The main image in post was decoded with WXtoIMG as both noaa-apt and SatDump fail to synchronize it correctly.

Unprocessed image from noaa-apt:

Waterfall:

There you can see some breaks, the noticeable horizontal lines.

Which sounds like so (note: the waterfall shown above isn't from the same time as audio):

And the bonus, DSB images:

Nope. I also had those lines when I tried before, so I thought it's something with the satellite. Maybe there is some interference. NOAA-19 uses different frequency for DSB. I'll have to try with NOAA-18 (and hope it doesn't cut off again), that should be on same frequency as NOAA-15. But I didn't notice any interference.

Thanks for that setting. That looks nice.
