A.R.C. intended the 11-position transmitter select switch to switch mic audio
and PTT lines, and select the desired channel from five on T-11A number 1 or
on T-11A number 2.  The eleventh top-dead-center position selected the interphone,
and usually an INT label will be there.

One channel on a T-11A VHF transmitters would be abandoned to allow the switch
to send mic audio and PTT to the SCR-619 instead.  Often there'll be an FM label
there.  Some used the switch position immediately clockwise from the INT position
for FM selection.

A diagram of this installation using the SCR-619 is shown in many commercial A.R.C.
Type 12 manuals.

My best C-37 was reconditioned to like-new and MFP'd in July 1952.

I like equipment of the Korean War era.  Veterans of that war have always been the
least appreciated by the US population, which was especially inexcusable then, 60
years ago, with a very very large segment of the U.S. being WWII veterans.  You
know...the ones for whom Korea and Vietnam were not *real* wars like *their* WWII.
Whoops...I've gotten off track. :-)
