[RFI] An HVAC NO RFI experience

[John K9UWA]

Matt and ALL others posting your RFI report says nothing about the location of 
your antennas as to how far away and how high they are relative to your Furnace 
and or AC system. Matt's report on the Trane furnace is perfect except he too left 
out this most important part. 

A really great report would be something like My Scanning All HF and VHF 
frequency transistor radio make model .. when placed near the furnace hears 
nothing no RFI No Birdies or an SDR where one can watch the waterfall across all 
band frequencies and again the SDR placed near the furnace or AC system. 

I am very glad that TRANE has implemented the RFI changes into their furnaces. 
One of my local friends bought one a few years ago and went through all sorts of 
things before they solved it for him.
