[Elecraft] Heil headset with K3

[cqtestk4xs at aol.com]

I've been using a Heil Quiet Phone headset (HC 4 cartridge) from  the very 
first day I got my K3.  It took a bit of trial and error to  find the 
correct settings.  I did not use the monitor to set it up, I used  another xcvr 
listening to the transmitted signal.
 
Not a day goes by that I don't get an unsolicited comment that goes  
something like "excellent audio."  I even got two notices from ARRL  Official 
Observers complimenting the audio.
 
This is not to say that the HC4 element works for everyone's voice,  just 
that it does a good job with mine, which is somewhat low  pitched.
 
My settings: 
Mic gain........ 7
Compression......... 24
audio shaping........I flatten the highs, keep the midrange flat,  and 
boost the lows.
 
Your mileage my vary.
