[Elecraft] Microphones for K2/3

[Don Wilhelm]

John,

If your D104 is an older one with the high impedance crystal or ceramic 
element, yes it will not work so well (if at all).

There was an article in QST about a year ago with a circuit design that 
had a very high impedance input and the low impedance output required by 
modern day radios, although a transformer with the right ratio should 
work too.

Another alternative is to change the element in the D104.  Heil offers a 
kit to do just that - check www.heilsound.com for info.

My D104 with an HC5 element draws comments from time to time.
