Fwd: [Milsurplus] The TCS question-- Mic Subsitiution

[Mike Clarson]

Just an idea-- Has anyone tried an old Motorola (Motrac/Micor vintage)
Mobile or Base Microphone? These were dynamic microphones with built in
preamp made to directly replace carbon microphones. Some of the Base units
even have an internal gain control. While it is not original, it is a
possible NO MOD solution. Warning: While the connector on some looks like an
Amphenol mic connector, it is keyed differently and will not fit the
Amphenol. --Mike  WV2ZOW

Excerpt

Only one of the emails mentioned using a "carbon telephone insert" which is
better than the original mic used (T17 derivative?).
A british No 8 carbon mic, similar to that used in older type telephones
produces 90-100% modulatoion without the necessity to build a mic pre-amp,
even when running both tubes on A.M. at this location.
Carbon mic quality though!
