Mike- I should think a slightly higher voltage as you listed would be fine, as
current drops with a rise in supply VDC. It is well within specs. I would be
sure no ancillary equipment (Other than Mic and/or key and dummy load) are
plugged in, and see if the situation changes. I would also measure that supply
voltage with a meter (Scope to look for excessive ripple would be better) at
the rig. (In-line fuses/fuse holders have been known to cause these type of
erratics lately on other equipment..... be sure to eliminate them as a cause.)
If problem persists with rig in free air, I am out of ideas for now. Please
report back to the list as you have time.

hmmm. The Alinco DM-340MV analog 12 power suppy might have
been bumped up to
slightly over 14v on its adjustment knob. i've lowered that
to 12v and kept
a small fan blowing over the unit and it seems ok right now
after a 2 hr
test. Makes sense. At this point don't know if it needs the
extra fan
blowing from the back or the lowered input voltage, or
both.
Kinda stupid, I know.
