[Elecraft] Transmitter Gain Calibration in the Linux version of the KX3Util

[Joshua Gould]

I tried to run the TX Gain Calibration through the KX3Util and it opened a
splash screen, and then abruptly closed with no other information. I would
say that this is probably a bug, but don't know who to report it to... I
did run the calibration manually and backed up my config file.
