[Elecraft] K2 Microphone -- what is it?

[Eric Swartz WA6HHQ - Elecraft]

Hi Hugh,

All of the Heil MH2 microphone shells have an extra unused dynamic element in
them when they arrive at Heil. Heil replaces that element with his higher
quality condenser element that is optimal for the K2. Taking the old one out
could actually damage the enclosure and will change its acoustic properties.
Leaving it there does not degrade the audio. The foam in front of his new
element is part of the acoustic design of the microphone. If none were
there the enclosure would resonate and sound 'hollow'. The foam actually can
pass a significant amount of audio.

We chose this Heil microphone after extensive testing of a number of 
candidates. It was the best of the group. Its audio is punchy and well matched 
to the K2 with an excellent output level. So far we have shipped hundreds of 
the MH2 microphones and the feedback has been excellent. I use one on my 
personal K2 and so does Wayne.
