Steve:

I will try your suggestions here, including the one of putting the computer 
speakers on a totally different circuit.

In the shack, the computer and radio are on the same circuit, but the amp is 
on a different circuit.

I'm going to try juggling things around here in various configurations to 
see if anything makes a difference.

I did try putting an extra hunk of coax on the DXCC feedline at the 
transmitter as sort of an RF choke, but no joy!

Will keep at it here.

It's Spring Break, and snowing like crazy again, so once I get some other 
stuff done, it will be a good time to play radio later today.

Re: OffTopic: trying to get a PC to play audio through monitor speakers

I had sent this earlier, butmade the mistake of replying to a reply, and
it didn't get to the list:


Tom,

Glad you got the monitor speakers working.  As for the RFI:  These pc
speakers can be a pain sometimes.
   The problem is very often the wall wart sending  power to the
speakers.  Try a ferrite on the cord from the wall wart  and also on the
audio cables.
Sometimes it's better to clamp everything and if the problem is gone,
remove them one at a time until you find which one really solved the
problem.

Try plugging the wall wart into another outlet on a different circuit.
Even if you need to use an extension cord and run it to another room.
Are you running
the amp/radio/pc on the same circuit?  Maybe getting the amp onto a
different  a.c. circuit will help things in the shack.
