earth that can be picked up by anyone with common amateur radio equipment. ESA challenges anyone to record the signal and send it to cubesats at esa.int, and to the CubeSat team. For each CubeSat, the first email received for which the signal is confirmed to belong to the CubeSat will be awarded with the following prizes: ESA Fly Your Satellite! poster ESA Education goodie bag Scale 1:1 3D printed model of a CubeSat Radio Contact Information: Please consult the following links to obtain specific information for radio contact for each of the three CubeSats.

The event is scheduled to begin at approximately 12:02 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between GB1SS and GB1DHS. The contact should be audible over the UK and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. The Derby High School is a state comprehensive school (11-16 with 855 pupils 2015-16) situated in the town of Bury. The school is co-educational and is proud to be a community school supporting the diverse population of Bury and Radcliffe. 50% of students reside in an area within the top 20% of socio-economic deprivation nationally. The proportion of students who are disadvantaged and supported through the pupil premium is significantly high when compared with most schools. The proportion of students from minority ethnic backgrounds is well above average. The percentage of students who progress to post-16 studies is high. The school opened in 1958 and in 2003 became the first Science and Arts Specialist College in the country. The school motto: Excellence, Tradition and Imagination embodies all that we strive to achieve. We are committed to offering a first class academic education with excellent vocational opportunities and preparation for the world of work. Sport is a strength and all our students learn how to 'live well'; to cook, eat healthily and be physically active. Personal, moral, cultural and social education is crucial to the life of our school. Citizenship and ethical education take centre stage in our school. We seek to equip our children and the wider community, not only to live in the future world, but to shape that future world and create a better tomorrow. We are proud to be the face of modern democratic Britain. Our values are enshrined in the 7 R's: Respectful, Responsible, Reasonable, ready, Resourceful, Resilient and Right Impression The enrichment and engagement opportunities on offer to pupils at The Derby would probably not be bettered anywhere. From humble beginnings in 2002, the program of events and activities has grown from a single educational visit to over 50 activities on offer year on year to all pupils regardless of ability. The success of our program has in turn led to national recognition. In 2012 Mr Paul Kerr won an Institute of Physics Teacher Award for excellence in teaching and in recognition for the outstanding commitment to developing an extensive enrichment program. In 2013 the Science Department won the national TES Award for Educational Excellence in Science, and in 2014 was commended in the Science category at The Education Business Awards. In 2015 Mr Paul Kerr was also a finalist at The STEMNET Awards in the category of STEM Leadership. Participants will ask as many of the following questions as time allows: 1.

I have collected there more than 1000 recordings of various satellite and space objects. I am still searching for various recordings of Amateur Radio Satellites, especially for Fuji-OSCAR-12 and UoSAT-OSCAR-15. If you have old tapes or cassettes with recordings of Ham Radio Satellites I will be happy to digitize them. Many thanks in advance for any contributions to the "Sounds from Space" collections.

It was nice to see you on the 1553 UTC ISS pass earlier this morning. Even though you said some packets came in through your local APRS network, the ariss.net web site clearly shows packets from me to you, and from you to me, through the ISS digipeater. The later pass around 1722 UTC had a good amount of live keyboard activity. I worked K7TEJ across town from me in the other Phoenix-area grid DM33, KK6QMS in California, and W5PFG in Texas.

So yes the signal is to weak. After persevering for a couple of passes, one (1) packet was juuuuuuust strong enough to decode! http://i.imgur.com/IlpPiql.png So mark that as my first successful reception of QB50p1. Now that I finally know that I'm doing everything else right, this weekend I'll load the laptop and the Arrow into the truck and go out into the field for some high-gain tracking.

