I was happily monitoring 14.058 this afternoon when my K2 turned itself off. I cycled the power button and it came on enough to say ELECrAFT and to hear a little audio, and then shut down. Then cycling the switch didn't do anything. Or would do a little.
I figured it was causing F1 to reset. Put it on the bench and sure enough, it's drawing about 5.6A ... the manual is not terribly helpful about diagnosing. I opened it up and started removing boards. Can't really find anything. It would have been too easy if something in the battery charging circuitry had shorted ... With the switch "ON", +12V shows 105 ohms to ground. That can't be good. I'm not really sure how to diagnose this. The PA transistors seem like a place to start: the emitters are grounded, when the switch is OFF, the collectors have about 100 ohms to ground (can that be right?) , the base about 134 ohms. Suggestions would be quite welcome. 73 de chris K6DBG ______________________________________________________________ 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
