There is no comparison between different units, just your regular spam for a
product people do NOT need in modern radios. Modern radios have all that
built in and an older radio would not benefit from it.

Thanks for your comment Vince. Do you really think that people would
pay $40 for something on ebay that didn't work right... and then leave
positive feedback? I hardly think that's likely. The feedback you have
seen is most likely the result of customers with a non-technical

But as far as getting as much swing... that would be a neat trick with

To get the average modulation to 100% then you have to be

It maybe possible to get to 100% average modulation without
overmodulation. Still such a signal is really unitelligable and not
worth the effort to achieve it. A voice so compressed that the peakto
average amplitudes are equal will more than likely yield a totally
unitelligable signal.

I also doubt the claims of 100% average modulation. A decent signal
would have about 50% average modulation. After that, you have nothing
but a trashy signal in my opinion. Also the claims of double the power
are truley absurd.

You can modulate over 100% on positive peaks, assuming the power
supplied to the final final amp stage being modulated can handle the
extra power without clipping the envelope, but you can't go over 100%
on negative peaks without distortion. So to get an average modulation
of 100% with reasonable signal quality you would have to over modulate
on positive peaks and never go over 100% on negative peaks. I doubt
your processor nor any cb can handle that. So you can't just "hold the

Absolute nonsense. Why do you think that sustaining 100% modulation
will render the signal unintelligible? The modulation percentage has
to do with the level of modulation applied to the transmitter. As long
as you stay below overmodulation (100%) then if the modulation signal
has not been clipped... or waveshape altered in any way except size...

Yes there is was a technique used in the early days of AM called
supermodulation. That is where the positive peaks of the wavform could
exceed 100% but the negative peaks still cannot.

This is still not yielding an average of 100%.

Here is the jeopardy question for you:

Name the only signal that has the same value for its peak and average
value?

Now if you can answer that correctly, then you will understand why a
modulating signal that yields both 100% modulation on its peak and its
average is unitelligable.

If you answer that then we might go onto electronics for $200.

There's no swang with FM CB. No swang, no "talk power", no
bandwidth for speech processors... and no point to having one.

FM has a constant carrier level. You cannot see the deviation
on a scope, and very few people here have deviation meters.
That includes CB shops, so there is very little chance that
they will be correctly set to the legal maximum deviation.

With just 10KHz spacing, FM CB is extremely open to distortion
and splatter problems.
Those who do not totally distort or splatter, may well do so on
their peaks. The odd short farting noise may not be a problem,
but what if they are set to a constant max?
Obviously, they will then constantly distort and take out other
channels.

The UK has been there, seen it... and we have the T-shirts
to prove it.

I will not argue with those who whimper on about
"talk power" on AM and SSB, but FM simply does
not work by "talk power".
With FM, getting your voice heard over distance
is NOT done by increasing audio. That just distorts
and splatters.

There is a solution, and it does not use processing or
expensive circuits. I have often used the method to
great effect, at a cost of pennies.
I wonder if the Griff man can educate the group on
this method.
Ah, but wait, if Brian tells us how to do this for pennies,
how will he sell his FM splatter box to people in the UK?

Of course not, FM has a constant carrier level.

Besides which, anything which doubles the power of a
UK CB is ILLEGAL. Any deviation in power is also
illegal - only the frequency or phase may deviate.

People in the UK have previously been fooled by "talk power"
claims from the US of A, not knowing that it does NOT apply
to their FM CBs.
The results were chaos... channels wiped out all over the place.

You should either moderate your claims, allowing for the

Listen carefully, Griff. I understand that, being a Yank,

So, please allow me to inform you of some very important
facts...


UK CB is FM only.

There is no "talk power" with FM, it is a constant carrier
level (unless some tw@t has f'ked the radio up).

Increasing audio level does NOT increase the distance
of your signal.

There are only 10KHz between channels.
FM withing 10KHz spacing is a f'king tight fit.

So tight that the legal deviation level was reduced
in an attempt to stop the splatter problems.

So tight, that the latest radios must have very narrow
receive bandwidth to pass the test - yes, they must be
tested by government approved labs before being
legal here.

