On 27 July 2026 members of the Oslo Group of NRRL, callsign LA4O. used an 80 watt 23cm transmitter to send a voice command to satellite OPS-SAT PRETTY to instruct it to play Doom. Story now being reported on several sites including mezha.net/eng/news/mezha-c3a… #amsat #hamradio #hamr

As they used to say on Monty Python, "And now for something completely different..." ARISS SSTV Series 35 has a surprise in store. Check the graphic for the spoiler alert!

JO-97 13z FT4 JJ3DKQ 局とQSO ♪ (*^^*) TNX この衛星でのFT4は,なかなか難しかったはずなのだが… 衛星追跡・制御ソフト「OscarWatch 」と「IC-9700」の組み合わせは優秀で 最近は「SatPC32」の出番が無くなりました…(*^^*) #OscarWatch

OscarWatch is the software AMSAT-SM recommend for tracking and ham radio satellite communications for all platforms. Get it at oscarwatch.org/ #amsat
OscarWatch FT4 Waterfall now has flattening so big signals do not make the weaker ones disappear.

FO-29's operational schedule (UTC) Starting November 17, the period of full sunlight will end for approximately one month, so operations will be conducted on a scheduled basis. Additionally, full sunlight is expected to return from around December 19 through early August 2027, so continuous operation should be possible during that time. Please be advised that starting November 17, we plan to send a command to turn the transmitter ON at the following times; however, if the transmitter does not turn ON within two minutes of the command being sent, we will terminate the command procedure.

Soon starts.. remember in OscarWatch SSTV you in record passes automatically to decode again, even more helpful if you get a poor decode I can fix it in the code!
It's about 48 hours until the start of ARISS SSTV Series 35, "Space Memories." A series of 12 images will sent from the ISS on 435.550 MHz. Good luck!

Today I recommissioned my 3D satellite rotator system (AZ-EL-FLIP) based around an Alaskan Arrow antenna. It’s not fully auto but will allow me to keep warm in the RV. I also configured my /P FT847 for #OscarWatch inc a couple FT4 Qs on RS44 with V2000 vertical. @mm9sql @AmsatUK

Looks like tomorrow's OscarWatch release will be just in time for the next round of ISS SSTV transmissions
We're answering those requests for a longer SSTV event with a YES! ARISS SSTV Series 35 is scheduled to begin next Monday and run till Nov. 16. The event will overlap with NASA on the Air weekend, so this series will feature a "Space Memories" theme. Check out the graphic for event details.
