I suspect you've discovered Bob Heil's source!
It looks exactly like the HC-5 except the HC-5 has two solder pads The HC-4 has a tiny hole, much smaller than in the photo 73 Frank W3LPL ----- Original Message ----- From: [email protected] To: [email protected] Sent: Monday, February 1, 2021 3:55:52 PM Subject: Re: [Elecraft] Heil HC-5 Taiwanese Equivalent? Used Heil HC-4 and HC-5 elements are very easy to find in the $70 range. I had poor luck getting my HC-4 mic to sound good when I purchased my first Elecraft K3s so I switched to the Heil IC electret element and it sounded much better.

I've emailed the seller to find out more. I have an original HC-5 that produces excellent communications audio with my K3S and it would be nice to find one for the KX3. If anyone has an original HC-5 laying around, please let me know.
