[RFI] Noise centered around 20 meters

[Gary]

Thanks Rolan,

	No solar panels around here and the noise is still there at 3:00 AM. We were able to track the noise to an area the size of a block or so with a portable shortwave receiver based on signal strength. It is either one of a couple houses, or some type of utility equipment in between them.  I am constructing a loop tonight to use with the portable shortwave receiver tomorrow in hopes of narrowing it down even more.

Thanks and 73,
Gary "Joe" kk0sd

Gary and all,

Curious, have you tried google earth to look at the location where the noise may be coming from.  If solar panels are there they may have been there when the google earch picture was taken.

Do you  think it gets less at he end of the  band you are listening due the the selectivity on ur rx/antenna?
Does it show up on other bands.
The repition 'pulsing' rate sounds close to 60 hz.

I had my computer play a 60zh square wave and it sounds the same rep rate to me.

Some more ideaa

I have some 'noise' that starts around 11 MHz and gets stronger as I tune up the band. It is about S8-S9 across all of 20 meters and finally plays out around 15.600 MHz. I made a video showing the issue and placed it on Youtube here:
