Re: Hum, noise when rolling vol
Call the FCC and your local power company.  
They actually have interference crews that try to fix this kind of thing.

If you are right under the thing, the field strength is such that it overloads the system. Lets say the noise is 100db below the signal in your circuit. But if there is 120db worth of that noise, you get 20db of it in your ear.  
 
The FCC worries when a broadcaster has spurious signals on odd freqs and when it interferes with other services. But I fear just crowding its way into your stuff when you live next door is normal and not somethng the broadcaster can fix short of cutting power to 50 watts.  
 
In radio stations this is a problem. Many stations have their studio somewhere in town with a link to the transmitter. But in many smaller markets, the studio is in the transmitter building at the base of the tower. in these situations they often have to build faraday shielding into the walls of the studio to keep the RF out of the wiring.
