You appear very confused over the technical terms you are using. The
misleading description doesn't fool anyone that works with radio.
The only thing that will increase range is more power or a better aerial
and/or location. You will find that the oscilloscope required to correctly
set this device with each radio would be put to better use setting the radio
without it in the first place.
Why do CBers still insist on having overdeviated signals claiming that range
will be increased? It causes a lot of splattering and most other radios
with narrow filtering will simply cut the signal thinking it is "bleedover"
as you call it.
On AM your radio will still clip the signal as it will on SSB if this extra
compressor is set incorrectly.

The only thing to do would be to modify the radio completely and remove the
TX audio conditioning circuits and replace them with this board.

I would say it's not required, certainly not in a modern radio. It will
decrease performance.

I have never experienced someone claiming to run a company that only has ONE

What have you actually designed and made rather than bought as kits from
manufacturers to re-sell to the public?

Hello Rob:

Wow what a bunch of negative vibs.

You bet it will increase distance, so will a linear amplifier, and a
better and higher antenna. As for the overmodulated signals, sure I hear
all the time, even on the lower bands. Shouldn't be a biggie.

We use to put a Diwa 440 speech processor on our CB Rigs, years ago. And
they worked great on AM and SSB, way more on SSB of course. You could
cut thru the skip with the processor on, and we didn't use no
oscillioscope. But there was some honking linears out there tho.

A well designed (probably something telstar can't do) and properly
adjusted speech processor can boost the average signal some, but most
of the claims made are just hype. Most, if not all cbers will simply
crank the gain wide open because it makes the meter "swang" more so
they think they are getting a bigger signal, and I doubt they have a
clue as to what an oscilloscope is much less how to use one.

Rob, if you understood this device at all you'd know that "cranking up
the gain" as you put it... is not possible. Only the limiting point
and noise gate have adjustment. As for you comment about "swang"...
that doesn't make any sense either. Since this speech processor holds
the modulation constant at 100%... actually there is no "swang" (that
must be a technical term of yours). You're doing well so far... lol

My 2p, I mean 2c.

The job of an audio processor is to increase the 'average level' level
of audio without changing the waveform. This can be done at both audio
and RF frequencies (RF speech processors are commonly found in many
ham transceivers).

However, even in the best processors a certain level of distortion is
generated. It's down to the designer and the user to keep this to a
minimum.

Yes, a scope is handy but I doubt your typical processor user would
know what to do with one.

Hi Jay, long time no speak. I hope your antennas are selling well.

How right you are Phil. The processor I have designed has about 0.4%
THD at 1KHz. As you know... this level of distortion is undetectable
to everyone but maybe a maestro... lol

That's because he just wants to sell something. He doesn't care what

No, I don't. That's why I want to run it through the bench. The only
thing I'm sure that works is the noise gate, but I still don't see the
point since all it does is shut off the audio when you're not talking
to eliminate ambient noise. And it's that ambient noise that let's the
other guy know that you're still keyed up. A noise gate would make
your radio sound like a cheap speaker phone, or that crappy digital
voice from Comcast. Hey, here's an idea -- when you're done talking,
why not just unkey the mic?

Well... I still don't know why you would want to bench test something
that you have said doesn't work from day one. But that aside... let's
talk about the significance of the noise gate. Your understanding of
the way the noise gate works is correct. When the audio falls below a
user-defined threshold... the audio mutes. If you stop to think that
the VoiceMax has very high gain in the AGC... you realize that any low-
level background sound will be greatly amplified... up to around
+60dB. Without the noise gate... the hissing and wind noise in the
background between words would be extremely distracting. The
background noise detracts intelligibility from the voice signal. This
blocking of background noise between words helps the vocal clarity of
the transmission. It's really quite effective .. and the audio quality
is excellent. It certainly doesn't sound like a cheap speakerphone.
The speakerphone is quite different as the the person is quite a
distance from the mic in that application. This does present a big
problem... since the S/N ratio in that appliaction is very poor.
That's why speakerphones sound hollow... due to room acoustics... and
many times are choppy on transmit/receive... because of the poor S/N
ratio... and therefore very critical threshold setting. So far there
are eight pre-production units in the field right now. I haven't had
one complaint or problem. I have two installed in both my Cobra19 and
Cobra25 using the stock mic on one... and the Astatic 636L on the
other. They both work like a million bucks. I have the audio of a
power mic... without all the background noise. In my book... that's
the best of both worlds. My on-air experiences so far in the past few
months have substantiated my beliefs that the clarity is enhanced. I
came to that conclusion knowing how much less I've had to repeat
transmissions.

Bovine excrement.

An amplifier will increase the average level, but by increasing all
levels. As many references make clear (some listed below), an
amplifier does NOT change the waveform.

