[R-390] High Electrical hash noise level

[Steve Toth]

Bob
Step one completed - emailed Trane via their website.  We'll see what they come back with.
 
I'll pull out my Radio Snack WWV radio and sniff around the furnace and electrical Panel.
I'll also try the short piece of wire on the antenna connection; and check the line with the oscope to see what I've got.  Good ideas, thanks.

In my case, I was getting it through the power circuits.  Drove me batty!

In Steve's case, he going to need some assistance.  Someone with a 
"Selective Frequency Voltmeter", such as an HP-312 is one way to "track".

A handheld battery operated shortwave radio.  Go around the power panel 
- AFTER seeing how bad it is near the furnace.

Disconnect the R-390A antenna, and just leave about a two or three foot 
jumper in the shack attached.  *IF* that still gets the hash, remove it 
and listen again.

Steve - If you have an oscilloscope, OR one you can borrow WITH the 
owner, check the power receptacle where the R-390A is plugged in.

Ultimately, he's going to have to get Trane involved.
