Frank and All,

I'm not sure what radio you are using, but on my K3 I get better reports 
using my headset with the IC element than I do with the other one that has 
the HC4/HC5 combo.  Also, with a little manipulation of the internal 
equalizer, you can make the IC element sound very much like the HC4 I would 
think.  But if you still want to try changing it, it wouldn't be a hard 
thing to do.  Just swap out the elements.  On the K3 you would then remove 
the bias by menu change.  On the K2 you would have to lift the jumper 
providing bias to pin 1.
