Wow ... and how timely.
I believe I have a spectral 'display' of one of those; it has been
bugging me for awhile in my part of the world.
Maybe post it a little later ...
The key part was this:
"The baseband black and white video signal
is shifted up to approximately 20.5 MHz
to 22.0 MHz."
That's right in the area of this RFI I have seen, with some
weaker signal artifacts detectable up through 26, 27, and
even 28 MHz..
