Two way SSTV exchanges using PSAT2
by Robert Bruninga 14 May '20

14 May '20

The PSAT2 team has decided to enable the 10 meter uplink for user SSTV experimentation with two-way user SSTV communication. PSK31 usage has been light and SSTV downlink seems almost perfect as reflected in PY5LF's example posted before, so why not let people do 2-way SSTV? Simply transmit SSTV using SSB on the 29.4815 uplink WHILE someone else is transmitting PSK31. Ah, there's the rub. The transponder has to see a PSK31 modulation somewhere in the passband (not used by SSTV) in order to key up the transponder. AND the uplink station has to do the Doppler correction. But unlike PSK31, SSTV is not phase coherent and so RIG control using any satellite software can do fine. Also, if you can run two instances of SSTV, you could see your own downlink on 435.350 for Quality control! Maybe we can enlist the authors of SSTV software to not only generate the SSTV tones, but also a mild PSK31 tone carrier down below 400 Hz. Anyone? Actually, the "psk31" tone only needs to have 31.25 Hz AM modulation on the tone carrier to do the trick, doesn’t really have to be PSK31.. Bob, WB4APR

https://network.satnogs.org/observations/2201621/ It appears to have changed modes at about 9:40z this morning.... I don't think you were dreaming.

MFJ-916BMN duplexer
by BeetleJerald Oliver 14 May '20

14 May '20

I am still having problems with the 9700 on Mode J. Has anyone yet used the MFJ-916BMN duplexer on their system? I like the fact that it is designed for outdoor use and can be mounted to the mast. I have a comet CF-416, but would have to build a waterproof box for it if used and left on the tower....Any thoughts 73 Jerry KJ4EU

AMSAT NEWS SERVICE SPECIAL BULLETIN ANS-135 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: * HuskySat-1 Designated HuskySat-OSCAR 107 (HO-107) SB SAT @ AMSAT $ANS-135 ANS-135 AMSAT News Service Special Bulletin AMSAT News Service Bulletin 135.01 From AMSAT HQ KENSINGTON, MD. DATE May 14, 2020 To All RADIO AMATEURS BID: $ANS-135.01 HuskySat-1 Designated HuskySat-OSCAR 107 (HO-107) On November 2, 2019, the HuskySat-1 cubesat launched on the Cygnus NG- 12 mission from Wallops Island, Virginia, USA. The satellite was con- structed by the Husky Satellite Lab at the University of Washington, and utilizes an AMSAT-constructed radio system for primary communica- tions. Deployed from the Cygnus vehicle on January 31, 2020 after de- parting the ISS, HuskySat-1 began a 3-month educational mission. Upon completion of that mission, the satellite began operation of a V/u linear transponder in amateur service. At the request of the Husky Satellite Lab and AMSAT teams, AMSAT here- by designates HuskySat-1 as HuskySat-OSCAR 107 (HO-107). We congratu- late the Husky Satellite Lab, thank them for their contribution to the amateur satellite community, and wish them continued success on this and future projects. 73, Drew Glasbrenner, KO4MA AMSAT VP Operations / OSCAR Number Administrator [ANS thanks Drew Glasbrenner, KO4MA, AMSAT Vice President - Operations for the above information] /EX In addition to regular membership, AMSAT offers membership in the President's Club. Members of the President's Club, as sustaining donors to AMSAT Project Funds, will be eligible to receive addi- tional benefits.

It hasent been put into LOTW yet. It only just officially got its OSCAR number which makes its legally a Amatuer Radio Satellite. I am sure it will be added very soon. 73 Nick KE8AKW
