Thank you Kent and also thanks to Tom N5GE and Ken K3IU for their replies. Downloaded the latest utility but still got the error message on doing the RF gain calibration on the sub rx.
Restarted PC and K3, redownloaded and installed 4.22 f/w and re- performed RF gain calibration. This time no error message. So problem solved but goodness knows why! 73 all and thanks again Geoff G3UCK ----- Original Message ----- From: "K9ZTV" <[email protected]> > Had the same problem in the Fall. > > Solution (for me) was to download the latest firmware into a fresh > directory (no other files), and re-install the latest version of the > Utility. > > Calibration proceeded normally after that. > > 73, > > Kent K9ZTV > K3 #21 ______________________________________________________________ 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
