I'm trying this on my K3s, which appears to have the same capability. I have Heil ProSet K2/K3 headphones installed and configured as instructed (1/8" plug to gray AD-1-K adapter jack and 1/4" plug to K3s PHONES jack, with adapter plugged to K3s MIC, and menu MIC SEL set to FP.L bI AS on.
With MIC Gain set to 23, I see red TX LED light continuously as I speak, in normal TX mode. With TX TEST selected, the red LED does not slowly blink, and I can see the ALC meter register 5-6 bars, but hear nothing through my headphones. No doubt I am missing a setting, eh? I appreciate the help! -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Operating-Tip-Using-TX-TEST-to-adjust-speech-controls-and-ALC-level-tp5289738p7620941.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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 Message delivered to [email protected]
