[Premium-Rx] "quiet" dimmers

[John USA]

Hi group!

As I near completion of building our new house, I need to address 
radio-related issues and how they interact with the house systems.  While I 
heavily filter the AC feeds and power condition/isolate/regulate voltages, I 
still need to be careful with appliances and controls.

Does anyone out there have recent experience with a light dimmer that can 
operate in the presence of sensitive receivers without causing all sorts of 
RF noise, both radiated and conducted?

Any input most appreciated.
