What's This Noise On 20M?
 

Hi gang -

I recently returned to 20M CW and am hearing a noise
reminiscent of the old "Russian Woodpecker", only
with a faster repetition rate. It seems to move
around the low end of the CW band and isn't locally
generated because I can hear propagation effects on
it.

Or are these old ears hearing things?

Lots of digital signals on the bands these days -- To hear the various modes
and sounds go to URL:

Thanks; what I'm hearing is on the "Ionosondes, chirpsounders & OTHR
systems page...SUPER DARN OTHR SYSTEM. I didn't realize anyone was
running OTHR (Over The Horizon Radar) any longer since the "Woodpecker"
went QRT.

Yep I remember the OTHR woodpecker -- Kenwood even designed a noise blanker
for it (I think)

Haven't heard any thing like it since (Thank Goodness)

That will seem completely innocuous if BPL is approved..

That radar runs S9 + 40 here when the MUF is right at 20M.
Just about what I expect from BPL.
