The problem is that it's not consistent.  I did make over 250 QSOs, after 
all.  After re-initing the MMTTY Engine the radio would sometimes get 
stuck in xmit ... but not always.  I did notice that when I turned the 
radio back on that it would retune even though I hadn't changed frequency.

I'll check, but I don't think so.  All the radios go to a copper bar and 
the bar is connected through the patch panel to an 8' ground rod not 10' 
from the station itself.  The computer is only grounded through the 3-wire 
plug so I'm not sure what else I could do there.  I'm thinking that it's 
more like some kind of proximity thing.  Maybe make sure all the audio is 
as far from the RF as possible.
