[ARC5] [Milsurplus] N-1 Carbon Mic Element and T-17s

[Jim Haynes]

I've often wondered if even a new T-17 is intentionally insensitive so
that the user in the airplane has to shout to be heard over all the
ambient noise.

There are electret replacements for carbon mikes, so you might be
able to fit one of those into the T-17 housing.  I bought some from
Mike Sandman that are intended as replacements for the T1 element in
the G handset used with 500 line telephones.  Somewhere I have the
schematic of what's inside the mike, if you want to try making
your own with an electret element from Radio Shack or elsewhere.

A while back someone pointed out that the Radio Shack electret elements
are wide-band, but there are some others out there that are specialized
narrow band for communication use.
