it sounds like the diodes in the alc circuitry may be going..... easy to
replace, TT will do it too...
for the interim, read the manual on setting the internal alc control, back
it down a bit so the alc led comes on at less power.
It sounds to me that the rig is pulling too much current from the power supply
and the circuitry in the power supply is protecting the rig....

Subject: [TenTec] Please help with touchy OMNI - D
Hi All,
I've had this OMNI - D since 1998, bought from the original owner who had had
it serviced prior to sale, however all the time I've had it, the rig has been
very "touchy" The circuit breaker on the 252M power supply trips often. I was
told by a couple of local TenTec users to consult this list, and that it could
be an issue with the power supply or the ALC circuitry - which I have never
quite understood how to set.
FYI, I am on an 88 ft doublet antenna, fed with ladder line on an MFJ antenna
tuner. I can tune at low power, but when I go above a few watts I am operating
on the edge of shutdown. There is no evidence of stray RF, as I get reports of
a clean signal when I do get on the air.
Also I am currently using the same antenna/tuner setup on a loner Icom rig, and
everything is fine.
Any ideas?
Thanks
