Carl,

Ben's absolutely right, that's RF getting into the radio.  If you're using 
the remote it may be getting in that way.  You may even be able to affect it 
by putting your hand on the side of the remote while it's happening.  Anyway, 
just unplug everything - remote, computer cable, etc. - and work through this 
by process of elimination.  

Keep cables short, reposition everything, try ferrite beads on the cables if 
you have to.  And while you're at it, as long as I have the podium:  break up 
ground loops in the transmission line with coiled coax or line isolators in 
the appropriate places, use a short ground strap to a very deep and isolated 
ground rod, and connect all straps between your equipment to one central 
point on your tuner or the rig instead of connecting them at different points 
along the main strap.  

There recently was a long thread on this subject here on this list.  Ten-Tec 
rigs are notoriously sensitive to RF.  And when you also have connections to 
a computer and other accessories there are that many more avenues for it to 
get into the radio.  

Here come the passions:  "It's the price we pay for the superior features in 
the rest of the radio!"  But my Jupiter did the exact same thing, and my 
Pegasus actually shut itself down at one point.....yet when I placed my 1984 
Yaesu FT-102 with remote VFO, external speaker, and everything else in the 
exact same postions as my Jupiter setup, the '102 basically just said "What 
RF?".....   (I'm going to duck now.)
