I use a two-lead electret element (Radio Shack) wired for Icom . My K2 
mic input is configured for Icom pin-outs and has a 5.6K resistor to 
provide power to the electret's built-in FET preamp. The mic provides 
plenty of output to drive the AF and VOX circuits without any mods to 
the rig.

The Heil HC4/5 elements are dynamic types that produce about 10dB less 
output than most other dynamic mics and usually require the use of a 
preamp to drive the K2. I know some K2 operators have had success with 
them, but I have to shout to make them work with my K2.
