Just fowarding this. 73 Bob W7LRD -------- Original Message ---------- From: Greg Stahlman <kj6ko(a)innercite.com> To: Wswss(a)mailman.qth.net, pnwvhfs(a)googlegroups.com Date: February 6, 2019 at 5:12 PM Subject: [PNWVHFS] FT-736 with 220 and 1.2 Before this goes on ebay, I have the following… FT-736R with MD-1 Desk Mic, 1.2 and 220 modules, Keyer, CTCSS Tone board. Internal supply still works and comes with AC power cord. Only thing missing is the little door that covers the A/V jacks for the 1.2 module. Excellent cosmetic shape and everything works perfectly! Recent "basic" tune up. (Power, ALC, RX and Freq check) No manuals. No original box. $1100 + $75 shipping and insurance. (It will be boxed very well and sent Fedex) Paypal preferred. Local pickup if you want in Sacramento area. Email me direct if you want photos. I'm pretty sure there aren't any on here, but message to scammers/parts swappers…..Every board, module and option plus serial numbers have been logged, photographed and has hidden marks with IR ink so don't even think about it! 73 Greg Stahlman KJ6KO Trustee Northern California 900 Repeater System NC9RS kj6ko.com nc9rs.com -- ~The Voice of the Pacific NorthWest VHF Society~ You are subscribed to the Google Groups "PNWVHFS" group.

One reason for some drifting, even with computer control. is not using up-to-date keps. Another is inaccurate time on one or both computers. But always be patient to those standing outside in rain or snow, and be patient with them. And always have fun. Ron W5RKN

Umesh, A question and comment on your statement: > (b) Sometimes I hear a station calling CQ and it remains on the same > frequency during successive CQs, The method SatPC32 and HRD and others employ is keeping the “frequency at the satellite” a constant, varying your uplink and downlink frequencies as appropriate. In your statement above, do you mean by “on the same frequency” that you need not change your SatPC32 controlled frequency to remain tuned in to the CQing station? If so, then both of you are tuning to keep the “frequency at the satellite” a constant. This method is the preferred method of tuning for base stations. Mobile stations may not be able to do it. By keeping “frequency at the satellite” a constant, QSO’s with many participants can converse as easily as though they were on 20m. Ron W5RKN Umesh, If you can tune around and always hear your own downlink on the correct frequency, then you are doing everything right. 73, Paul, N8HM On Wed, Feb 6, 2019 at 12:42 PM k6vug at sbcglobal.net <k6vug at sbcglobal.net> wrote: > Good Morning All, > I'd like to understand something that seems to be happening with SSB > birds. > > I realize that they are two kinds of operators - one that has a computer > controlled station and one that tunes manually, and I respect both types. > The following observation is about two computer controlled stations working > via a SSB satellite - > > (a) My station is computer controlled (SatPC32 or HRD) and can hear myself > on the downlink throughout the pass.

Operating SSB sats
by k6vug＠sbcglobal.net 06 Feb '19

Good Morning All, I'd like to understand something that seems to be happening with SSB birds. I realize that they are two kinds of operators - one that has a computer controlled station and one that tunes manually, and I respect both types. The following observation is about two computer controlled stations working via a SSB satellite - (a) My station is computer controlled (SatPC32 or HRD) and can hear myself on the downlink throughout the pass. I can also go up or down the pass band and still hear myself without needing to retune the uplink. It is pretty rock solid, almost like HF operation. (b) Sometimes I hear a station calling CQ and it remains on the same frequency during successive CQs, so I'm guessing their station is also computer controlled. I can tune in and stay on their calling frequency. (c) However, when I can respond, it seems they have to tune their downlink a bit to hear me well. So when they come back to my response, they are a bit off-frequency (about 300Hz) and sound like Mickey Mouse, until I retune the downlink to hear them well again. This keeps happening throughout the QSO. (d) This "drifting" happens only with some stations calling CQ and not everyone. Considering both stations are computer controlled at each end, I'm trying to understand if I'm doing anything wrong/incorrect. Learning to operate SSB sats has been humbling as well as exciting, I'd appreciate any pointers for this situation. Thanks in advance. 73! Umesh k6vug

AMSAT NEWS SERVICE Special Bulletin - ARISS/NOTA Slow Scan TV Event February 8 - 10 ANS-037 The AMSAT News Service bulletins are a free, weekly news and infor- mation service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor at amsat.org. You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: http://www.amsat.org/mailman/listinfo/ans In this edition: * REMINDER - ARISS/NOTA Slow Scan TV Event February 8 - 10 SB SAT @ AMSAT $ANS-037.01 ANS-037 AMSAT News Service Special Bulletin AMSAT News Service Special Bulletin 037.01 From AMSAT HQ KENSINGTON, MD. DATE February 6, 2019 To All RADIO AMATEURS BID: $ANS-037.01 REMINDER - ARISS/NOTA Slow Scan TV Event February 8 - 10 ARISS is running another of their popular Slow Scan Television (SSTV) experiment events. Transmissions began Friday, Feb. 8 at 14:00 UTC and are planned to run through Sunday, February 10 at 18:30 UTC. SSTV operations is a process by which images are sent from the Inter- national Space Station (ISS) via ham radio and received by ham opera- tors, shortwave listeners and other radio enthusiasts on Earth, simi- lar to pictures shared on cell phones using twitter or instagram. SSTV images are being transmitted from the ISS at the frequency of 145.800 MHz using the PD120 SSTV mode. These can be received using ham radio equipment as simple as a 2 meter handheld radio or a common shortwave or scanner receiver the covers the 2 meter ham band. After connecting the audio output of the radio receiver to the audio input of a computer running free software such as MMSSTV, the SSTV images can be displayed. Transmissions consist of eight NASA On The Air (NOTA) images and an additional, four ARISS commemorative images will also be included. See: https://nasaontheair.wordpress.com/ Once received, Images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php You can receive a special SSTV ARISS Award for posting your image. See details at https://ariss.pzk.org.pl/sstv/ Please note that the event is dependent on other activities, sched- ules and crew responsibilities on the ISS and are subject to change at any time. Please check for news and the most current information on the AMSAT.org and ARISS.org websites, the AMSAT-BB(a)amsat.org, the ARISS facebook at Amateur Radio On The International Space Station (ARISS) and ARISS twitter @ARISS_status. +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ AMSAT and ARISS are currently supporting a FundRazr campaign to raise $150,000 for critical radio infrastructure upgrades on ISS. The upgrades are necessary to enable students to continue to talk to astronauts in space via Amateur Radio. We have reached a great milestone with $16,895 raised or about 11% towards our goal.
