Hi Hank, Just removed the K3 from its harness and tested the RCA jack to see if it's shorted; Using the fluke it shows 500 ohms & when the probes are reversed, there's an infinite reading so I'm assuming the diode is intact.
Guess that's not this issue. Thanks for the idea though. 73, Gary KA1J > Gary I had my K3 die in middle of qso - its turned out to be the reverse > polarity diode that hangs from the 12v RCA jack to ground - it shorted dead > (not a damn thing hanging on that RCA nor had there EVER been anything on > it ) so that keeps the FET from letting the radio turn on -- check DCR > from RCA jack to ground - just a chance --Its D35 a SMD 1N4007 or something > like that if I remember - > > GL what a BUMMER -- 73 Hank > > -----Original Message----- > From: Gary Smith > Sent: Friday, January 23, 2015 6:49 PM > To: elecraft@mailman.qth.net > Subject: [Elecraft] K3 Lost power > > Was in the middle of the CQ 160 contest and the K3 shut down.
