While he certainly can help you break a number of federal regulations,
he also offers some things which "appear" to provide a legal
performance boost.

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

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:

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:
