[Elecraft] K3 ERR TXG Message

[Mike Downs]

I get an ERR TXG message after running the high power TX gain procedure on 12, 15, and 17 meter bands. However, both the K3 and my wattmeter show 50 watts output in each case. This error message does not show up on any of the other bands, and it does not show up when operating on any of the bands.

Any thoughts from list members on what the problem might be? Thanks.
