Hi Jerry
I would say that it is probably not tht mechanical part of the PTO. If It
is the rebuild kit which is a good thing to buy while it is still available
will probably not help since it just replaces the grease and wear parts in
the drive. I would think that taping on the tuning knob on any Ten-Tec PTO
of this type would cause a frequency shift since you are moving the screw
drive when you do that. Now if you are really banging on the key when you
send that could be another story =:-)
I would look for something heat sensitive in the circuitry common to the
receive and transmit oscillator frequency generation. I would see how my
Omni C reacts to taping but I blew the final transistors while testing after
rebuilding the PTO I accidentally turned the band switch while key down
which is a no no. I still had the front panel off and got confused.

Subject: [TenTec] Omni C help
Gentlemen,
I have a Omni C and recently I have been getting drifty reports on cw which
is all I use it for. Also, I hear the same drifty sigs on my end too on all
cw signals. When I tap the top or face of the rig nothing happens but if I
tap the tuning knob it shifts in freq. I have been told I need a pto
rebuild. Dont want to send it to TT because I don't want to put much money
in it but if the rebuild is all I need I will do that myself. Any ideas? TIA
and happy new year to all.
