I've got a few PC's in nice metal cases. I can actually run most of my
receivers near the PC without too much problem, as long as the receiver is
powered by batteries. But the instant I hook my sound card to the receiver,
or I run the receiver off of AC power, all the SW bands are filled with
S9 hash generated by the computer and network equipment.

What's the most economical and reasonable way to deal with this? Will
RFC's on the power, ground, and sound lines be good enough? Those snap-
together ferrite cores from Radio Shack help a little, but not
nearly enough. In a few weeks my computer-controlled TenTec
RX-320D arrives and I want everything to be in ship-shape by then.

The computer equipment isn't "just a computer". It's several PC's,
an Ethernet hub, a DSL router, a UPS, etc. By experimenting I've discovered
that the computers themselves aren't so bad... but the networking
stuff (a necessity, I'm afraid) is abysmal.

The situation is serious enough that I'm seriously looking into optical
fiber links... anyone have advice for a low-budget solution that way?
If I can put the RX-320D upstairs away from all the Computer stuff, and
run the audio and RS-232 over optical fiber, I'd be in heaven. While
I know where to start for RS-232 over fiber, I don't know anything
about the available audio-over-fiber options.
