I want to try to receive it.
But I found that I couldn’t use the StratoSat TK-1 Decoder software normally.
I can open the GUI and stratosat.exe, but the soundmodem doesn’t show up properly (I can see it in the task manager, however) and stratosat.exe keeps trying to connect.
What’s the problem?

Try to start the Soundmodem before starting the decoder GUI.
As an alternative to the Soundmodem use gr_satellites.

Hello! You need to try changing the settings in hs_soundmodem.ini and try again! Replace

Why are there only picture transmissions over central/eastern Europe? People from Portugal and Spain want images too! :sweat_smile:

Image 7, captured 2024-02-29 07:53 UTC

Interestingly the signal level was high, but the end of the image is missing. I migh be able to get the whole image from the 3 transmissions if I combine the kss files somehow.
