[amsat-bb] What happened to the ISS SSTV audio level?

[Hans BX2ABT]

Same here. Good, strong signals on a low pass, but QSSTV couldn't sync. 
Got a partial image from enhancing the recorded audio.

In the same pass they transmitted another image, but couldn't even hear 
and see any SSTV, only a strong carrier.
