[TenTec] Omni VI tracking

[Art Lewis]

Ken

Its about 50Hz off on SSB. Seems like a strange problem because, like you 
said, they use the same oscillators. The receiver is high. Not sure what to 
look at. Rig seems to perform fine in all other respects. Don't want to 
adjust anything without knowing what is happening.
