I don't think people want to screw with cutting or hacking their radio. I think
you would sell more as an external box. If amplifiers were this way, they would
never sell. That is why people buy them separately, granted, the size would have
some effect. But you can still get stinger boards.
Revisit the idea.


There are certainly pros & cons with either approach. One big problem
in the external design is the need for a battery. Our



MPD.


feeling was that
things with batteries can be problematic... and require additional
monitoring to make sure the unit is functioning on a daily basis. This
increased "battery vigilance" was one of the main reasons the internal
design was chosen.



Power mics have batteries but people still buy them. Or why not tap 12
volts from the power leads to the radio? If the box is so great I'm
sure people would be willing to do -that- much.


Another issue is definately the radio's internal
limiter. On most radios... this is factory set at around 85% possible
modulation.



Wrong. They are set at the factory for 95 to 98% modulation, as per
just about every service manual I've ever seen. And that's a lot of
manuals. An additional 2 to 5% is, for all practical purposes,
insignificant, translating to a peak power increase of less than 1%.


If you want to take full advantage of the VoiceMax 100%
constant modulation capability... the radios limiter needs to be
adjusted/disabled. The VoiceMax has built in limiting... so a
redundant system is not needed.



Wrong. The limiter in the radio is set for the specific radio, and is
usually integrated into the audio AGC that's already built into the
radio (which makes your processor somewhat redundant except for the
noise gate). Disabling the internal limiter and using an external
limiter will almost certainly result in clipping, especially when the
person setting it has no calibration equipment.... that is, assuming
your processor's limiter can be adjusted. Can it?


However, if the limiter in the set is
not adjusted/disabled... VoiceMax will still increase and maintain the
modulation to whatever the radio's internal limiter is set to...
usally aroud 85% as I said before. It sounds like you have no plans to
open your radio... so VoiceMax is not for you.



It sounds like you have no plans to open and read a few service
manuals and find out how these radios already work.