The perfect amplifier or audio processor, would create zero
distortion - no change to the waveform. However, the perfect
circuit does not exist so some distortion will occur in any active
circuit.
This includes circuits already in the radio.

A processor may be any circuit that carries out the process the
designer (or marketing person) has decided on. This could be as
simple as an amplifier... it is carrying out a process.

A processor which simply amplifies all signals and clips the higher
levels can produce much distortion. A well designed and adjusted
processor could produce little more distortion than a simple
amplifier.


The question is whether "Telstar" and "well designed" go together. I
would like to see an independent review from someone without
an axe to grind.

With all due respect, equine droppings.

Processor is a general term... someone or something that

For an audio or speech processor, as with any electronic

A speech or audio processor may be no more than an amplifier... it
carries out a process on the audio you put in. It may be an
amplifier with clipping, which can cause real distortion.
A well known speech processor, sold in the UK and USA (maybe
even around the world), is exactly that - amplify, clip, amplify again.

It should be noted that a simple amplifier does increase the average
level - even if by increasing all levels. What a simple amp does not
do is to alter the dynamic range of the signal.


This can be done at both audio and RF frequencies (RF speech
processors are commonly found in many ham transceivers).


The problem here is that we may see the way things are done at
the top end, where equipment costs a friggin fortune, and
assume that is the standard or the requirement.
Cheaper versions may do the absolute minimum required for
the manufacturer to be able to legally defend the product.

As an example, what would you consider a "regulated" supply to be?
Personally, I would not call something "regulated" unless it has a
way of monitoring the output and compensating for errors. However,
manufacturers have sold "regulated" supplies which are no more than
a rectifier and smoothing.


However, even in the best processors a certain level of
distortion is generated.


Any active circuits will cause some distortion, including those
already built into the radio. Perfect circuits would produce zero
distortion, but there is no such thing as the perfect circuit.


It's down to the designer and the user to keep this to a
minimum.


Not quite.
It is up to the designer to meet the balance between quality and
price set by the company. Their job could range from the minimum
to avoid legal action, through to top of the range products at top
of the range prices.

In some cases, it may even be cheaper to risk legal action than to
correct a problem or recall products.
Which of these would have been better off playing by the rules...
Cadbury (did they get fined?), Channel 5 (fined £300,000 for game
show cheating) and West Ham (fined just a tiny portion of next
season's premiership money).


A *good quality* speech processor will be designed to reduce the dynamic
range of the signal, without overdriving the next stage, while producing
as little distortion as possible.
But do the terms "CB" and "quality" go together?


Yes, a scope is handy but I doubt your typical processor user would
know what to do with one.


Except those in Sheffield... they all have 'scopes on their submarines.
(I can joke about it, I had the sense to live on a hill).

BTW, when does full production begin? I'm still waiting to buy one so
I can run it through the bench.


Bench? Is that the American word for a shredder?

lol.

He has attempted everything from turn signals to splatter boxes, and
modulators.

No market for any of it.


No market for CB.

If his business is based purely on CB, then he must be
on to a loser from the start.

Frank... I asked you this before and never got a response. Why would
you want to spend your hard-earned money on a device that you believe
doesn't work? That makes absolutely no sense. Obviously, you know it
does function as advertised. Believe me... I don't need your money. In
fact... if I were to see you ordering one... I wouldn't sell it to
you.


Really? With replies like that, you make the most gullible of people
start to doubt your honesty.

Do you think for one minute that Rushdie refused to sell his book
to Muslims? Who the hell do you think made his book a best seller
and made him rich?

If your critics offer you their money, so they can offend
themselves with your product... take it and lol all the way
to the bank.


Regards,

Peter.

That's interesting..... I've been on the air for 30 years and I don't
recall anyone having to repeat their transmissions.... except for a
few idiots with echo boxes or snipped limiters. Regardless, you still
haven't answered my question: When is it going into full production?


Well... all I can say is you must not have much "on air" time in those
30 years if you never heard anyone have to repeat their transmission.



Oh, sure, I've heard lots of people repeat their transmissions. But
very few that needed to.


And Frank... I answered your question regarding production a couple
posts ago.



No you didn't. You said you had eight pre-production units "in the
field". I asked -when-, not how many pre-production units you had "in
the field". So.... when?


Oh, and BTW, did you ever find the schematic for your amp?



I think you might have snipped that by mistake. Well?

No, it's American for "lie detector".

Peter,
You can bet Frank knows the device works if he's willing to shell out
his hard earned money for it... no matter what he says here.
I just find it comical that he blatently says one thing and then does
another. I guess he figures nobody will notice... lol
And the sad part is... they might not out here on this group!
