My K3 has started intermittently going to lower power--usually around 5W. After some online research, I ran the TX calibration in the K3 utility program, and it failed for both high and low power. So clearly something is amiss.One post said Elecraft support had said to reset the TXGN values back to their defaults. Does anyone know what those default settings are?Any chance this is caused by the oxidation issue?FYI here's the failed results from the TX calibration procedure:K3 Tx Gain Calibration data written on 2012-09-25 at 10:48:22K3 Serial Number 03093K3 MCU version 04.51.
