[Elecraft] Err TXG message

[Victor Rosenthal 4X6GP]

Igor,

Try this: attach the dummy load and then tune the ATU into it. Then 
switch the ATU to BYPASS for the calibration.
I am not sure why this helps, but it is worth a try. This is only for 
the non-S version K3, in which the ATU is not really bypassed.
