Topband: Ionosphere and eclipse. Monotoring tools.

[Katz Ajamas]

I forgot to edit subject and trim so here it is again.

There are a number of research and commercial ionospheric sounders running
pretty much all the time.
If you have a panadapter you can see and if listening hear them.
Lots of info found using the search term: Chirp Sounding OR Sounder
I found this one interesting.

I suspect there are also spread spectrum sounders running.
