I don't have the background or education to know if these things are
the CB equivalent of snake oil, or if they really work. I would
appreciate the comments of the many technically proficient members of
this newsgroup.

In particular, I'm looking at the plans for his CP beam antenna and
the Digital Speech Processor kit. I have the skills required to
construct either, but not the knowledge to know if either project is
worth the effort.

Your advice and guidance would be appreciated.

Circular polarization of a signal is caused by "Faraday rotation" as a signal
passes through the upper atmosphere, and occurs mainly with frequencies from 100
to 1000 MHz. Unless you plan on tuning in on satellites in that frequency range,
an antenna designed for circular polarization isn't going to do much good. IOW,
the term was probably adopted into CB mythology to describe a helical antenna,
which is no more efficient than any fiberglass stick antenna, and less efficient
than an unloaded whip.

Nearly all CB radio antennas are vertical, and therefore vertically polarized.
You are wasting your resources trying to make an antenna that's capable of
receiving both vertical and horizontal polarization. For lots of antenna
information, here's a good place to start:

http://www.ac6v.com/antprojects.htm

and
the Digital Speech Processor kit. I have the skills required to
construct either, but not the knowledge to know if either project is
worth the effort.


A speech processor is an excellent idea, but I have no idea if Lou's even works.
I certainly have some misgivings about 90% average modulation! But since you
have some electronic skills, check this out:

Hey Twisty, don't you realize that you are chastising your cheerleader? After
all these years in the newsgroups, and all these people telling you that your
quoting is screwed up, and you STILL can't get it right? Dumbass.

They most certainly can, especially when said inanimate object is controlled or
directed by a person with intentions that are less than honorable, anti-social,
or just plain malicious.

Research and investigation is effort that is well spent, and that is exactly
what he was doing. Do you know how bats got around in caves before they
developed their sonar? Trial and error:

...flap, flap, flap splat! ...flap, flap, flap, splat!

Kinda like how you navigate around your lies.

Thank you for the advice, and there is a L-O-T of information at that
site.

The circular polarized beam antenna idea is not unique to Lou
Franklin. I have seen the same concept promoted by Jo Gunn Antennas

"V Series (DX Antennas) - The V Antennas have a single feed line which
transmits circular polarity. This is the most effective way to talk DX
and hold the conditions the longest. For CB'er who wants to get the
most out of his skip talking, the V's will give the best performance
possible."

http://www.jogunn.com/jgwhich.htm

I had the impression that the Jo Gunn antennas were quality products
with solid design.

I understand that for those of you in the United States, CB is
restricted to ground wave communication. However, others in this
forum are able to talk skip without running afoul of our national
regulations.

Leaving aside the question of whether or not one should talk skip on
CB, Are Lou Franklin and Jo Gunn Antennas just blowing smoke, or is
there anything in their claims that CP beams are best for skip
talking?

Smoke city. It takes a helical antenna to radiate circular polarization. Those
fiberglass CB antennas are called 'helical' only because of how they are made,
not because they radiate circular polarization (which they don't). Want to see a
true helical antenna?

http://www.cc.edu/physics/radtel01.html

That's 30 inches long for 2400 MHz -- now can you imagine the size of a helical
for 27 MHz?

The Jo Gunn antenna you cited is called a V-yagi, and is just another variation
of the basic yagi design. Assuming it is mounted horizontally, it's polarity is
horizontal, not circular.

Here's a couple more links on antennas that I should have posted first:

What? A "commercial broadcast engineer" that can't look at a schematic

modulation" would be great on AM (ask a real commercial radio
engineer, Frankie; they use 'em all the time), but when the operator
isn't saying anything there'd be a rather obnoxious noise transmitted
as the circuit searches for anything to keep the modulation at 90%. As
witness the BBC some years ago, until they learned to turn down the
processing.

But why don't you know this IF you're really a commercial broadcast
engineer as you claimed?

Not when you have four high-gain, high input-Z OP-amps on the same chip, all
inverting, all DC isolated on both the inputs and outputs, and all outputs are
unloaded. IOW, any one of them could start oscillating at any time. Or, like I
said, the thing may not even work at all because it might lock up on power up.
As far as the "processing" is concerned, it's nothing more than a clipper. The
whole thing can be done much more easily with a few discretes, and I would
certainly have much more confidence in the circuit.

