I agree with Duane's position below. This new OMNI-VI+ is the fourth
Ten-Tec transceiver I have owned (after a Corsair-II, -I and OMNI-C),
and the OMNI-VI+ is the clear winner of the birdie-count award. The
other TT rigs had their share of mixer products, but I expected these
anomalies designed-out as the product line evolved. In Ten-Tec's
defense I will say that I have experienced owning ICOM and Kenwood
synthesized rigs, and will probably never purchase another!

As a customer, I don't accept Ten-Tec's position that birdies are
"not...a performance related issue". Any birdie above the noise floor
that obscures a range of frequencies (no matter how small) DOES impact
performance (operation) at or around that range. As for not having a
"fix", I suggest that going back to the drawing board is the real fix
that is needed.   

>From my new OMNI-VI+ received 7-10-97 I am experiencing (antenna
disconnected) an S-5 birdie on 1.999; S-4 on 1.980; S-2 on 3.513; S-1
on 21.330; S-1/S-0 28.121, 28.293 and 28.332; and a wide range of
noise-floor-level birdies from 28.401-28.460 centered about 28.441. Are
these also considered acceptable from an instrument-grade receiver such
as the OMNI-VI?

Since Ten-Tec is up-front on discussing this issue, I would appreciate
Tentec posting a list of "acceptable" birdies for the benefit of our
list members.
