Improve RFI

Fusebox.  It must have been autocorrected. 
Tried switching remotes, no changes.

Tried turning off lights and unplugging everything in the basement, even the components that I want to control with the remote, to see if that changed the RFI indicator, and none of them did.

  What exactly is the Mu Metal supposed to be placed on, if not the Radio switching station?

@mahler123 I’m curious… how is the RFI affecting your system audibly? Are its effects clear to you?

I use Synergistic Research’s Tranquility Base Carbons with excellent results (in full disclosure I am a dealer for them). They are not inexpensive, but they project an electromagnetic field around components to deflect ambient EMI/RFI and suck out trace EMI/RFI within components. In a highly resolving system, these bases add critical improvements in lowering noise floor, removing high frequency hash, and increasing coherence and spatial presentation. 
 

I currently use six of them in my reference system. 

@mahler123,

Are you sure it is RFI and not EMI interference? You will measure a lot of EMI in front of the breakers in the electrical panel. (metal panel door open). Especially large running loads like the outdoors central air conditioner unit, and refrigerator, and other such motor loads when running. It is normal. There is a large EM, Electromagnetic field present around the loaded breakers.

Identify the source of the crud before launching-in to any RF shielding or RF snubbing effort. Start with what tosnc suggests.

At the risk of asking a possibly really stupid question: Have you absolutely ruled out that you might have a defective universal remote? Have you tried using it in your other system?
