At the ripe old age of nine my K3 developed the ERR 12V problem (in the middle of a contest, of course). I've seen posts here where owners had some trepidation about the difficulty of the fix, which is to inspect and replace some connectors using parts from KPA3CONMDKT.
Relax. It's a bit tedious but it's easy. If you've had any experience at all with through-hole rework I wouldn't hesitate. Have a beefy soldering iron handy just in case. Some of the pins were hard to remove with a small iron. A 40 W iron with 1/4" tip made short work of them. A circuit board vise or a helper to hold the KPAIO3 board while you work on it is also a big plus. Radio and operator are both happy again. 73 and thanks for listening, Carl WS7L ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
