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:

Channels 1-20 are left-to-right then bottom.

Does the embedded audio work for anyone? I think it’s not even an official Lemmy/Markdown feature.

It works in the default Lemmy web UI. I tried it with Opera (Android) and Firefox (Manjaro). It relies on the browser's media player.

There's still the link below it, for when it doesn't work, which I expect from most Lemmy clients and probably Kbin too.

Oh, I didn't check if the compatibility link is any different, I assumed it was the same.

Of course you cannot embed an external site in a comment but the raw file does seem to work, in browsers at least.
