[Elecraft] K3 Power Issues

[W3FPR]

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.

73,

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.
