The behavior of the voltage on its wiper is exactly what you would expect: a smooth transition from 0V to 4.7V for the full travel of the knob from CCW to CW.
So, the question remains, what could cause the very non-linear behavior that I observe with the audio and S meter? This result also renews my curiosity about whether others have observed any non-linearity around the 10 o'clock position of the RF gain when listening to a test signal like an XG1? ----- 73, Stan - KR7C -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Rf-gain-tracking-main-vs-sub-tp5668917p5671487.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
