Given where that is at in the band i wouldn't be the least bit surprised if that isn't either spillover of shenanigans on 7200 or someone trying to jam them.

How is this done?
-
With a program like Easypal. It generates audio that results in an image when viewed on the waterfall. Flex radios have it as a built in feature, and I’m sure this is a Flex or some other SDR because of how wide it is.

Interesting. Thanks for the reply!

That's the best quality waterfall image I've seen.
On another forum there was a guy who posted a pic of a waterfall image sent by Ukrainians (? -- that's a guess) in the Ukrainian-Ruassian radio war. It was a series of Cyrillic characters.

A few of the 41 meter pirates are doing this.

I see super wide blasts on 20m. Maybe they're waterfall pirates. I'll mess with my waterfall speed and see if I pick anything up.
