Default VoiceMax is Coming July 22nd... Are You Ready to be Heard?

Beisdes increasing modulation percentage from 85% to 100% gains little
in range or intelligability. Often not worth the effort. Adds about 7%
audio power into the each of the two sidebands. Even if the limiter
section of the modulator section is not disabled adding your
compressor is not going to increase the percentage of modulation. So
why waste the money to buy and install it unless you disable the
radio's internal limiter?


The original radio has the capability of getting to 85% modulation.
This 85% is by no means the average modulation... which is really
around 40% with voice signals. The VoiceMax brings the average
modulation to 100%! That means that every voice... high or low... soft
or loud... will modulate the radio at a constant 100%. I'm in full
agreement with your last statement... if your leave the radio's
limiter untouched... you will only be able to maintain a constant 85%
modulation. Granted, that is a great improvement from the original
radio modulation... but to get full advantage from VoiceMax (the
VoiceMax installation instructions are quite clear on this point)...
you need to adjust or disable the radio's limiter so you're able to
reach the 100% modualtion point. Once there... the VoiceMax has an on-
board adjustable limiter that will hold you precisely at the 100%
level. You can't do any better than that!