I have upgraded my equipment with a new computer W7 still using NOVA tracking software. My old system P4 with WXP and the par port AEA ST-1 worked fine for many years. So I have the LVB calibrated just fine. Whatever I move the rotor to, the display on the LVB shows the same. The software almaost works with the LVB but is off sometimes by maybe 15 degrees on AZ only. Elev seems to be OK. It also changes depending on the sat or the direction the ants are pointing. Another odd part is that the NOVA shows the correct readings, but the small rotor screen is off. I am wondering if it is the selection of rotor interface in the setup. I find the only one to work is the Easy Comm, but I kinda thought that maybe the Yaesu GS-232 was the one to use...... If anyone has any ideas maybe email me direct. -- Bill Booth VE3NXK Sundridge ON, Canada 79.23.37 W x 45.46.18 N FN05ns Visit my weather WebCam at http://www.almaguin.com/wxcurrent/weather.html Organ and Tissue Donation - The Gift of Life Talk to your family.

There was a CW signal at a moment but as I was in NBFM mode and the time needed to switch to CW or SSB the signal was gone, I just see it on the spectrogram. On the next pass, orbit number 6 around 0720 UTC no CW was heard here, only short digital transmissions. Unfortunately, absolutly no signal received from the E-st at r-II bird (437.485 MHz)... and I did not try OUFTI-1 as I was busy on 70 cm band. 73+++ Jean-Pierre F5YG On 26/04/2016 07:41, GW1FKY--- via AMSAT-BB wrote: > According to ESA, Sentinel-1B lifted off on a Soyuz rocket, flight VS14, > from Europe?s Spaceport in Korou, French Guiana on 25 April 2016 at 21:02 GMT > (23:02 CEST). > > The three CubeSats, each measuring just 0?10?11 cm, piggybacked a ride on > Soyuz are: OUFTI-1 from the University of Liege, Belgium, _e-st at r-II_ > (mailto:e-st at r-II) from the Polytechnic of Turin, Italy, and AAUSat-4 from > Aalborg University, Denmark.

However I have just monitored on a good high pass between 0933 - 0937 hrs GMT. I heard data bursts from AAUSAT -2 and they were very strong even with my simple "ELK" antenna and tracking set up. I was trying to also monitor _e-st at r11_ (mailto:e-st at r11) but did not hear anything either. May have missed of course with having to change back and forward to AAUSAT- 2. Also monitoring OUFTI-1 but again nothing heard but I cannot be sure, I was expecting the beacon to be on 145.980 Mhz. Hoping that the delays with the launch have not caused any problems for the teams. Trust all goes well and good luck with the decoding.

It was easy. Just put a radiant space heater on the other side to heat the wall. Then after an hour or so, use an IR camera to view the wall. You can see the studs and anything else that is inconsistent inside the wall. Then I happened to glance with the IR camera at the wall where I had the 1500 W electric heater plugged in, and I could CLEARLY see the wiring in 3D. By moving the camera around I could see the hot wire in 3D and not only see where it was, but how deep or, along which wall in the pocket it was located. I then went on an exploration mission in my basement to see hotspots in my entire electrical system. It was an amazing color display liken to XMAS. Then I noticed a large, unusually bright spot from the basement looking up at the kitchen floor. I was concerned, since it should have been a part of open floor and there should not be any heat source there unless it was an electrical problem beneath the floor. I ran upstairs only to find a cat, sleeping on a thick rug, on a ceramic tile, on a ?? underlayment, on top of an OAK floor, on top of ?? tongue and groove subfloor. That?s seeing a cat through 3? of solid wood, ceramic and a rug. Just laying there burning up cat food. I think these cameras are under $500 and even have APPS on cell phones that can do it? You wont be able to see though metal, but through anything else, maybe so. In fact, to perfectly mark the hazy images where I wanted to drill the hole to the stud, I used a small 1? square of aluminum foil. It has low emissivity and always appears DARK against anything else that is warm behind it. But also, notice that the aluminum foil is not only low-E, but it is also IR REFLECTIVE. So it can look very hot (98.6F) if you happen to be standing where the aluminum can reflect your body heat.

