Es'hail-2 transverter ready
by Remco 26 Jun '18

26 Jun '18

I built my second Es'hail-2 transverter with easy available building blocks and junk box / flea market components. I consider the future (narrow band) transponder as a 'normal' amateur band (with latency) and therefore will operate 'simplex'. This means the LO frequencies are switched by the PTT (TX-enable). Picture: https://pbs.twimg.com/media/DgZGilPWsAAWSQh.jpg:large Some technical details: RX / TX LO: ADF4351, programmed by an ATTiny13a TX mixer: HMC213 RX mixer: home brew with ADE-1 + J310 HPA: surplus ex-UMTS module (P-1 dB @2400 MHz = 10W) IF RX / TX: 432 MHz (or something else) Dish feed: 6t 2.4 GHz LHCP helix and 10 GHz LNB 'peek a booing' through the helix 73, Remco PA3FYM

Reply to WD9EWK question ref. FalconSat-3 on Field Day
by Scott 25 Jun '18

25 Jun '18

-----/ EDIT / ----- Unfortunately, FalconSat-3's passes didn't line up with my time in northern Arizona. I wonder if anyone made QSOs through that digipeater. Patrick WD9EWK/VA7EWK -----/ EDIT / ----- Patrick's question above is from another thread that got long, so I thought I'd reply as a new message since this is a specific topic. I don't know if there were any true 2-way APRS exchanges on FS-3 during Field Day, but I did download an FD-related BBS message from KB6LTY and on the following pass, my reply to her was uploaded to the satellite. That's not a QSO, but just wanted to mention it since not everyone sees the postings on FS-3's BBS. Can't post an image with this message, but here's a link if anyone would like to see what a BBS message on FS-3 looks like: http://www.qsl.net/k/k4kdr//images/kb6lty-msg.png As for regular APRS packets, I wasn't awake when W4LHS (COASTAL AMATEUR RADIO SOCIETY, Savannah, GA) was active via FS-3's packet digipeater, but my K4KDR-15 iGate heard them being digipeated. So, their APRS traffic was relayed to aprs.fi. Here is a link to a screen shot of those packets: http://www.qsl.net/k/k4kdr//images/w4lhs-1--igate.png So, it was nice to see at least some Field Day traffic relayed through FalconSat-3. 73! -Scott, K4KDR

AO-92 FM on FD... what a mess, wish it was in L-band today.. , perhapswould be better to score points just for listening ONLY and getting call sign's + exchange from the bird to get more operators HEARING the bird and less trying to transmit without being able to hear it...say 1 point for each callsign and exchange monitored...and 2 for each qso after the first one.... something to get guys listening more and less trying to key them up ( perhaps for first time... ) just a thought...ko6kLaudio recording. http://www.valleymedia.org/satchat/2018-06-24-1800z--AO92-FM-Uv--CQFD-mess-… http://www.valleymedia.org/satchat/2018-06-23-2033z-sat-Ao-91-cq-fd-mess-ha…

Field Day (whew)

For Dave KG5CCI, I read through the whole thing you wrote and I cannot fault you at all. You did the right thing all the way through. I guess it all depends on the situation. Maybe by next year I hope to be better skilled on linear sats. Thanks and 73, Dave AD7DB

James, I don't take exception with anything you have said. I would rather operate linear SATs anyhow. What bothered me about FD and generally any day, very few if any of them are worked using CW. CW is easier to copy and I think SAT exchanges during FD or otherwise would be faster and more efficient. If I could wish for one thing, that would be it, everyone try making CW contacts via SAT!

