Today it was announced that an event will occur in parallel with the SSTV image transmission by the UmKA-1 satellite.
It will APPARENTLY be a global event, and the satellites are as follows:
Start: 09/08/2025 at ~00:00 UTC
End: 11/08/2025 at ~00:00 UTC
Please note that the images will be transmitted in digital protocol.
See the original message sent HERE
“No, only in the radio visibility zone of Russia, China, and Central and Eastern Europe”
Unfortunately !!!
are these transmitted in GFSK9k6 - AX.25?
“Vizard-ion (RS68S), for technical reasons, will not be able to continue transmitting. The rest - according to the schedule, transmit images”
It’s a GFSK9k6 - AX.25 (Geoscan framing). We have a SoundModem available for this…Download HERE
Check the virtual audio cable settings, input device in sound modem, audio settings and sample rate.
@EU1SAT thanks for your help btw
Right I’ve played around with the band width and had to select wide FM and adjust it to 16.6Hz for it to detect the telemetry which works fine and a partial image.
My other issue is poor signal and only being able to read some of the data.
Here’s what I’ve got so far.
Turn off second channel on SoundModem.
Have you got rid of a gap?
I’ve tried many combinations with it of/off different band width and so on but no full picture I think its down to a poor quality signal being received.
This is all I have been able to decode
The image with blue background consists of 762 packets.
It only needs a few packets to let the image look pretty distorted.
