FW: K2 Microphones

[Dan Barker]

Hear, hear!

I have an "official" MH-2, and the element in it went south. Elecraft says
"Call Bob". Bob's website says send lots of money, the mic, and wait a
while.

The Radio Shack element was $1.95, looks identical to the Heil element, and
works great. The original dynamic element of the mic (from before it got
it's MH-2 nameplate) is still in there disconnected. The little electret
element is beside it.

All works fb.

I picked up a Radio Shack electtret element that I mounted in a hand-held
mobile microphone enclosure. The original enclosure held a dynamic element

I have to admit to operating a tiny bit of SSB.  I had an old friend
(since gone to his reward) who had forgotten the code and I needed to
get on 75 meters to work him.  He gave me one of those Radio Shack
electret elements.

I got a piece of 3/4" or so PVC and a couple of PVC pipe caps, drilled
one cap for the element and stuck it on the pipe.   I drilled the other
for the cable on the other end.  While I was in Radio Shack, I picked up
a cheap but solid mic stand and a little foam gadget that is used to
reduce "plosive" response.  It fit perfectly over the element.  I put a
bias resistor and blocking capacitor in the tube, and hooked it up.  I
painted the thing flat black.

It looked totally professional and got reports equal to or better than
various other mics that I tried.  The total cost was about $10.