Field Day Kudos
by Stephan Greene 25 Jun '18

I handled satellite ops for K4LRG (Loudoun Amateur Radio Group, LARG). Nice hilltop location at Franklin Park in Purcelville VA,excellent coverage to the south and east, decent to the west, and some trees to the north. 1st QSO was VE3YRA on 1st Ukube-1 pass, last a Brazil station on AO-7 just before 1800 UTC. About 135 QSOs before I remove AMSAT dupes. This is about double what we did last year; very happy about it. I'd like to give kudos to folks who stood out in my mind over the weekend: - The ops at W5RRR (JSC club). QSOs on 7 birds, CAS-4A @ 1539 6/24 UTC was VERY SPECIAL. A young man who is very interested in ham radio at the mike. You were his 1st satellite QSO, and he was double excited when I told him where you were. You made this kid's day! Thank you sirs. - K4BFT and VE3YRA - you guys were everywhere with solid signals. We worked BFT on 11 satellites (missed AO-7) and YRA on 10 (missed AO-7, AO-73). We worked several other stations with great signals on multiple satellite, these 2 stood out in my mind. - N8HM. Paul, how you do it with 2 817s (fully manual) and hand-held antenna continues to amaze. Thanks for the QSOs. - The ops on an early Sunday FM satellite pass (I forget which one). You were remarkably disciplined, even by FD standards. - The many ops who stayed with us to complete a QSO despite QRM, low elevation angles, jumpy AO-73 transponder, or insufficient caffeine in me on Sunday morning. My apologies to anyone I stepped on or became "that op." - Customer support at Yaesu in California. Murphy struck on Thursday; I broke a cross boom U-bolt on my rotator while getting ready. I called Yaesu; their customer service rep checked with their technician and they shipped a replacement to me. Which arrived Saturday! (I was worried it would not arrive in time and found a substitute locally that worked OK for FD). Excellent customer service. The number of satellites this year made for interesting times when one pass started while another was underway. We had QSOs on every CW/SSB or FM-capable satellite except AO-7 Mode A and AO-92. Weather was very wet (rained all day Friday and showers on Saturday) and a severe t-storm 1 hr after shutdown on Sunday (2 shelters damaged but no injuries thankfully!). All the satellite QSOs and Sunday gorgeous sunrise and morning made up for it. I still need to get digital modes working (can copy NO-84 and FS-3 but don't have uplink working) and build an L-band antenna for AO-92. And not wait until early June 2019 to get started! 73 de KS1G (K4LRG op)

Field Day

Well, this certainly was more fun than last year. I participated as W5SI with the Texas Emergency Amateur Communicators (TEAC) club in Kingwood, TX again this year. We doubled our satellite contacts from last year. Our station had an unobstructed view north and south. To the east, we were next to a building so zero visibility. To the west we were blocked the first 20 degrees or so. Had to wait for the highest passes. We started off field day working SO-50 and AO-91 on the first passes. Everything was done manually, radio tuning and LEO pack antenna turning. That makes it a little more fun as more people can be involved. Did not work a single station. By 4:00 PM I decided to head to the house. We had to have high elevation passes due to our location. When I returned an RV had moved along side the antennas. The antennas were moved another 20 feet away and had to place the radio in the back of my car as the coax was not long enough to reach where the radio was before. Next pass that was high for us was FO-29 in early evening around 8:30 PM. I have not worked an SSB satellite since 2001. Have been using the HT and mobile radio with the Arrow. But, heck it is like riding a bicycle. Found my downlink, cruised around and found W5RRR, my friend Andy, W5ACM, at the mic. We made a contact with them. Next good pass for us was SO-50 later in the evening around 10:30 PM. Unplugged the power and coax cables, closed up the car and went inside for some air conditioning. Time to work SO-50. A good 14 minute pass, we should make one contact, easy as pie. Hooked up the radio and started listening, nothing. Did not hear a peep (you can see where this is going?). Pass was about 90 degrees and still nothing. Someone looked down and said, the coax is not plugged in. Uh, huh, in my haste, forgot to plug them in. Quick which is 2m, which is 70cm. Hooked up and listening. Heard a familiar voice. Yes, last couple minutes of the pass, worked W5RRR with Andy once again at the mic. What are the chances? Out of all the stations on the air during field day, we wind up working not only someone else in the Houston area but the same station. Murphy tried to ruin our field day, but we got over on him. Those that were there to help and watch the satellite contacts enjoyed it and as I said, we did double our score from last year. We had 2 this year. Maybe next year will use Satpc32 for radio control and double this year's score. Be sure to get your scores into me. They are due by 11:59PM Central Time on July 9, 2018. A lot less time to submit than ARRL. We do this so that we can get our story out in the next issue of the AMSAT Journal. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards AMSAT Board Member 2016-2018 ARRL Awards Field Checker (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat
