[Elecraft] New KX3 Beta Firmware, rev. 2.70: Various improvements

[GRANT YOUNGMAN]

Fantastic!!  Thanks, Wayne & co.

Now, could you provide extended TX audio bandwidth on the K3/K3S also?  It would be good to have it as a proper “feature" .. :-)

In addition, peak power output is now displayed, rather than power/4 (25%). This is intended to make the operator aware of the actual output from the radio, which accounts for the observed current drain, stress on dummy loads or antennas, etc.
