John,

Even expensive speakers do that sometimes.  It's tough to predict what will 
fix the problem, especially as it's difficult to figure out how the RF is 
getting in to begin with.  It may even be getting into the sound card and 
being passed along to the speakers.

I had more problems with my TM-G707A, but I have almost no RFI from my 
TM-V71A.  I didn't do anything to the speakers or the antenna, and the new 
radio is installed exactly where the old one was.  The only thing that may 
have changed is the position of some of the coax (not likely), and/or the 
leads running to the power supply, but since the radio is about ten feet 
from the computer, and in another room, and the antenna is outside on the 
roof above the radio room, I don't understand why it works better now.
