[Elecraft] K3 Automatic Transmitter Calibration with TXG Error

[Bob DeHaney]

I am performing this procedure with the ATU in Bypass, on K3 S/N 906 using
the very latest versions of all firmware and the K3 utility.  

While performing the 5 Watt calibration at 1.9 MHz I get a good 1.01 VSWR
into my dummy load and an indicated 5 Watts but "Error TXG".

Also on the 5 Watt calibration on 50 MHz I get an "Unexpected result and an
ascii string, with power settled at 4.4 Watts".  The calibration procedure
then concludes and the rig displays "Error TXG".

At 50 Watts the calibration completes successfully with no errors.

What to do?
