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.

I own an RX-320. When I first hooked it up, I used a long wire antenna
which tended to be quite noisy. Was using an old (100mhz) computer with low
quality graphics. Built a folded dipole with (tv) coaxial input to radio.
Installed it in my roof. Everything became quiet.

I have since replaced my computer and monitor (high power, high quality
graphics, high refresh rates, etc.) and everything is still quiet. The
radio is less than 2 feet (as the mosquito flies) from the computer. I
still occasionally use the long wire to monitor the HF band edges and MW/LW
frequencies.

Information on the antenna can be found on Yahoo Rx-320 group
