Just before the UmKA-1 crossed over Brazil in this morning, I decided to monitor the Colibri-S RS67S (Random decision 
). The satellite was very high in the sky and when I started the SDR I was very surprised. The satellite was transmitting an image in digital protocol !!
Unfortunately, I didn’t turn on the SDR in time to collect the starter data and I lost the image. I was sure that the GEOSCAN event was happening only over Russian territory 
I’m missing image number 2, 5 and 7 from RS52S, RS59S and RS67S.
Is anyone willing to have a look at this wav file and tell me if is a matter of signal quality or if my decoders are all non functioning?
I know it is not perfect at the end but i feel it should atleast start decoding something out of this.
Edit:The satellite is Stratosat TK-1
Jomjom79
It decoded to a 21,5 kb KISS file.
I’ve already got number 12 from RS52S with 21,4 kb.
I didn’t examine every single frame to determine the cause, but I also received several ‘black’ images despite a complete decoding.
Just hang on and try to combine several receptions.
Got my QSL card for RS67S.