I worked K8II, WB8RJY, KC4LE, and WN9Q. The transponder worked as well as all of the other XW-2s. Nice to finally hear this one on and make some QSOs on it. I've now made QSOs on all six of the XW-2 satellites. If you haven't worked any of the XW-2 satellites yet, I encourage you all to do so. While they are in low orbits (around 530 km), they are very strong, sensitive, and frequency stable. The evening passes are at a convenient time and I know several hams who work them fine with eggbeaters or dual band verticals. No matter how compromised your VHF/UHF setup may be, you should try it out on these satellites, you may be surprised how well you can work them. 73, Paul, N8HM On Tue, Apr 26, 2016 at 4:53 PM, Pedro Dutra Sousa wrote: > Confirmed in the Azores.

No, looks like only perhaps 1 kHz lower, around 145.979 MHz. 73 !

On Friday (29 April) afternoon through midday Sunday (1 May), I will be part of the AMSAT presence at the ARRL Nevada State Convention in Las Vegas. The convention will take place at the Eastside Cannery Casino-Hotel in Las Vegas. This hotel is located along Boulder Highway at Harmon Avenue, north of Tropicana Avenue and east of the I-515 freeway in Las Vegas. More information about the convention is available at: http://nvcon.org/ During the convention, I will have WD9EWK on the air for demonstrations of satellite operating. If you hear WD9EWK on, please call and be a part of the demonstrations. I will try to post details of the planned satellite demonstrations here on the AMSAT-BB list, and will also post that information and other news from the convention on my @WD9EWK Twitter feed. If you don't use Twitter, you can still see what I post there by visiting this link: http://twitter.com/WD9EWK The convention site is in grid DM26lc. AMSAT thanks Frank Kostelac N7ZEV, a long-time AMSAT Area Coordinator in southern Nevada, for leading the AMSAT presence at this event. I am happy to be working with/for him this weekend, and looking forward to spending more than one night in Las Vegas this weekend. :-) (I have only spent one night at a time in Las Vegas on other trips over the past several years) 73!

While I am in Las Vegas for this weekend's ARRL Nevada State Convention, I plan on doing some operating before and after the convention each day. I want to work some passes from the DM25/DM26 grid boundary, on the south end of Las Vegas, as well as from Lake Mead - a National Recreational Area, and a location that is part of the ARRL's National Parks on the Air event for 2016. So far, I have made one definite plan for my non-convention operating this weekend - an SO-50 pass on Saturday (30 April) morning just before 1400 UTC, at the DM25/DM26 grid boundary on the southern end of the Las Vegas metropolitan area. Beyond this pass, I will look to work other passes in the early mornings and evenings in the Las Vegas area. I will also look to work some passes as I approach Las Vegas on Friday morning, and on my drive home Sunday afternoon. One plan is to stop in the Kingman area in northwestern Arizona, near the I-40 freeway, to work from grid DM35. If time permits, I would operate on the DM25/DM35 boundary in Kingman either around midday Friday or sometime Sunday afternoon. For all of my trips to southern Nevada in the past several years, I have always operated at a single location - the DM25/DM26 grid boundary on the south end of the Las Vegas area. This will be one location I will work from during the weekend. I will also try to activate the Lake Mead National Recreation Area, southeast of Las Vegas, as part of the ARRL's National Parks on the Air activity during 2016. If an SO-50 or FO-29 pass line up with my travels, I may even try to work a pass from the "Welcome to Fabulous Las Vegas, Nevada" sign. The sign sits in the median of Las Vegas Boulevard, next to McCarran Airport and what some consider the "official" southern end of the Las Vegas Strip. While traveling, I will use my TH-D72A HT for APRS to transmit my location, using the call sign WD9EWK-9. One way to keep up with my travels will be to visit APRS.FI: http://aprs.fi/WD9EWK-9 I will also post updates here on the AMSAT-BB, as well as my @WD9EWK Twitter feed. If you don't use Twitter, you can still read my posts on Twitter at this link: http://twitter.com/WD9EWK As always, I will upload these QSOs, as well as the QSOs I make during the ARRL Nevada State Convention, to Logbook of the World. If you would like to receive a QSL card, please e-mail me directly with the QSO details. If you are in my log, I would be happy to send you a QSL card. 73!

