[Elecraft] K3 mystic fault

[Tom (HB9DOD)]

Hi guys,


This weekend as we started Helvetia Contest my friends K3 #293 had a strange problem..

Worked so far with all firmware.

Draws a little over 3 Amps with 12w Output at full output FM on any band.
During "Tune" is seems to tune with 5 watts which i have in my Config

During "SEND" when i go from Low Power to High power above the 12 Watts.. Current increases to 8 Amps but no output more then about 12 Watts


IN SSB ALC Meter gives the right ALC but no output is shown

Monitor is OK as i hear myself

As i do an ATU tune the upper display usually reads swr but now only gives 2 dashes --
ATU is working , relays are clicking and no fault is given by the firmware.

Sometimes it give an error ERR TXG



Receive is OK

Is has all options built in and the latest modifications done...

KRX KAT 100W DVR

What could be wrong here??
All input is welcome...
