One way to find out where it comes from is by using a horn antenna because it is very directional. If you place the horn antenna on a turn table and connected it to a receiver. You should be able to find out which direction does the noise come from by turning the table. If the noise is

Scot, We had a problem at our lab that sounds very similar to yours. It turned out to be dirty power line insulators. We were in the midst of a drought at the time and the rains were not doing a good job cleaning the insulators. The dirt built up to the point that there was conduction through

Hi Scott, You wrote: This is broadband, from 30 MHz to 1 GHz, at levels up to 70 or 80 dBuv. It is not like a flat carrier but rather more like PWM driven motor noise. It lasts from 15 seconds to 1 minute in duration. Then ambient returns to normal. I've had a very similar problem, 20-30dB
