[TenTec] Mode 3 upgrade.....

[Bill Cotter]

Hi Walt,

I bought a new OMNI-6+ in August and had the same trouble with
spurious resets.

I initially had problems with severe birdies, in particular on 10m.
The first trip to TT fixed all the birdie problems with additional
board grounding and moving wires around. When it came back all the
birdies were either down in the noise floor or gone. 

The occasional reset problem was hidden by a persistent problem
with the overvoltage board (relays oscillated upon power up for
.5sec). A trip to TT fixed the OV problem with a board replacement.
When it returned the OV problem was cured, but the radio reset
itself about once or twice week on power-up. Another trip to TT and
they replaced a zener (Z4?) on the CPU board. The rig hasn't reset
since.

Recently, I had a minor problem with the main tuning shaft encoder
sticking and being sluggish to turn part way through rotation.  I
pulled the knob about 1/4"  to eliminate any drag and felt rough
spots during rotation. A call to TT and Paul shipped out a new
encoder which I received a few days later.

I could get miffed about returning the radio several times in six
months, but this was an early serial number for the 6+ line and I
view the radio is a continuing work of art. Don't try to pry it out
of my hands :^)  The help from people like Paul Clinton of TenTec
make the ownership of a TT product a worthwhile investment. And,
the 5-day turn around time each event is a statement of TT's
committment to their customers......Thanks TT.
