[TenTec] Omni C help

[John Cox]

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.

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.
