[Milsurplus] Military - radio transmission

I think everything that could be pretuned was pretuned,
and the dial settings recorded.  i.e., BC-610 had three
pretuned driver frequencies, but the PA had to be tuned.
The BC-375 and BC-191 could be pretuned and recorded.
For aircraft, there was an official dummy load that could
equate to standard antenna configurations.  But, from my
experience very little retuning was ever required.  I doubt
that combat aircraft needed to transmit to a lot of different
places.  The most retuning I've seen is on ships and aircraft
that travel between different countries, and use civilian
radio facilities.  TRIVIA:  Nice, I saw some Navy fixed
transmitters, big and heavy, whose tuning dials had indents
around the edge so that QSY was faster.  WWII stuff,
in service 1952.
