Hi Gang,

Does anyone have a newer HVAC system with a variable speed drive fan motor or hydronic pump motor? If so, have you experienced any interference on any ham band?

As I get very close to spec'ing an HVAC system for my new QTH I'd like to find out if this is a potential time bomb. To paraphrase an insurance company commercial, 'hey, I just saved a boatload of money on my energy bills, but I cannot hear a signal on the ham bands!'

Thanks es Happy '05.

And for you tower climbers, my safety tip for this year is DON'T TAKE A DIVE IN '05!
