Absolutely, and it would appear that mics using the HC4 and HC5 elements are 
not created equal either. I use a Heil Proset Plus headset with boom mic 
which uses the HC4 and HC5, and have no difficulty in obtaining full rated 
output on all bands from an unmodified K2/100  #3255 without using a 
preamplifier. A preamp would be required if the mic were to be at a greater 
distance from my mouth e.g. a desk mic. BTW 'Headquarters' reports that I 
have a quiet voice.
