I would look first for a low voltage under load situation. Maybe a power connector has worked loose.
The VFO frequency is normally saved during the controlled shutdown process initiated by pressing the K3 front panel power button. Pulling the plug doesn't give the firmware a chance to save the VFO frequency in non-volatile storage. 73 de Dick, K6KR -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of John/K8AZT Sent: Friday, May 27, 2011 8:25 AM To: [email protected] Subject: [Elecraft] K3 shutdown My K3 sn1693 has just started exhibiting a troubling problem. Operation in CW when I put key down, the rig shuts off completely. When turning back on, it forgets frequency that was set just prior to shut down. I thought this might be rf in shack, so tried with dummy load and same problem. Any suggestions or has anyone else experienced this behavior? 73, John/K8AZT ______________________________________________________________ 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
