The RS-38 microphone was also used with the GF-11/12 aircraft transmitters.

Didn't realize the RS-38 was so widely used.   Have accumulated a number of
examples over the years and found the "working" percentage to be about the 
same
as old T-17s.   Thing is, the TCS didn't really have an audio chain in the
usual sense, just fed the mic through a transformer directly to the
P-P 1625 grids.     Same thing in the BC-441 and in both cases, unless one 
is
using a very hot mic, modulation is limited to around 50% at normal speech
levels.   The BC-375 even with it's type 10 speech amp stage isn't much 
better,
BTW.
