What is causing my my seemingly odd occurrence of a low SWR and a high current shutdown on my K3 ? It just happened this morning and is very worrisome.
Freq:  14.055SWR:  1.3:1Antenna:  OCF dipoleSending Dits: Random Hi Curr warning for 45 sec and then a shutdownSending Dahs: Random Hi Curr warning for 10 sec and then a shutdownPower Supply: Gamma HPS-1aOther indications: dimming of backlight synched with XMIT approx 5 sec prior to shutdown
Thanks for any help...this is a new issue