This narrow bandwidth will distort the signal of anyone
attempting to increase their transmitted audio.
This distrotion will not show on an oscilloscope or other
test device, as it is generated within the legal FM CB
receiver.


We have had several years where such devices were used
on FM CB, and the results were distortion and splattering
of other channels.
One person I knew actually got complaints of "bleedover"
from 20 to 30 miles away... she became famous for it
across a large part of the next county.

While specific equipment may not be illegal here, radios
pass their test with the original microphone. Adding a speech
processor may invalidate that approval - making the owner
open to prosecution for any interference caused.


Read my lips...
With FM CB, speech processors are worse than pointless... they
cause distortion and interference without any real gain.

If you don't have enough freq deviation... you will not get out well

Yes... Voicemax has an adjustable fast-acting limiter. During the set
up (see http://www.telstar-electronics.com/VoiceMax%20B.pdf) this
limiter is adjusted so the output envelope (AM) is at 100% modulation
during speech. On FM... it's obviously the deviation that is set for
the maximum allowable bandwidth. VoiceMax will then hold these levels
from then on... regardless of the speech input level. The one
exception is below the point where the user adjusts the noise-gate
threshold. This is a point... below which the audio is muted
significanly. This is a necessary feature in a very high gain (+60dB)
AGC circuit to eliminate amplifying low level background noise to
limiting levels. So what you end up with is very potent undistorted
audio... with no background hissing. This is extremely effective in a
mobile environment.

You're catching on. With VoiceMax... once you exceed the noise gate
threshold... the output of the AM(DSB) radio goes from 0% to 100%
modulation while you're speaking. This effectively doubles the output
power and holds it there while above the threshold. Therefore, the
only power shift you would see is when you transition above and below
the noise gate threshold.

(AM) is at 100% modulation during speech.

Stop dodging the question...
It will hold it at whatever maximum modulation level the
"screwdriver expert" has set the radio at, right?
The 100% is only if the person has correctly adjusted the
radio to give 100% maximum, right?

If - due to lack of equipment, knowledge, or both - the
person sets the radio to over-modulate or splatter, the
voicmax will ensure a constant over-deviation or
splattering. No let-up.

Not only is it possible for a radio to overmodulate with
your product installed but, with the lack of technical
knowledge and proper test equipment that is common
with CB, it is extremely likely.


Let me get this right...
Modulation without swing... the carrier is AM modulated,
without any "swing" in the output?

No swing, a constant output level. Yet you have AM
modulation... output level swing.

As you appear to have ducked this one, I have to assume that
either the question went over your head or you didn't want
to admit to something.
In case it was the first reason, I will try dumbing it down...

Amplitude Modulation... The output level "swings" above
and below the carrier level.

Get it yet?

If the output level does not swing, then you have a constant
amplitude... no amplitude modulation.
No amplitude modulation = no audio. Unless, of course,
you are using FM.

worth the effort to achieve it. A voice so compressed that the peakto
average amplitudes are equal will more than likely yield a totally
unitelligable signal.


THE IDEA THAT SUSTAINING 100% MODULATION MAKES
SOMETHING HARDER FOR THE HUMAN MIND TO INTERPRET
IS ABSOLUTELY REDICULOUS. I FIND THE THE CONCEPT
THAT IT CAN MAKE A PERSON'S BRAIN ACHE JUST TRYING
TO UNDERSTAND SUCH SIGNALS JUST COMPLETELY TOTALLY
AND UTTERLY INCOMPREHENSIBLE. I HAVE NEVER HEARD
SUCH ABSOLUTE DRIVEL DURING MY ENTIRE EXISTANCE.
DECIBEL LEVEL IS EVERYTHING AND I GO AROUND SHOUTING
ALL THE TIME.

Ah, but wait, if Brian tells us how to do this for pennies,
how will he sell his FM splatter box to people in the UK?

Maybe I really could take some lessons from The Griffter.

I have spent years giving people good honest advice,
rather than tell them whatever they need to hear
to part with more cash.


And where has it got me?
I have been refused a job with a retailer, on the basis I
was too honest. As the advert said, they wanted an
"amateur actor" to BS customers.
And then there was the retailer who said that I was
"over-qualified", they were hoping for someone a little
more dumb.

