[TenTec] OMNI 6 - Interesting problem Encountered during FD

[Glenn]

 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??

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.
