Bob,

There is no master reference TCXO or crystal oven in the Omni V as in the Omni VI.

And as the frequency display is not a frequency counter as in the Corsair II, the display and the actual frequency of the radio as controlled by the L/O will change relative to each other as its temperature of the Omni V changes while in use. It's frustrating to some and not to others. No amount of cleaning of contacts or variable caps etc, will materially improve this condition.

The calibration feature of the N4PY V.9 chip will allow for operator compensation for this situation by freezing the display while you tune the radio for better accuracy on the fly. The N4PY V.9 chip is a "must have" for the Omni V.

IMO this frequency display without a reference frequency control provision was a foolish engineering/design decision and compromised the Omni V which otherwise is a great radio and IMO superior to the Omni VI in its RX audio quality. The exclusion of a RIT/XIT control also caused it to lose appeal with many operators. But I still have mine and do like it to this day.

I had long discussions with Don Proudy of TT service (who left the company several years ago) about all of these Omni V issues. He was the Jedi Master of the Corsair, CII. Omni V and Omni VI. At his continued suggestion, TT mgmt. finally relented and substituted the fluky crystal oven in the early Omni VI's with a TCXO in its later production runs. His departure resulted in a loss of a lot of practical knowledge and experience with all of these radios.

I have performed many great mods to my Omni V and despite its design warts which are real and many, it still outperforms many radios of current times in the quality of receive audio and ease of use.

And finally as I responded on this forum back in late October before I sold my Omni VII, whose firmware revisions have still not been forthcoming as promised, what is TT up to today? It's still a mystery to me.

N1LQ-Dave
