[Elecraft] K3: ERR TXG message with KPA3

[John Unger]

Hi Toby -

Yes, I did turn the KPA3 "on", but thanks for the hint. I should also add 
that all my filters have the correct offsets set (with "-" signs...), and I 
have the 2.7 KHz filter set as the transmit filter for all modes.

I should probable reiterate that the radio calibrates fine on all bands 
with the power level set at 5 Watts.
