John,
You are correct. Sounds like you did a lot of research.
By the time the Omni Series C came along, there were no analogs so there was no
need of Ten-Tec to call it the Omni D, Series C. The whole thing is confusing
to some because it appears the "C" model came after the "D."
I used to own one and always referred to it as the Omni C. Although the Omni C
was the first Ten-Tec to feature the new WARC bands, many people, like myself,
discovered that the 17 meter band emitted some spurs because of the IF
frequency. I understand the IF scheme was later changed in the Delta and
Corsair to eliminate the problem.
