Corky,
If you can adjust the power supply output, set it to 14.3 volts and see
if the problems go away.
Measure at the K3, not at the power supply.
Eliminate your power distribution system and connect the K3/P3 direct to
the power supply.
Let us know if that helps.

I was having trouble with my P3 going into brownout mode when transmitting 50
Watt digital. This used to be fine, but seems to have been getting worse over
the past several months. When I monitored the power on the front panel of the
K3 I found it was dropping about 1.5 V when transmitting digital signals. This
would occasionally drop below 12 V and cause the P3 to go to brownout and shut
down.
