Meter reads SWR only on transmit - the drive and alc interact -
set ALC, then on CW, set drive for LED to light up,
on SSB to light up, but flash with speech, not stay on all time
- On a number of the OMNi A,B, and my C, there are times that the
diodes in the ALC circuitry fail and you cant really regulate power
out -
check manual for the two diodes back to back for ALC circuitry - might
need to replace both.

I am trying to help a young missionary friend with a Omni D (series
B from
what I can tell from a distance) with a problem. The transmitter
keeps
intermittently shutting down, even when running only about 25 watts
(at
least that is what he thinks he is running). It has been a long time
since I
have owned an Omni D, and since I am so forgetful, I need help in
what could
be causing this. He has checked his feed line to a triband beam he
is using
and all seems to be fine. The rig was at his remote location when he
got
there, along with the antenna and feedline. Does the Omni D meter
read
relative power out only, or does it also read SWR or reflected
power? Hoe
does the drive and alc control interact? What could cause this
problem other
than high SWR? Any insight will be appreciated.- Dan N5NBK
