Observation 11959506: ISS (25544)

Regarding Observation 11959506
Hi! I see you scheduled ISS SSTV observations on my GS. Unfortunately, having a strong signal and clean audio I can’t decode images, even with external apps. Seemingly, the same quality audio are fed into MMSSTV produces images decoded by SatNOGS client itself, but captured by others.
I see, you have more or less the same problem with SSTV
