An external device as you describe was considered during the design
phase... but we decided that an external box (although easier to hook
up initially) was unsightly with all the wires hanging all over, had
mounting issues, and therefore was much less reliable in the long run.
It also has problems accomodating different mic/radio plugs. The
VoiceMax requires the cutting of a single trace within the receiver
and works with any non-amplified dynamic mic. Since it's inside the
rig... you set it up once... and enjoy the benefit each & every
transmission without doing a thing. Hope that answers your comment/
question.

So you can't adjust the threshold on the noise gate? That's pretty
lame. So you set the threshold to trigger at a certain level, like
during normal driving. So what happens when you are towing a boat up a
hill with the windows open? How do you prevent it from chattering like
a chimp with the hiccups? Does it have hysteresis to smooth out the
chatter? If so, how long do you have to hum into the mic before you
can start talking? If not, and you have to set it high enough to
prevent chatter, how loud do you have to speak so your audio isn't
chopped up?

I don't think you've thought through this whole noise gate thing,
Brian. You certainly haven't tested it much under real conditions, if
at all. If you did you wouldn't be selling it.


And BTW, since your non-linear linear has been discontinued, why won't
you post the schematic?

.....monkey at a typewriter..... an even better way to describe the
chatter of a noise gate with a fixed threshold. Very good, Brian!!!

Actually he poses a very interesting question that relates to the
performance of the noise gate and it's response to rapid changing
background noise levels.

I think it is very germane to the evaluation of your product.

The noise gate is not dynamic. It's set at the time of installation to
the anticipated ambient background noise level. It certainly does have
limitations. The S/N ratio of the audio should be high in order to
take full advantage of the gate. This means that talking two feet away
from the mic will not work well. The noise gate is extremely effective
when set with the user speaking directly into the mic from perhaps a
distance of an inch or two. This scenario allows a very large signal
to noise ratio. By setting the gate this way... significant background
noise can be blocked during low/non speech periods. The gate response
time is different depending on which way the gate is going. The time
it takes to break over the gate (quiet to speaking) is around 1mS. The
decay (speaking to quiet mute) is gradual and has been set to around
0.5S. The decay is not an instant transistion (like the break over).
This was done purposely to avoid any choppy effect from muting too
rapidly during normal speech.

In case some small company, in a small European country, are
willing to pay for his discarded designs.
It worked for Fiat.

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 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. Another issue is definately the radio's internal
limiter. On most radios... this is factory set at around 85% possible
modulation. 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. 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's not for me, but I am showing interest, and you're blowing me off. The funny
thing is, I don't have the theory expertise that you, James, or Frank have. But
I am one of the few people that uses CB, that can open the radio up and read
schemtics, and follow directions for mods. I would guess that 95% of the people
still in CB, cannot do this, and would have to take it to a CB shop and have it
installed for anywhere from $30-5-. Why would they do this? As far as the
battery problem, there are a couple options. One is to put 12VDC terminals on
it, or simply use a 12V battery. Hell, the 9V battery in my mike lasts for
years.

Second question is, before I hack into my radio, how much better is this than my
Turner +3B with Speech Compression?
