[Elecraft] K3 Band changing...

Many (many, many) years ago my station consisted of a Heathkit Apache
TX1 transmitter, Mohawk RX-1 receiver, and SB-10 SSB adapter.  I figured
that I had to switch or adjust a minimum of ---12--- controls to change
bands.  If I needed to change between LSB and USB, add two more for a
total of 14.  And that does not include switching antennas and changing
the dial frequency if required (on both transmitter and receiver).

That also does not include my 6 and 2 meter transverters.

In those days I thought twice before deciding to change bands.  :=)

On the other hand, the SB-10 phasing-type SSB exciter had absolutely
WONDERFUL-sounding audio.  I got unsolicited compliments on nearly every
QSO.

P.S. The list as I recall it:

TX-1:  Bandswitch
       Tune/operate switch
       Driver tuning
       Driver gain
       Plate tuning
       Plate loading
RX-1:  Bandswitch
       Antenna trimmer
SB-10: Bandswitch
       Carrier null #1
       Carrier null #2
       Tuning
