TT said they would repair the Omni again for no cost to me....I didn't
inquire about shipping, but am sure glad I have my Ft 990 for a back up
rig.....
It keeps chugging along.....
I suspect...and its beyond my modest test equipment to determine....that
something inside of the Omni is goes into ocillation that normally does
not.
I don't think it has anything to do with my power supply system.
I could pick up a TT power supply to feed the omni, but that would be
counterproductive.

Looks like you're getting plenty of feedback concerning that
oscillation.
My first thought was "what bloney!" Then I realized I had misspelled
bologna. Really, when it comes right down to it....You can't prove or
disprove any of this power supply theory without it costing you
another
trip to TenTec! I mean,,,are you going to get that VI fixed and hook
it
back up to that same system just to see if it blows up again? I think
not!
So then are you going to hook it up to another supply for testing and
run
it for a few days and THEN hook it back up to the other supply just to
see
what happens? Again, I think not. I think you're stuck. TenTec will
never
"approve" your power supply but they will continue to blame it for you
trouble and maybe, just maybe there is some incompatability going on
here.
Who knows...Too expensive to find out!

Subject: [TenTec] Omni VI and power supply occilation???
I recently purchased a used Omni VI that quit transmitting, sent it in
to
TT
for repair and alingment. TT replaced the finals and some other
work...
I recieved the repaired Omni yesterday and wasted no time getting back
on
the air.
This morning....no rf out AGAIN!!! Exact same sympthons as before.
I made a call to the TT repair department, and they said since I run a
homebrew power supply, I may have an ocillation from the power supply
that
is destroying the finals in the Omni.
What ocillation??
I have used this power supply for years. It is currently feeding an FT
990
and uhf/vhf radio without problems. The power supply has fed various
TT hf
rigs thru the years without problem. Is there something unique about
an
Omni
that will not allow it to be used in my station on the existing power
supply??
The power supply is currently hooked up to a pair of absorption mat
deep
cycle batteries with a blocking diode between the B+ and the
batteries. It
has been used this way for quite some time without problem, and the
power
supply alone is capable of 35 amps continous all day long.
TT also tried to tell me this morning that I may have to run the Omni,
when
it gets back from being repaired a second time, on a separate power
supply
that will shut down when it detects ocillation.
Anyone run across this before...thanks....
