[Elecraft] K3 utility and calibrate RF gain

[ab2tc]

Hi,

I have just installed this and run the "Calibrate RF gain" and I am
impressed with the improvement. My S-meter was accurate at S3 and S9 but
grossly exaggerated beyond S9+10. After calibration it remains accurate at
S3 and S9 (needed no further S meter calibration) and now is much better at
high signal levels. Unfortunately my modified XG1 (normal XG1 + 40dB) had
been left on and run down the battery so I have only been able to test the
higher levels by comparing K3 and LP-Pan/PowerSDR readings on strong 40m AM
stations, but they are quite close. This also much improves the S-meter when
backing off on the RF gain. Very useful improvent and the first one in
months that prompted me to upgrade.
