Hi.

It's pretty horrible here, much worse than you would expect for a 
residential neighborhood--almost at a level that you would expect in a 
commercial district.

It isn't conventional power line noise either--this stuff sounds like it is 
being generated by some type of digital equipment and it is worst between 
700 kHz, and 20 MHz.  It seems to roll off above 20 MHz.
