[Elecraft] Elecraft K2 Microphones?

[Don Wilhelm]

Fred,

As Eric indicated, the K2 microphone configuration header can be
plugged/wired to work with most any microphone having an 8 pin mic plug.

Obtaining a microphone is easy - if you want to go the inexpensive route,
pick up a CB microphone, they are plentiful and if it doesn't come with an 8
pin plug, get one of those too - Radio Shack used to have them and the first
page of a Google search for '8 pin microphone plug' yielded over 4 sources
at various prices.
If you must rewire the mic plug, you can choose whichever pinout that you
wish and plug the mic configuration header accordingly (I recommend the
Elecraft 'straight across' jumpering with or without the resistor on the mic
jack).

Speaking of the resistor the mic jack, it is needed for those mics
containing an electret type mic element - if the mic element is dynamic, you
should not install it.

One inexpensive method of getting a good working mic is to find a
non-functioning mic and install an electret mic element in the mic head - I
have obtained mic elements from Marlin P Jones & Associates in the past
www.mpja.com
I have re-furbished several mics in that manner - I have a collection of
dynamics and electret types that I use to test the K2s that I build - I can
plug in the one that most closely matches the configuration my client wants
installed - they all work just fine and most of them are from salvaged mic
heads I have acquired inexpensively in various places.

If you do not fancy doing your own microphone from a hamfest 'grabbox'
collection, some folks have found the Ten-Tec mike to work fine, you can
order a mic from Heil wired for Kenwood (similar to Elecraft wiring), or
order a new mic for most any other transceiver on the amateur market - the
KSB2 instructions will indicate how to wire the configuration header.
