[Elecraft] K3 wierd action.

[PAUL VANOVEREN]

The last couple of days, on 20 meters, 14.070 in data mode for psk31, the TX led lights up intermittently, and the audio make clicking sounds. Of course, while watching the waterfall, the traces are interupted by the radio going into transmit, and I can not print the data on the screen. I am using HRD and DM 780 and have been operating for the last yr and a half with no problems. I powered the radio off and the power supply off and when turning on the ps and the K3, I get an error message on the B vfo line. ERR-Key, and then the banner scrolls and the error message goes away. I cannot find in the owners manual any reference to "ERR KEY".  When I switch the K3 to the "Test Mode", the TX led does not light of course, but the traces continue to be interrupted by the radio going into transmit.. As far as I can tell, this behavior does not happen in any other mode. The K3 is serial # 758 and the firmware is 3.11 and the DSP is 2.15. Anyone have a suggestion of something I might check.
