Hi Carmine, I was wondering about the RFI issue myself. It may be a problem here, as I do have a fair amount of RFI in here. I'm using 450 ohm window line connected to baluns in the shack for the antenna feeds. I plan on moving the baluns outside and running coax in, but I was thinking of waiting until the snow melts. I'll use some ferrites on the audio line. Hopefully they'll do the trick. I have terrible RFI problems on my Ethernet connection - in both directions (that is hash/birdies into the receiver and data errors from the transmitter). I need to get some good ferrites for that connection as well.
But its fun trying to figure out how to make all this work well.

Please bear in mind that balanced audio circuits should have a considerably higher immunity to strong RF fields (RFI) than a typical "consumer grade" unbalanced, coax like shielded audio- a.k.a. "RCA or phono type" connections.
