John,
Which Proset? If it is the ProSet-K2 or a ProSet-iC, then you should
use the electret element Heil uses in their microphone for Icom (those
with an -iC suffix).
OTOH, if you have the normal HC-5 (or HC-4) element in your ProSet, your
choice of the Heil dynamic element will work as you plan - BUT, you will
*not* need the amplifier, just connect the hot mic lead to pin 1 of the
8 pin Foster plug, shield to pin 7, PTT to pin 2 and PTT Return to pin 8.
In any case, with the Heil element in the D-104 head, you do not want
the amplifier we have been talking about - that is only for use with the
original Astatic element.
In other words, if you add the FET amplifier, leave the mic element as
it is now.
