[TenTec] 544 freq display jumping on TX

[Adam N.]

I have a nice 544 that has a problem where the freq readout jumps around 
while transmitting on some bands (15m comes to mind).  It does not seem 
to be changing my actual output freq.

When I use the remote VFO (for TX and RX) the problem stops.

I've read through the archives on this reflector at some possible causes 
(PTO rebuild, dirty band switch, unstable osc) but I'm not sure which to 
attach first.

Thanks in advance.
