Re: Some New kind of interference that is showing up at my location

I interpret the signal to be approximately 2 kHz bursts spaced every 5 kHz.
See the attached Power Line RFI complaint from a few years ago.

 Recently I have decoded a few instances of FT8 signals on 50 MHz that has been described as
" Reflections from high speed aircraft creating a second Doppler shifted signal"

Since my QTH is not far from NAS Oceania and many aircraft,
 I guess this double decoding will become common as the number of FT8 signals cross the flight paths!

Dear Members,


Lately I have been detecting a new kind of interference to my station.   It doesn’t seem to affect many of the grabbers (I expect that is because they are only 200Hz wide) but I run across it on the Amateur Bands when trying to work FT8.  It seems to be around on 20M as well as 6M.   Some here have said it looks like a plasma TV hash.   Since I have never experienced that before I have no clue.   I took a picture of the waterfall spectrum display on my ICOM 7600 so you can see what I am seeing.   Has anyone a clue to what this is?



Any suggestions welcome


Take care and have fun.