To receive our Twitter updates, follow @ARISS_status Next planned event(s): TBD ABOUT ARISS Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

Thursday 28th April - starting at approx. 1630 hrs GMT. Using my TS-2000 ( with pre-amp On ) and my "Elk" antenna I heard first of all OUFTI-1 transmissions which were quite strong with a high elevation. Switched band to UHF and also heard data bursts from AAUSAT-4 and that was also quite strong and easy to capture.

Below are a? couple of clips from ARRL news reports in 2002/3. I understand there are several more high-power SAR satellites planning to use 432-438 MHz due for launch in the next few years. 73 Trevor M5AKA ---- ITU 432-438 MHz Synthetic Aperture Radar Satellite P-Band allocation ARRL Bulletin 45? ARLB045 Newington CT? July 11, 2003 The delegates also agreed to allowed a secondary allocation for satellite borne synthetic aperture radars at 70 cm ---- ARRL Letter 2002-10-11 ARRL, IARU CONTINUE PUSH FOR LIMITS TO 70-CM SPACEBORNE RADARS A just-completed draft revision to an International Telecommunication Union (ITU) Recommendation could result in reining in the potential for interference to amateur and other services from synthetic aperture radars (SARs) on 70 cm. Agenda item 1.38 at World Radiocomunication Conference 2003 (WRC-03) will consider a request to allocate up to 6 MHz of spectrum for SARs in the band 420 to 470 MHz to be operated by the Earth Exploration Satellite Service (Active)--EESS-Active. At issue is whether the EESS allocation could be established without interfering with incumbent services, including radiolocation and amateur. "ARRL and IARU (International Amateur Radio Union) will continue to oppose SARs operating in the most active portions of the amateur 70-cm band," said ARRL Technical Specialist Walt Ireland, WB7CSL. The spaceborne SARs would be used to measure soil moisture, tropical biomass and Antarctic ice thickness, and to document geological history and climate change. EESS proponents contend that the best center frequency to penetrate jungle or forest canopies is 435 MHz. "There is some hype starting up at this late date that gives the impression that the sky is falling," Ireland said, referring to recent reports in the Amateur Radio news media that, among other things, incorrectly claim that EESS proponents are seeking "exclusive use" of 430 to 440 MHz and that the EESS issue is a new one. While some occasional interference from SARs to amateur systems would appear inevitable, Ireland said, efforts to minimize the impact of the EESS (Active) operations have been under way for several years. "Although the SAR interference criteria limitations in the revised Recommendation SA.1260 automatically would eliminate three of the SARs, amateurs can still expect to receive interference from some of the remaining SARs on a limited basis if WRC-03 allocates frequency spectrum between 420 and 440 MHz to EESS (Active)," he continued, "especially if the allocation is made primary." The revised draft would keep four of the proposed SARs and eliminate those with peak radiated power levels from 400 W to 10 kW--that is, average power levels above 25 W, he explained. Work on the major rewrite to ITU Recommendation SA.1260, hammered out by ITU-Radio Sector Working Party 7C over the last several years, wrapped up October 4 following a weeklong meeting. The draft recommendation sets interference criteria limitations for SARs to be operated by EESS (Active) in the 70-cm Radiolocation and Amateur and Amateur-Satellite Services band. Ireland represented the ARRL on the US Delegation to ITU-Radio Sector WP 7C. Ken Pulfer, VE3PU, represented the IARU. For the past two years, Pulfer has been chairing the drafting groups that worked on the revision and brought it to its present status--along the way incorporating protection for amateurs. SARs and the Amateur Service can coexist at 430 to 440 MHz "by taking appropriate technical and operational measures," the draft revision states. The Amateur Service is primary at 430 to 440 MHz in Region 1 and secondary in Regions 2 and 3, which includes the US. "It should be remembered, however, that an ITU-R recommendation is just that--a recommendation, not a regulatory instrument," Ireland cautioned. He notes that 18 sharing or compatibility studies--in which the ARRL and the IARU have actively participated--have been conducted during the past seven years--eight of them completed in the past two years. During the Conference Preparatory Meeting next month as well as at WRC-03 next June in Geneva, the ARRL has pledged to maintain its stance against egregious interference from SARs to Amateur Radio. The US also has expressed opposition to SARs that could interfere with its radiolocation systems in the band. Earlier this year, the FCC's WRC-03 Advisory Committee and the National Telecommunications and Information Administration's Radiocommunications Conference Subcommittee recommended no change to the Table of Allocations in the band 420 to 470 MHz as the US position. Both panels determined that SAR transmissions could periodically impact amateur reception and even held "the potential for significant interference." ---- On Friday, 29 April 2016, 15:15, M5AKA via AMSAT-BB wrote: The ITU assigned 432-438 MHz to satellites using Synthetic Aperture Radar some 13+ years.

