The Plus only adds the designed-in DSP and the additional 9 Mhz filter.

>You have to decide how much 'faith' you put into either QST or CQ reviews
of ANY radio. My personal opinion is that anyone who 'bitches' about
birdies from any receiver whose antenna is disconnected, well, lets just
say their elevator does not go all the way to the top! I've never known of
any circuit designer, who must build a 'cost-effective' radio, who would
design the front end of a receiver to operate properly into an
open-circuit. It can be done, but it would require an isolator at the front
end, which would only add about $1000 to the cost of the receiver. The ONLY
test (my opinion) you can perform that means anything to you, is to put the
radio on your desk and operate it in YOUR environment.

>Before you discard the idea of the Plus' on-board DSP, consider the fact
that your Timewave was designed to operate with EVERY radio, the
designed-in DSP for the Plus was designed for Ten-Tec by a company that
designs, produces, and sells DSP boxes; the difference here is the Plus DSP
was designed specifically to operate WITH the circuitry of the OMNI
receiver, meaning it's design can be optimized to it's one and only
operating environment.

>That's true. I've had my Omni 6 for almost six years and I've had my
Corsair II for eight years, and if these things EVER break, I really will
need TT's world-class service. I also own a Titan amp, and since I often
run high-speed CW, I have a lot of (self-induced) problems with the relays.
Ten-Tec always has a very knowledgable person to talk with you on the
telephone and they never hesitate to send you a part or a board, and then
you return your defective component. Unless you have some real catistrophic
failure, you will never have to send your radio to them for repair; and
when you do, you can expect typically two to three week turn-around time,
not two to three months that is experienced with other manufacturers.

>>Any general comments from Omni VI owners and comparisons with other

>There are no other 'high-end' radios that compare with the Omni 6. When I
bought my Omni 6, I owned an Icom IC-781; after comparing the two radios
side by side, on my operating desk, I sold the IC-781. There was no huge
difference between the two, just that when trying to pull out weak CW DX
signals on 80 and 40 mtrs, I found I could sometimes read them with the
Omni, but could not with the 781. The trade off I made was the 781 could
run QSK at any speed you want to run, the Omni will not run CW at speeds
over about 70 wpm. The other trade off I made was the cost of an Omni was
about $2800 (with P.S. & filters) and the cost of the 781 was over $6000!
