[TenTec] Omni 6+ drift?

[Tom Provost]

I just started using my six plus with a two meter transverter and noticed a 
strange drifting problem. It drifts down in frequency fast enough to be 
annoying for a short while ,then seems to jump up the same amount.That is a 
slow drift down with  fast snap back up. I can stop it (or so it appears)by 
rapidly turning the rig off and on. I noticed something like this before 
but in that case nets on twenty were reading low and if I switched off and 
on they read where they should be...Anyone out there know anything about 
this problem? The receiver on this transverted setup is working very nicely 
and I don't want to give it up but this trouble is noooo good!
