Your own words belie this remark.  If you'll always be
responsible on two-way radio, then you don't need to
know anything about illegal CB linears.

(I don't think this got through, so I'll try again)

         NC/SC HAMFEST INFO MAILING LIST ANNOUNCEMENT

I have been maintaining an electronic mailing list for the last year and 
a half, and thought that there might be a few people on the net that 
would like to know about it.  I posted an announcement a year ago but
a lot of new people are on the net so I thought I would post another
announcement.

This list describes hamfests in North and South Carolina, and is updated
as needed, usually about once a month.  I have included a few hamfests
outside of the Carolinas that may be of interest.

The list has a calendar of hamfest dates and locations for the
rest of the year; and a few paragraphs about each hamfest that
will take place during the next month.   I try to include 
info about the hamfest location, whether exams are offerred,
ticket pricing, "more info" addresses, and sometimes brief remarks
about the hamfest based on my personal experience.

I developed this list to answer e-mail questions I received from
people ("Are there any hamfests in this area in the near future?"),
especially non-hams who often don't hear about the hamfests otherwise.
However, there are hams who read it as well, since I try to combine 
information from multiple sources into a simple, quickly read message.

I have been posting this information to the triangle.radio newsgroup
for the last 2 months, but I can't guarantee that I will be able to
do that after the end of the year.  I don't post it to rec.radio.amateur.misc
or other national/international groups on a regular basis
since the information is only useful to a small part of the country,
and due to the flamage that might result.

So if you need hamfest information for North and South Carolina
and would like to be put on the e-mail list,  contact me at 
cs00jmc@unccvax.uncc.edu or 3426957@mcimail.com
and I will add you to the list!

It is certainly possible to make antennas that are directional in both
horizontal and vertical polarizations.  If you make them long enough, 
then you the radiation angle will be low - however, a low angle of
radiation is what is desired for best skip reception.

Nope. If you could limit the distance that the antenna would receive

Skip signals do not necessarily have any one polarization. A signal that
is transmitted with vertical polarization may be either vertically or
horizontally polarized, depending on distance between the two stations,
which ionospheric layer the signal bounce off of as well as how many
skips the signal took getting to you.

If you have an antenna that has selectable polarization, then you could
reduce the interfering signal, but you could not eliminate it. Also, there
just might be another signal, on the other polarization that is just as
strong.  Further, if the signal happens to be half way between vertical
and horizontal polarization when it gets to you, then changing the antenna
polarization will not make any difference at all.

Looks like I committed the snafu by not adding a Followup-To: header
(I'm such a hypocrite sometimes! :-), and others are compounding the
mistake by blindly following up without noting the cross-posting.

The rec.radio.cb newsgroup was added to the path due to CB being
maligned as well as ham by the Telecom Digest moderator.

And, what gives you the right to do this, just because someone else is

more power?

I can think of very few instances where it might be proper to run illegal
power on the CB bands, and they all involve life/death emergencies. Anything
else is not responsible usage.

I am not taking you to task personally for your attitude, it is fairly
common on 11 meters. I had the same attitudes myself at one time - and

Yes, Eric. The FCC has pretty much given up on the band.  Not too surprising,
given that there are probably several million CB sets still being used on an
occasional basis. It would be an impossible task to attempt to police so many
stations.

Yes, as with audio, the effect is logarithmic.  You need a factor of 10
increase for each equal, perceptible increase of signal strength (usualy
expressed in multiples of 10 "decibels" or 10db).  So the increments
start getting pretty high pretty fast (1, 10, 100, 1000, 10000, etc.)

decibels = 10 * log power1
                ----------
                log power2

Note that this is for perceived signal strength.  You'll find on CB that
when the band is open for skip, it's open period, and any extra power is
gross overkill.  Groundwave is another matter.

Well, it's not that we're junior detective wanna-be's that watched too
much Dick Tracy in our youth.  The reasons not to have linears are
nicely summarized in the FAQ, so I won't restate them here.  And you
*WILL* interfere with something, particularly if this linear is
homebrew.  The personal radio services (ham and CB) have a subset of
honest operators who will continue their proud tradition of
self-enforcement and don't take kindly to people who cause RFI problems,
divert the FCC (which is overburdened anyway), and give the rest of us a
bad name by guilt-through-association.

Have you considered getting an amateur license?  Not only would you have
more frequencies, you could operate more power legally (and you would
have at least *SOME* technical background to use it responsibly).

Not necessarily true - depends on the competence of the person designing

I agree with all this except the part about the technical background. That
is absolutely unnecessary for getting a ham license. Now that the question
pool is public knowledge, all that is required is memorization - plus 
learning Morse code at 5 wpm if you want to work HF. No great deal, the

Here in Waterloo, there is a well-established use of channel 4 with many
local people, including myself.  We have been having problems lately with a
group of people on the other end of town that are running 1kw+ of power, and of
course have the D-104's cranked.  (yes, I mean a GROUP of people with more than
a kilowatt each!) ANyway, when skip starts rolling, they warm up their tubes
and destroy channels 1-9 on most recievers in town.  Asking them nicely to turn
down the modulation or power has proved fruitless.  People on the channel
(including myself) are getting in a "coax-clipping" kinda mood.  Any ideas

Open your local phonebook, find the phone number of the nearest Federal
Communications Commission Field Office, call them up, and tell them you want
help dealing with deliberate, illegal interference.  With the new $8,000+
fines, they might be in a mood to help out.

Of course, if you're loathe to do such a thing lest your own 100W linear gets
taken, I've no sympathy whatsoever.
