Re: [Elecraft] K3 ERR 12 V
What is you serial number? Intermittent ERR 12V is one early warning sign of the "burned 12V pins" on the KPAIO3 and KPA3 boards. If you have an early K3 that did not have the "gold pins" on P68B of the KPA3 and J68B of the KPAIO3, I would be making plans to get them changed. 73, ...
