RFI and EMI help
A few months ago I moved from Raleigh, NC to São Paulo, Brasil.
I was living at my grandmother's for a few moved and finally found an apartment on Avenida Paulista.
Great location except for one MAJOR problem. Avenida Paulista sits along a ridge, making it one of the highest points in the city. As a result every friggin' radio station tower is within a few hundred meters of me. I have the four broadcast largest towers in the city within 200m. My apartment is sitting right smack in the middle.
I have no problems between my Consonance Cyber-800 power amps and my Consonance Eric-Grand speakers.
And so long as I don't have an RCA connected to the power amps I am okay. However the moment I hook up any of the RCA interconnects I have, I get some major RFI and EMI.
Here's what I have as far as cables to work with
a) Cheapo Monster RCA interconnects
b) Cheapo generic RCA interconnects
c) Decent directional Consonance Billie interconnects. The have directionality but I don't know if this means that the copper braided shielding is connected to one of the RCAs or if it is the "snake oil" directionality.

d) homemade 4-wire Litz braid silver interconnects with each of the four wires PTFE insulated and then a braided metal sheath that is soldered to one of the RCAs but not the other (directional).
Is there a way I can modify the homemade cable to solve this boondoggle? Can I unsolder the sheath and add a drain wire? If so, where do I connect the drain wire to?
Is there any solution using "fast" capacitors on the shielding or anything else?
I need the most hardcore RFI & EMI solution you can imagine.
