Actually... you're right... VoiceMax doesn't double the power... it
increases the PEP power four times the carrier power on a constant
basis!

Exactly... now where did I hear that... lol
That's what VoiceMax can accomplish!

Some UK shops can now find out how this wonder
product can "double the power" of FM CB radios.
I'll bet you didn't know that you can double the power
of an FM transmitter with a speech processor, huh?

Stop talking nonsense... we both know that the doubling
of power refers only to AM(DSB) signals.

The claims are not aimed at you and I, they are aimed
at CB enthusiasts without technical knowledge or
experience to know the truth.

By making "double your power" claims of "any CB", without
clearly stating that it will not apply to FM CB, you are
misleading the British consumer.
The only possible reason you could have for making those
claims within the UK, or not telling UK consumers that it
does not apply to their CB, is to purposely mislead in an
attempt to boost sales on a false promise.

Naturally, I would hope that I could convince either you
or the shops to drop the false claims within the UK, making
it clear that there is no power gain for FM.
But if not, do the words "Trading Standards" or "Ofcom"
mean anything to you?

However, don't discount the fact that VoiceMax can
increase the usable range of an FM transmitter as well...

And we cannot discount the fact that FM CB is not the
same as broadcast radio. The 10KHz spacing was never
intended for high quality sound, and will not allow it
without splatter.

UK FM CBs are designed, made and tested to do the best
within the available bandwidth. This includes receiver
specifications.
You cannot polish a turd. FM with just 10KHz spacing
is very much a turd.

Like I keep telling you, we have had FM CB for 25 years. We
have had the amps and processors... and the splatter that
goes with them.
I have also worked on many UK CB radios over the years,
and have never needed a speech processor to get better
modulation over distance.

Peter.

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.

Peter... I was just out at your site. I suggest you update your page
http://www.citizensband.radiouk.com/...ics/solder.php to
comply with RoHS.

Maybe you would like to point out which part of the directive
regulates Web design. I'll help you out, name the group...
Large household appliances
Small household appliances
IT &Telecommunications equipment
Consumer equipment
Lighting equipment
Electrical and electronic tools
Toys leisure and sports equipment
Medical devices
Monitoring and control instruments
Automatic dispensers

Then, maybe you could point out which part of the directive
applies to Web masters. Again, I'll help you out... name the
group:
Producers
Retailers and Distributors
Local authorities
Waste management industry
Exporters and reprocessors
Businesses and other non-household users of EEE

Reference:
http://www.dti.gov.uk/innovation/sus...page29048.html

Also, in answering the above, you need to understand that the
WEEE is just a directive. Each member state can make their
own laws based on the suggestions within it.

Although it clearly does not apply to me, you had better
give it a real good look over. If you plan to export to the EU,
your products must conform to the standards as applied in the
member state to which you export.

After all you are part of the European directive. You
better get with the program...

Although it is only a directive, and clearly does NOT regulate
Web design, I am not an unreasonable man. So I am willing
to offer you a deal...

You stop chanting CB voodoo and false claims, and stop trying
to sell your SplatterMax here in the UK, and I will do my best to
ensure that all future pages are manufactured using RoHS
compatible pixels and ozone-friendly CSS.

Sound reasonable to you?

Regards,
Peter.

Hey... What Happened to Frank?

"Telstar Electronics" ignored
the facts, preferring to post his unproven CB voodoo...

Griffter voodoo snipped

Ill take that standard spam message as another "guilty" plea: That
you know the claims will mislead potential customers, but you only
care about trying to sell your outdated product.

Peter.
