That signal is actually pretty cool…
Sometimes there was a preamble before it started, and then it would jump around frequencies a little.
They weren’t evenly spaced, the lowest I was around 6.9753 Mhz to the highest 6.9576Mhz (USB).
Around 10s between bursts too.
Don’t really know what is going on, but this is what I saved:
Update 2021-06-27: The signal is likely from US Navy, not JORN.
