[ARC5] Motorola TMN6054A for Carbon Mike Substitute

[David Stinson]

Been telling myself to try one of these Motorola
TMN6054A mics as many have recommended for, oh,
about 25 years.  Finally ordered one to try.  It
works well with the 24V SCR-274N, but it
motorboats when I try to use it on the 12V TCS.
If I yell into it, the  motorboating will stop,
but then start again next key.  Anyone
investigated this?  Probably a look at both mic
circuits side-by-side would tell but maybe someone
has already looked at this?
