[TenTec] Omni VI- PBT jumping after warm up.

[k8vf_mark at centurytel.net]

All of a sudden My Omni VI(+1) began acting up.

When turned on from a cold start, the PBT is way off,  I must turn it about 
30 degrees to the Counter CLockwise in ALL MODES.
After 5 minutes or so it JUMPS to the "normal" setting (rather it is off 
again and I must re center the control  to hear as I normally would). It 
doesn't drift, it SUDDENLY reverts to its proper state.

If, for example, you were copying a cw station it would disappear and you 
would have to re-center the station with the control.  It works fine until 
turned off and allowed to get cold.

Has  anyone seen this one?  I searched and didn't find any in the archives.

Since it is in all modes, it should narrow it down some.

Thought I would check before I open it up.

Thanks, MArk