"90% average
modulation" would be great on AM (ask a real commercial radio
engineer, Frankie; they use 'em all the time),


Considering that the circuit is nothing more than a preamp and clipper, I have
no idea where he gets the idea that it will achieve 90% average modulation. And
in case you missed class, any form of compression and/or clipping is a form of
distortion; i.e, more compression equals more distortion. Years ago, some AM
broadcast stations would crank up the compression to the point where the sound
quality was offensive, but that's rarely done anymore.

but when the operator

You are professing your ignorance yet again -- noise gates have been around
almost as long as compression. And for your information, compressors and gates
are considered ancient technology in broadcasting these days, because with the
newer digital audio processors you can tailor your response curve to just about
shape you want in less than a minute via software.

But why don't you know this IF you're really a commercial broadcast
engineer as you claimed?

The Jo Gunn antenna you cited is called a V-yagi, and is just another variation

horizontal, not circular.


If it looks too good to be true, it probably is.

When one of you has a time machine, let me know.
I was under the impression that Avanti was no more.
:~)

Not when you have four high-gain, high input-Z OP-amps on the same chip,
all inverting, all DC isolated on both the inputs and outputs, and all

outputs
are unloaded.



Digital speech processor?
I have details of his "DSP" - Dynamic Speech Processor, which makes claims
about a 90% average... so seems to be what is being referring to above.

Looking at the diagram, the first amp is a buffer stage, the second has a
gain of about 45 and the third a gain of about 21. From his figures for a
standard mic output, a loud whistle should produce about 6 volts into the
clipper... which is down to 500mV from the clipper into the output amp.


IOW, any one of them could start oscillating at any time.


I assume that you do not have a copy of Lou's guide to the DSP...

quote
you may get self oscillation (squealing) due to the overall high gain of the
combined DSP, power mike (if used), and radio circuits
/quote

And...

quote
The squeal problem is very common in newer Uniden SSB rigs
/quote

His "cop-out" is that with "correct adjustment", this should not happen.
But, he is putting this adjustment in the hands of people who he has said
cannot even solder correctly. And how can anyone adjust it correctly with,
as he suggests, an SWR/power meter or someone listening to your signal?


Or, like I said, the thing may not even work at
all because it might lock up on power up.



More likely, it will fail due to poor building of the circuit.
I had someone ask me to fit one for him, which he supplied as supplied by
the shop, ready made. There were all kinds of problems, including the
screened wires not being correctly connected - they were shorted between
screen and inner wire.

Also, the version I have the details for had the LM324 fitted in place of
the LM3900. It should be noted that the LM324 is a "domestic" spec chip...
and may fail in temperatures below Zero or above +70° centigrade.
The LM2902 (-40° to +85°) or LM124 (-55 to +125°) are better.


"90% average
modulation" would be great on AM (ask a real commercial radio
engineer, Frankie; they use 'em all the time),


Considering that the circuit is nothing more than a preamp and clipper, I
have no idea where he gets the idea that it will achieve 90% average
modulation.


Does he claim that *the DSP* will manage that magical 90%, or just that the
figure is possible?

quote
With correct speech processing, it is possible to increase the average
modulation to about 90%!
/quote

Unless someone has seen a statement claiming that his product does that
"90%", or that the "90%" can be done without unacceptable distortion or
harmonic content... then it is nothing but sales bumf- careful wording.
Also, it says, "about 90%".

However, here is another of quote from Lou:
quote
Up to 15dB of clipping is quite acceptable to the ear
/quote

The average peak to average ratio figure for the human voice is 14dB,
although some people may be higher or lower. The 90% quoted may
be for some people with a lower than average ratio.
Even then, to get such a high average, without an unacceptable level of
distortion, would be pretty tight... and certainly not possible without
using proper test equipment to adjust the device exactly.


in case you missed class, any form of compression and/or
clipping is a form of
distortion; i.e, more compression equals more distortion.


Certainly with clipping, but how about a VOGAD?
If it is set to reasonable attack and decay times, there should be no
problem. However, the time delay means that it would not work the same as
clipping.


Years ago, some AM broadcast stations
would crank up the compression to the point where the sound
quality was offensive, but that's rarely done anymore.


In the UK, Radio1 manages to create "offensive" audio without adding
distortion... they just play crap "music".
;~)

but when the operator isn't saying anything
there'd be a rather obnoxious noise transmitted as the
circuit searches for anything to keep the modulation at 90%. As
witness the BBC some years ago, until they learned to turn
down the processing.



The "searching for noise" will probably be associated with something
more complicated than the simple amp and clipper used in the
DSP... possibly a combination of VOGAD and clipping.
