[Elecraft] MH2: microphone

[Eric Swartz - WA6HHQ Elecraft]

They are virtually identical. Same basic mic element, case etc.

We took over manufacturing this when Heil discontinued his OEM version 
suddenly. Apparently he had purchased a group of excess mics and had 
replaced the dynamic element with the Electret element. (Leaving the 
unused dynamic element unused inside the case.) When he ran out he 
suddenly stopped selling them, so we had to locate the manufacturer of 
the plastic cases and spec our own custom version.

For our MH2, the only changes were to eliminate the unused  dynamic 
element left inside the case by Heil, and to improve the foam mounting 
for the electret element for better mechanical support. Overall the two 
mics sound identical. We've bought a very large quantity of these and 
they will be around for some time. :-)

73, Eric
