Default Learn How VoiceMax Increases Your Transmission Range...

You can't change the average level without changing the waveform.


Bovine excrement.

An amplifier will increase the average level, but by increasing all
levels. As many references make clear (some listed below), an
amplifier does NOT change the waveform.

The perfect amplifier or audio processor, would create zero
distortion - no change to the waveform. However, the perfect
circuit does not exist so some distortion will occur in any active
circuit.
This includes circuits already in the radio.

A processor may be any circuit that carries out the process the
designer (or marketing person) has decided on. This could be as
simple as an amplifier... it is carrying out a process.

A processor which simply amplifies all signals and clips the higher
levels can produce much distortion. A well designed and adjusted
processor could produce little more distortion than a simple
amplifier.


The question is whether "Telstar" and "well designed" go together. I
would like to see an independent review from someone without
an axe to grind.
