I have the same problem with my radios that I moved to the family room.
All of them have noticeable AC hum when receiving, but once I turned the lobby light on (8 pcs CCFL 7Watts bulbs) he hum goes down so much it is barely noticeable anymore.

What I suspect is that unloaded line that goes by the radios picks up noise whereas loaded (becomes low impedance) doesn't. How exactly the noise is produced, I do not know, but the effect is pronounced.
Possibly repositioning radios/antenna could help.
