[Elecraft] [K2] HiCur problem

2011-02-12 Thread Brian Denley
I am getting hi current message into a 50 ohm dummy load for any setting over 1 watt (even 1 watt is drawing well over 3 amps). If I try to set the power output higher, the K2 clicks off and resets. In previous tests, I could put 10 watts into the same load with out any problem. Any ideas on
