Sounds like you may have problem with your power supply. Monitor power supply voltage while you key the rig, see if it stays correct. If it does, check the power cable and see if the APP connectors are fully engaged and not just partially inserted. Try to key it with reduced power output level and see if it still shuts down. Just for sanity check, if possible, try different power supply and/or power cable.

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:Elecraft@mailman.qth.net 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:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
