It's really pretty redundant, since almost every radio built since the
1960's has had some form of AGC in the mic line. If he were to use the
noise gate to trigger a keyer relay, use the processor to increase the
peak-to-average level to 40 or 50%, then put it in a box and not lie
about the specs, he could easily sell them for SSB rigs of all types,
ham included. But alas, as you stated befo

Frank... I think you're a little confused... cause you appear to be
using limiter and AGC interchangably. Most radios you speak of use a
limiting circuit... not an AGC. There is a huge difference. A typical
limiter circuit in these radios doesn't have nearly the compression of
AGC/limiter combination. That is because the limiter circuit in these
radios has no absolutely no gain... and can only attenuate the audio
signal on large peaks. That equates to very low compression. The
VoiceMax AGC has about 60dB of gain possible. This accounts for the
very high 15:1 compression ratio. Welcome to the real world.
