[Elecraft] K3 Powers Off

[C G]

Hi Mike,

Did you check the powerpole connectors? On both sides: K3 and cable?

I experienced such power down when I changed my original 13.8V cord against a self made one, shorter and with higher cross-section to avoid the voltage loss in the cable. But the insulation was bigger than the powerpole inlet. As a consequence the contact did fit completely to the edge.

Checking the archives it seemed it was a thermal problem so I partially disassembled the radio, cleaned out dust and reseated boards. I checked the p/s and swapped p/s and no change. The problem is not band or antenna dependent. The radio is not even warm when this happens.
