Elecraft does sell a Heil Proset-K2 with the iC element. However, like any electret element it requires some TX EQ to be effective. The low end typically needs to be rolled off [-6 dB @ 200 Hz, -16 @ 100 and 50 Hz] to prevent "rumble" and wasted transmit power while the high end generally needs boost [+3 dB @ 1600, +5 dB at 2400, +6 dB at 3200] for "articulation" (as paging and PA system designers have known for decades).

I have a new Heil ProSet 7 with the regular HC-7 element. A friend of mine told me that that is the wrong element and that I should have gotten the IC electret element.
