[Elecraft] Heil HC-5 Taiwanese Equivalent?

[donovanf at erols.com]

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

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 was looking an original Heil HC-5 microphone element for my KX3 when I

There's no frequency response curve or other information other than a 
comment about the element favoring higher frequencies. 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.
