Bill: If you take a portable AM broadcast radio, and tune it off of any station, can you hear the noise?
If so, can you use the portable AM radio, which usually have a directional "loopstick" antenna to find the noise, by determining the direction with the antenna null, and walking towards it as it get louder. Or similarly, can you hear it on an automobile AM broadcast receiver that is tuned off of any station? Similarly, drive around and note where it gets loudest. --- Graham == On Mon, Feb 25, 2013 at 7:25 PM, William H.