I plan on being in Nevada from May 8th through the 15th. Among the places I'd like to operate from are DM16, DM07/08/17/18, DM27, DN00/10 and DN01/11. Also possibly DM28 or DM19. Another op told me that he plans to operate from DM19 on May 7th & 8th. Will check with him afterwards and see how he did, then decide my exact plans. For those that want more details, please see my special webpage on QRZ: https://www.qrz.com/db/N4UFO/P I have a map, pics showing locations and a detailed explanation of my plans on that page. There is a link to a special 'rover' twitter feed where I will send out information as I can (spotty coverage in Nevada) and you can watch for that information by simply saving the link and checking it regularly; no twitter account is required. I also have a special e-mail account while on the road and there are links to follow my travel progress via APRS, provided my signal is getting out to the network. It was suggested that when I announced my plans, I should clearly state my objectives. My operations on this trip are intended to pass out grids to as many people as possible that need them and some of these are rarely heard grids. To that end, I would like to request that if you need the grid, please call me, but please be brief with your calls, be courteous to other callers and try your best to only work me ONCE per grid. And if you already have a grid confirmed, it would be considerate to leave the precious airtime for others that need it. (If I am working a grid line or corner and you need at least one of the grids, by all means call me!) I would like to further ask that folks do not blind call me, do not call me if I temporarily lose the bird and please do not 'tail end' on others working me. I am running 5 watts or less. If someone starts calling me, you will likely be PREVENTING me from getting into the bird. (And when one person calls, others tend to start calling, compounding the problem.) On FM, your signals may cover mine, preventing me from getting in (even if no signal is being heard - two or more signals can clash and nothing gets through). And on the linear birds, a loud signal (anywhere in the transponder) may turn on the AGC limiter and raise the receive threshold, preventing me from being heard despite being heard just a few moments earlier with the same power settings. (Calling on the 'tail end' of another QSO can cause this as well.) I am not traveling alone and satellites are not the primary purpose of this trip, thus, I have other things to consider; so please be understanding if my plans vary a little bit. I will also try to operate from 'the road' from a few grids squares along the way out & possibly the way back as well. That will mostly be on an ad hoc basis, but if I think I might be able to stop somewhere of interest, I will try to give notice of the possibility, ahead of time. Again, best to watch my twitter feed. More details on all this are at the QRZ page linked above. Good luck to us all, happy hunting and I look forward to working everyone "from the high desert!" - 73, N4UFO P.S. For those that asked, no I will not be going to the Area 51 gates. X^D But I WILL try to operate from the Little A'Le'Inn parking lot.

Things are going well for AMSAT here at the ARRL Nevada State Convention ("NVCON") in Las Vegas. Except for one thing - the weather. It has been raining here all day, sometimes hard. Frank N7ZEV and I have been working at the AMSAT booth, talking about satellites, and showing off different things on my tablets. You can see more about that, including photos, on my @WD9EWK Twitter feed - or visit this link: http://twitter.com/WD9EWK If the weather breaks later this afternoon, we'll look to do some demonstrations outside before the convention closes at 6pm (0100 UTC). The convention continues tomorrow until midday (around 1900 UTC), so there may be some chances to do demonstrations then - assuming it's not raining tomorrow morning. 73!
