ChrisSmolinski:
Keeping the show as a WAV file would eliminate the timing problem, but the resulting audio files would be huge. You could keep the SSTV as a separate audio file in WAV format, and send the program audio as an mp3 or WMA or whatever, but that might be a hassle for your relay operator?
Also, for whatever reason, I have noticed that SSTV images, when transmitted in AM mode, often looked "washed out". I'm not sure if this is due to the transmitting or receiving side (or both). IIRC I've sometimes demodulated them in SSB mode, resulting in a slightly better image.
Echo_One:
It could be a hassle, but it is something to think about... I will discuss with my relay operator as you suggest.
Anyway, where you heard me from, did I bury the Peskies?
How did the first image come out? The Pikachu one
ChrisSmolinski:
Yes, the signal from the first transmission was strong. The later show, around 0200z, was quite weak.
The first SSTV image was split between two SDR recording files, so I didn't decode it.
PRBRELAYS:
It's all my fault, I took the file and saved it as an mp3 file! :(

It would be interesting to run the original WMA file through an SSTV decoder, and see if the slant issue is there as well.
