No question that this indicates something is wrong. What size wire (AWG) are you using for DC power? How long is it? Include every part of the wiring between the K3 and the power supply terminals. The DC power lead should be short and fat -- at least #12, #10 is better, no longer than 3 ft total, and shorter is better. Are you SURE there is no problem at a connector? FEEL the connectors after you have transmitted for a while and see if any are warm. What does the K3 voltmeter read when you're receiving but not transmitting? As others have suggested, you should measure the voltage while transmitting with a DC voltmeter, at the power supply terminals, at the K3 itself, and at any intermediate connecting points. If you don't have a DC voltmeter, go buy one. Every ham needs a good one. Most of us have a good one plus a cheapie that we don't mind dropping off the tower. :) Last I looked I had at least six. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
