Arliss,
If you do not have the latest firmware loaded along with the latest K3
Utility, please load the latest and try again. If it continues to fail,
contact [email protected].

Running the low and high power TX gain calibration via the K3 Utility
gave the following result:
"TX Gain calibration failed because power reading did not converge to
a consistent value. 5W calibration failed."
"TX Gain calibration failed because power reading did not converge to
a consistent value. 50 W calibration failed."
The low power calibration failed on 40 meters and stopped there. The
50 W calibration failed on 160 meters and stopped there.
The radio also gave an error message: ERR TXG (Transmit gain constant
out of range).

Arliss,
I would suggest that you run the Transmit Gain Calibration and see if
that improves the situation.

This behavior seems to be >independent of mode and frequency.
