[TenTec] Omni VI lock problem

[Ken Brown]

Adjusting C31, the 20 MHz oscillator trimmer, seems to have fixed it. I 
don't understand why, since even if it were slightly off frequency I 
would expect the band select xtal oscillators to be locked to it, and 
just as stable as it was. Maybe it was a long way off though and the PLL 
trying to pull them too far. Too bad I didn't look at the freq. counter 
before I tweaked C31.

On my rig C31, the trimmer for the 20 MHz oscillator is on the logic 
board. If I had the upgraded TCXO, would the trimmer be on the TCXO can?
