Fuggedabutit ... Heil will not sell "bare" elements any more as I
found out when the HC5 element went bad in my Proset.

If you want to build your own mic, get one of the inexpensive electret
elements off the web or from Radio Shack.  Let the KX3 provide bias and
assuming it has EQ facilities similar to the K3, use the TX EQ to roll
off the bottom two or three bands and boost the top three by 3, 5 and 6
dB respectively and you will have outstanding audio.
