Brian, have you been tipping the bottle a bit too much
lately???????????

Sorry Brian. Increasing the power density in the audio spectrum of a
NBFM signal will do jack for transmission range. Simply to put it, to
incease range, you need to increase carrier power. To put it simply,
at the reception end the NBFM signal needs to be 20 dB carrier to
noise ratio or about 12dB SINAD to obtain near full quieting.

All audio power does is increase deviation. Using a compressor on FM
just increase average deviation.

Do you really think that people would pay $40 for something
on ebay that didn't work right... and then leave positive

Every day people are buying products or services that
do not work, then giving positive reports.

Magnetic supports, bands, etc claiming health
benefits. Then there are the cups and devices to
clamp around water pipes, claiming to make water
better for you. Another that, if clamped to your fuel
pipe claims to give your car more miles to the gallon.
Some claims include curing illness and diseases.

How about the "mediums" and ghost hunters who claim
to talk to your dead relatives? Their methods have
been publicly exposed, and they have been proved on
TV to be faking.

Many more products have been suggested as hoaxes,
fakes and scams, in spite of the fact that people claim
that they worked for them.

The craziest one of all has to be the water scam...
Some years back, in an episode of the hit Brit comedy, Only
Fools And Horses, they bottled tap water and sold it as
mineral water.
The British people found this extremely funny... until a large
American drinks company pulled that same scam on the British
public.
They bottled English tap water, gave it labels claiming health
benefits, and sold it at a pound a small bottle... probably the
highest priced "mineral water" in the country.


In spite of public exposure of deception, people continue to
believe in and even recommend such products with reports of
how they worked for them.
Some people are so desperate to believe, they only see what
they want to see - even if it is not really there.



I hardly think that's likely.

Can you say placebo?

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.

They say that the truth hurts, but what really hurts
you is when the facts are made public.

Face it, your bluffs didn't work. You are exposed
as a fake, who simply chants words he heard
somewhere without really knowing what they mean.

That is far beyond any cber's ability. IF they can get it installed
they will crank everything up to the max to make sure they get all the
"swang" on the meter they can and splatter across all channels.

Well... you may be right about the first part... lol
But as far as getting as much swing... that would be a neat trick with
an audio device AGC such as VoiceMax. You see the AGC holds the
modulation up no matter what level the input is... therefore no
swing... just constant maximum modulation output. VoiceMax actually
doubles the power of any CB by taking the average modulation to 100%.

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