Good story Don... Sorry you had to deal with that during FD... Hi Hi
I started out using my Omni 7 during FD this year but swapped back over to my
Omni 6+ with the INRAD filters and Roofing mod.
THe Omni 7 is a great radio and I really enjoy it but for CW contesting, the
Omni 6 with the INRAD stuff is hard to top.
Personally, the DSP derived IF/AF path leaves something to be desired, at least
to me, when it comes to trying to separate CW signals during a contest mode.
With the more analog path from the O6, I seem to be able to differentiate
signals a little better, especially when trying to listen to the pitch of one
signal against 2 or 3 others in the same pass band.
Have others noticed the same??

Subject: [TenTec] OMNI 6 - Interesting problem Encountered during FD
Murphy's law rules field day - ALWAYS!
I volunteered my Omni 6 for use at my club's FD outing. We ran the radio off
a battery. Turns out the stud on the negative post of the battery did not
have threads all the way down the post.
When I hooked up the radio I failed to notice I had a marginal connection on
the negative post to my cable harness ring lug.
Anyways about an hour or two into the contest one of my CW ops to me in a
panic saying that they just lost power to the radio. I'm thinking crap! I
only put a 20A fuse in that harness and it just blew on me. (yes, I know I
should have been using one of those over priced magnetically activated
circuit breakers!)
Turned out the lug was not securely tightened down. The radio did not like
that - fixed the connection - the radio resumed normal operation - well sort
of.
Turns out that my OMNI 6 did not like that kind of a shut down and somehow
it did a "master rest" and reverted back to the factory defaults.
Just a strange behavior that I noticed, it took a little bit of time to
figure out that everything got wiped and the radio went back to square one.
As a side note, one CW, with a full load of filters in both IF's plus the
INRAD roofing filter mod, I was able to run on the low end of 20 meter CW
with the 20M SSB guys running too. I heard some interference but it was
completely livable and I never lost QSO do to overload. The OMNI 6's
receiver held up just fine.
