Yes, when HiCur is detected, the power will be reduced to the level
permitted by the value in the CAL CUR setting = and that value will be
stable.
If HiCur happens on 40 meters (but not 60 meters), and 20 meters (but
not 30 meters), 15 meters (but not 17 meters), and 10 meters (but not on

Don,
Thank you for your recommendations.
D9 is a 1N5711 and checks OK.
A full reset made no difference.
Setting CAL CUR to 3.5 reduces the frequency of the HI-CUR messages, however
with the power control maxed it will still show up sometimes. Note that when
the HI-CUR occurs it is only for a
Steve,
If "hooked up backwards" means that the DC power was connected with
reverse polarity, that will normally cause no harm to the K2 because
there is a series reverse voltage protection diode in the input power
line. The burned trace on the mic jack pin 5 suggests that something

Also, what about the power control pot itself?

Did you check D9 and other components on the RF board that provide the
VRFDET signal?
How did you check "VRFDET, VALC, and VPWR on the control board" if the
transmit power is unstable?

I recently purchased a used K2 (Rev A) from a club that was not working because
it had been “hooked up backward”. That is the best anyone can remember as to
what happened to the radio ~7 years ago…
Currently, the power output as displayed on the radio and on an external power
meter is very unst
