Re: [IRCA] QRM from lights

["Steve" <VE7SL@xxxxxxx>]

It's not the lights but rather the low voltage switching power supply 
converting 120VAc to 12V DC. I had the same thing next door but they let me 
swap them out for 120V halogens rather than the 12V ones. There really is 
not much you can do with these supplies to make them quiet as the signals 
they produce are real and nasty.
