[Elecraft] Knowles HC-3 Mic Element Replacement For Heil, HC-5

[Bob McGraw]

Why not get a mike that DOES perform correctly and one that sounds good 
as well?  And why not learn proper mike technique while at it?   There 
are a multitude of good mikes on the market that really sound good and 
many cost less than $25.

Reminds me of the incident when I was assisting a fellow ham with his 
audio. We tried about everything to no avail.   I suggested if he had a 
different mike that he should try it.  He did, and it sounded great.  I 
told him that it sounded great and his response was; "well, I don't like 
the way it looks"......  Uh, this is radio, not TV.  I can't see it but 
I can sure hear his lousy sounding good looking mike.

Mikes, like about everything else, are designed for a function and 
purpose.  If it doesn't fit your needs as function and/or purpose, then 
you've selected the wrong item for the application. Thus not the fault 
of the item.
