I am getting transmitted RF feedback into the K3 when running high power with a headset that uses a condenser element. With an otherwise identical setup, I don't have any problems with either of my two headsets that have dynamic mic elements, using either the front- or the rear-panel mic jacks.
I hear the distortion in the K3's own monitor, but I have confirmed the distortion using my K2 as a second receiver (1" wire in the ANT jack, RF gain near zero, ATT on to prevent front-end overload) and with on-the-air tests with stations hundreds to thousands of miles away. The problem headset is designed for aviation use and, as far as I can tell, uses a shielded mic cable. Has anyone else had and resolved this problem? -- 73 -- Brian -- K1LI ______________________________________________________________ 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
