Hi Daron!

After editing the WAV file from my TH-D74, I was able to
get some of the picture that was sent starting around
20:42:49 UTC this afternoon. That image can be seen at:


I took the WAV file into the Audacity sound-editing program,
and used the Amplify effect a few times to get the SSTV
transmission to the point QSSTV could decode most of it.
I have posted this picture, the original WAV file, and a
few other edited WAV files in my Dropbox space at:


(look in folder "201904-ISS_SSTV")
