Hi Bruce,
I assume your noise is on top band (just a wild guess). I will lay on
plans this weekend to drive a ways south with the R-599 on 160 meters
AND an AM broadcast band receiver that allows some directive sniffing to
see if the windmill farm down that way is um... 'polluting'. I haven't
looked that far ahead on the weather forecasts. If it's icy or there is
a blizzard this old goat ain't going there. In the process I suppose
I'll find out if my car is 'clean'. I've been lucky so far.

Getting noise from my NW direction. Does not seem to be local. Started
wondering what, at distance, could be causing it. At times it seems to have a
rhythm like a motor.
There are a lot of power generating wind mills showing up. Checking through
Google, they generate DC and convert to 3 phase AC it with an inverter. The
frequency and phase of the inverter is controlled with a sample from the power
grid.
Could their inverters have enough sine wave distortion to have harmonic energy?
So my question is: Does anyone have first hand knowledge of interference on the
low bands from power generator wind mills?
