I was so excited about SSTV that I didn’t even look at the UmKA-1 telemetry packets
Happy New Year, friends! / S Novym godom, druz’ya!

I’ve checked my recordings, and indeed!
I received it three times today, but not yesterday yet.
Completion of SSTV broadcast from UMKA-1 on January 2, 2025 at 18:42 UTC
Text congratulations broadcast will continue.
I observed RS27S and RS58S yesterday at 13:0x and today at 01:2x UTC for New Year’s holiday transmission in SSTV, but unfortunately heard nothing, no SSTV, no beacons.
However, Observations from SONIKS show SSTV and beacon transmissions.
Do they only transmit over Russian territory?
Daniel, I received both satellites here in Brazil
My first reception of SSTV transmissions were:
MONITOR-3 (RS58S) = 2025-01-04 12:31UTC
UTMN-2 (RS27S) = 2025-01-04 11:09UTC
HyperView-1G (RS66S) is also transmitting SSTV. I have seen some reports of reception in addition to THIS post on the R4UAB website
Tried for both yesterday (04-Jan) on 090x (Monitor-3) and 091x (UTMN-2) passes over UK. Audible heard broadcast from both but very noisy and breaking up. Got a partial decode from UTMN-2 but v. low quality - you get just about make out there is some image there but I’ve no idea what it is really. Monitor-3 triggered a decode on MMSSTV but lost the signal again almost immediately. Possibly better / higher passes tomorrow morning so might try again then.
Found the error.
I cloned a module
in Gpredict and put all the currently SSTV transmitting satellites in.
I now noticed that the chosen ground station
was not mine. I don’t know how this could change by itself.
I already thought that the passing times are a bit odd.

Hi!
On February 1-2, it is planned to broadcast images using the SSTV protocol from the UMKA-1 RS40S. The broadcast was organized as a sign of respect for the developers and enthusiasts of the MAYAK satellite, which descended from orbit in 16 January 2025.
Transmission starts on February 1, at 07:00 UTC
The transfer ends on February 2 at 18:00 UTC.
SSTV - Robot 36 format
The interval is 120 seconds.
Frequency - 437.625 MHz
Transmission can be interrupted if necessary without prior notice! (temperature rise, battery discharge, etc.)
There is also a text message with congratulations in honor of the celebration of the Chinese New Year. The text broadcast will last until February 9th.
@ra3ppy what baud rate is being used currently, 2400, 4800, or 9600?
9600 bps

No text messages seen.
This week I have fitted a new antenna inside my roof (prefer it to be outside) its a Dimond X-50 and this it what I have received on the last pass at 22.5 Elev.
I’m only using rg58 cable at the moment but I will replace this with a better quality cable with less losses
Hi. The speed of the 9600 almost always remains the same, except in cases of certain events or requests from amateur radio operators to conduct experiments. In this case, the speed can be set to 2400 and 4800 bps. Sometimes UMKA works at 19200 bps (we additionally notified IARU), but these are short-term inclusions.
Hi. I’ll restart it in the evening.
Many thanks for the update
