Why Do You Need a Speech Processor for Your CB Radio?
Two-way radio communication relies on the modulation contained within
the signal. Maintaining a high modulation level is crucial in
providing the highest possible efficiency from any transmitter
operating on AM, FM, or SSB modes. Two-way radios also rely on
microphones that inherently change audio levels delivered to the
transmitter. This causes transmitter modulation to fluctuate greatly
depending on voice level and pitch. The average modulation of a
typical voice signal is only about 40%. This low percentage applied
to the transmitter, results in less than optimal transmission range.

PURE B--- S---

The peak power is the peak power is the peak power!

Distorting the audio with a speech processor ... distorts the audio.

Distorted audio is distorted audio is distorted audio.

Modulation is supposed to fluctuate greatly. It is supposed to replicate your
voice which fluctuates greatly. If it does not replicate your voice it is by
definition DISTORTION!!

Most processors cause 'nasal' and high pitched sounding audio because our voices
are not 'nasal or high pitched. It is called DISTORTION.

VoiceMax is all about.

I understand DISTORTION quite well! I hold an EE degree, managed an EE design
department for 10 years, and served as Chief Engineer on a major Military System
LGM 118A RS/RV.

Speech compression IS IS IS distortion. PERIOD!
