The iC Electret element is a condenser mic, and requires power from the radio. As far as I know, only Elecraft and Icom radios are designed to do that, so you'd want the Dynamic element. Remember to budget for the correct adaptor and some sort of PTT switch - I personally prefer a footswitch to keep my hands free for logging.

Thank You.
It's been a good few years since I looked at Bob Heil's stuff but there were two choices for the mic inserts. HC-5 was the normal frequency response insert and the HC-4 was the DX insert - a lot sharper sounding audio.
No help here. I also use apple head phones
Yeah, they are nice. I was just hoping to upgrade the hand mic. Then I went down a rabbit hole. So I was thinking when out on the lawn I could go total old man style and use a headset. In the end it still means I have to do something with my HM-31. Maybe I'll just modify the HM-31.
