K3 err 12v
Locked
 
|
My tired old K3 (serial 1298) displayed this while I was on RTTY today. The rig works at 10w and under, so I assume that this indicates an issue with the power amp. I checked the book for possible other issues, but came up with either bad connector seating or circuit breaker issues, neither which seem to be the case.
I guess this means a trip back to the factory....hopefully turn around time isn’t too bad.... 73, Ed K6CTA Sent from my iPhone ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Is your power supply sagging?

My K3, of a similar vintage, had the same problem. The URL above describes the problem, and a permanent fix. I didn't trust myself to change the pins on the mother board, so I used a temporary "bypass operation" - jumper wires around the two connectors to the PA. Done with 4 short wires. Elecraft was kind enough to send me pictures of the installation. Has been working well for 7 years. If the radio ever goes back to the factory, they'll change the pins for me.

Ed, I had a similar issue, I too have an early serial number k3. Elecraft
says my rig needs to go in for repairs, there are some old pins on boards that they say need upgrading to solve the power output issue. 73, Barry K6ST Date: Sat, 24 Feb 2018 13:57:05 -0800 From: Ed Schuller <[hidden email]> To: [hidden email] Subject: [Elecraft] K3 err 12v Message-ID: <[hidden email]> Content-Type: text/plain; charset=utf-8 My tired old K3 (serial 1298) displayed this while I was on RTTY today.
