There have been some reports of transmit drift in early KX3 units, especially modes that are long duration, like JT65. A modification has been made in the firmware that allows for making a custom temperature correction curve that is used to compensate the oscillator as the PA heats up. It changed the situation for me on JT65-HF from one where my transmit signal would vary unacceptably over a 48 second period, to one that is entirely acceptable. The calibration process does require access to a stable signal source (like a K3 that is warmed up and in a steady-temp room). 73, Bob, WB4SON ______________________________________________________________ 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 ______________________________________________________________ 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
