[Elecraft] K3 needs survey -- firmware and application software

[Guy Olinger K2AV]

I was going to say, all of that being complained about, can be set any
way you want.  Try the SHIFT control on the front panel. Set the
crossover *anywhere you want it*.  The SHIFT setting is remembered by
mode.

Being able to hear down there was specifically requested by some who
do not share your tastes. In the past the firmware would NOT ALLOW
that degree of downward shift.  Now both of you can now set it like
you want it.

73, Guy.
