Recorder Catch on 6925.07 USB

Caught 2 SSTV streams on the audio recording.  The first one at 0250 will not demodulate.

The 2nd one was caught by MMSSTV at 0349z as Robot 24:

Much better copy than mine JF - the first two were also Robot 24, but couldn't get any image quality from the decode.

03:49z Robot 24 SSTV:

First one at 0250 was in Robot 24C mode:

The second transmission at 0349 was much weaker here.

It's obviously Fansome transmitting from Mars.

I added pass band tuning to my sdr playback app, which allowed me to tighten the bandwidth around the SSTV signal, I think it improves decoding a little, compared to the previous image I posted?
