[Elecraft] Dreaded ERR 12V Message

[John via Elecraft]

 Gerry,

Don's last suggestion and link is almost certainly answers the problem. Having owned two K3's in that serial range, I had the exact same issue with both. Both had the tin connectors. Replaced both with Elecraft supplied gold and no problems since. Elecraft will likely give you the gold connectors.  With the earlier rigs, it's not a question of "if", it's when!

I was not able to operate even at low power until I powered off and then back on. I was able to operate again, but it would intermittently display the message again. I was able to operate fine with 10 watts (after powering off/on) This happened on other bands and on SSB.  I noticed that as I turned the power level clockwise  while listening that the background noise noticeable dropped with the power level went over 12 watts. I also occasionally got the message even while not transmitting.
