We had 3 K-3’s at our field day QTH this year. Two worked flawlessly, however, mine; #353 developed some front panel issues. I have had no problems with my K3 prior to this. The rig would work as usual for a period of time then with no error messages; the front panel controls would not function normally. Here is a summary of what happens:
Band—cannot switch bands up or down Mode—cannot switch mode Menu and Disp—do not work Xmit and ATU tune-- do not work RX Antàturns on NB Antàturns on NR All potentiometers work Push function of 4 knobs, shift, width, speed/mic, and CMP/PWR do not work VFO A knob—changes VFO A VFO B knob—changes VFO B A/B, REV, AàB—do not work PREàturns on notch, toggles between auto and manual AGCàplays contents of M3 voice keyer when on SSB Xfilàshows M1—M4 in display window NB, NR, NTCH—do not work SPOT—toggles between LO/HI and Shift/Width (shows LO and FC) CWT—toggles PWR and CMP settings in display AFX—toggles between LO/HI and Shift/Width (shows HI and BW) VàM, MàV—do not work M1, M2, M3, M4, REC—do not work RIT, XIT, CLR—do not work None of the long press functions work (yellow labels) I can power the rig off and on. The rig will intermittently begin working properly for a while then the front panel repeats what is described above. We had to remove this rig from the operating position 20 minutes before the start of field day. Heat is not a problem as we were in an air-conditioned room and we had not been generating RF. I am running firmware version 3.19 and reloaded it after the first time the front panel locked. I have looked through the manual but see no mention of these phenomena. Any suggestions would be appreciated. ________________ Jim Kauten, MD [email protected] [email protected] ________________ ______________________________________________________________ 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
