Subject: [RFI] Power Line Noise

This past fall I've been plagued with noise wiping out the lower end of 20m
(I'm a CW op so this is a big problem). I fades off above 14.200, but I can
still hear it.



I can hear it on most bands but it is strongest on 20m. It is also in the MW
band 6.5mhz seems to be a peak but its very broad banded.



Switching to AM it really sounds like power line noise.



Link to videos. I'm switching in / out the noise blanker a couple times in
the video.
