The change was implemented around May of 2009, meaning radios with serial numbers in the low 3000's. If you have a K3/100 more recent than this and you're seeing ERR 12 V, check the Faston terminals on the circuit breaker (they are crimped, and could be soldered or replaced). Also verify

Both the production change and the field modification result in gold- to-gold contacts throughout the 12 V circuit to the PA. Wayne N6KR On Feb 14, 2012, at 9:12 AM, Stewart wrote: I had a look inside my K3 today. Although it is an early one, S/N 307 it has a new RF board with gold

Thanks Wayne, Does the field modification also include changing pins on the KPA3 PCB, as mine are tin plated ? 73 Stewart G3RXQ On Tue, 14 Feb 2012 09:21:31 -0800, Wayne Burdick wrote: Both the production change and the field modification result in gold- to-gold contacts throughout the 12 V

I'm pretty sure, but check with k3support when you order the mod kit. 73, Wayne N6KR On Feb 14, 2012, at 9:35 AM, Stewart wrote: Thanks Wayne, Does the field modification also include changing pins on the KPA3 PCB, as mine are tin plated ? 73 Stewart G3RXQ On Tue, 14 Feb 2012 09:21:31

I was unaware of this, but I'll check with support to see what they did about it. The station may have been running extremely high duty cycle in worst-case temperature/climate conditions. We need to handle this, of course. (Nothing like extended field testing to get the engineering team