I could even have been an Amateur... but I went and
admitted to having a father.

Speaking of Father; he can lie, cheat, bend reality and
scam his way into anything. I believe that it against his
religion to tell the truth on an application form.
He was once caught out lying in a job application but,
as it was at an estate agents, the unabashed use of the
above methods convinced them that he was the man
for the job.


If only I could be a little more like The Griffter,
maybe I could also live his wonderful lifestyle.
Mmmmm, cheese toasties.

Absolute rubbish...
If you don't have enough freq deviation... you will not get
out well on FM... and your range will be decreased.

Please, Brian, don't try telling a granny how to suck eggs.

We have had FM CB here for many years. So, I talk
not just from the theory, but from knowledge and
experience of FM CB in use and the legal situation
in this country.


Let's make this very simple for you...

Our CBs have a maximum LEGAL deviation.
This maximum is set to stop adjacent channel
interference - which DID occur on a grand
scale when the limit was higher.

UK CB radios are adjusted, and government
tested, to meet that standard.
This includes both deviation and, as the law
requires, the receiver bandwidth.

As these radios are tested before approval,
adding any internal board that alters the power,
frequencies, deviation or any other tested
specification may invalidate the approval and
make the complete radio illegal for use on
the CB band.


I suggest you review
http://en.wikipedia.org/wiki/Frequen...dulation_index
for details.

This coming from someone who, by his own admission,
cannot see how modifying the waveform suggests that
there will be distortion.
lol... lmfao.

I know about FM, modulation index, Bessel function and
sidebands.
I may not flaunt my training, qualifications and experience,
but some of us understand that this is a CB group and leave
such things at the door.

May I suggest that *you* learn a little theory? Maybe a
little on FM sidebands, so that you can see how precarious
the balance is between your notional "talk power" and the
available bandwidth of UK CB channels.

While you are at it, if you intend to target the UK
market, I would suggest that you read up on the
rules and standards.


Bottom line... if you can hold the optimum deviation
level on FM... you will get out better without splattering.

No, the bottom line is that, not only has the cheap method
worked much better on FM CB than a speech processor, it
has long been used in broadcast radio and even sound
recording.


This is extremely effective in a mobile environment.

Did you know that, here in the UK, the worst offenders
for splatter are often the truck drivers? But this could
be about to change, as CADS becomes widespread.

CADS allows the broadcast of any material - including
chanting, singing and music - on the Citizens Band. That,
with it's wide range, high frequencies, etc. is expected
to have quite an impact on splatter.

Giving either of these groups of people one of your
toys can only make matters worse. But what do you
care beyond making a fast Buck? You will not be
the one clearing up any of the mess.


Regards,
Peter.

** NOTE:
The above is not intended as an insult to any
customers or groups. CB enthusiasts only use what
some "rig doctor" or shop sells them.
The blame is clearly with those giving them bad
advice or a "supertune" just to get their money.

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.

Other Processors Have a Problem...
Other speech processors use a low-cost "audio clipping" approach to
achieve compression. While this method is economical for the
manufacturer, clipping distorts the original signal and sounds fuzzy
on the air. What these types of audio processors gain in volume, they
lose in voice intelligibility.

VoiceMax is Different...
VoiceMax uses a sophisticated AGC (Automatic Gain Control) circuit
that installs inside your transceiver to hold the audio level
constant, with less than 1% harmonic distortion. No "clipping" type
processor can come close to this low distortion level. Whether you're
whispering or shouting, VoiceMax holds your transceiver at 100%
modulation allowing you to punch through heavy channel traffic without
sacrificing voice clarity. VoiceMax incorporates a feature not offered
on other processors. The adjustable noise gate allows the user to
block unwanted ambient background sounds. This feature is especially
helpful in mobile environments where wind and road noise can be an
issue. VoiceMax works with your non-amplified dynamic microphone to
give you tremendous audio punch without all the background noise
associated with power microphones.

With all that, the dang thing is nothng more than a fancy speech
compressor. I don't care how much fluff you want to put around it. It
is still a speech compressor.
