Whoa, maybe Justin would be interested in Amateur Radio, for the right reasons

finds the hobby interesting enough without the commercial side of things.

Bill is talking "real" dB; the problem here is that the calibration of S-meters
is notoriously bad, and bears little resemblance to the real change in 
received signal strentgh.  By the way, the (supposed) calibration from 1 to
9 on these meters is NOT in dB, but in "S-units", which are supposedly spaced
6 dB apart (but hardly ever really are).

Maybe. But then, they were right under the power lines. Also, the high
current lines would put out a much stronger field than any little radio
transmitter. That was my point. It that could occur, when he did not live
right at the radio antenna site, then every amateur radio operator who
ran high power would have his fluorescent lamps light up every time he
used the linear.  As I stated, the physics prohibit it happening.

I still am not convinced that you can light a fluorescent lamp by standing
near a high-tension line. I have some power mains near my house, and it
doesn't work. I have not tried to put the tubes within a couple of feet
of the mains - maybe it would work there.

I dropped out of the CB world just because of the "idiot" types.  I could give
you a dozen interesting stories on some really amazing individuals.  It seems
to me that a lot of them, as described, really are "white trash" types. 
People who don't work.  People who sit and play with echo boxes.
 
A friend of mine lived in an apartment and they decided they were going to be
"CB Good Buddies".  They ended up getting a hellacious rig that was
undoubtedly running high power.  They lashed their antenna mast to my friends'
balcony.  Then, their high power transmissions constantly was giving the
friends TVI problems - unbelievable.  They'd get on the air and use an "echo"
unit to "whistle" on the air to let their "friends" know they were on the air.
 Everything was permeated with TVI.  Their AIR CONDITIONER actually had CB
voice signals coming through it.  Eventually, these geeks were evicted, but
it's just part of the problem.
 
 During my last year of CB operation, there was a woman here in town who had
some ridiculous 5/8th wave base antenna from hell.  She had a very powerful
Browning Golden Eagle base unit as well as a linear.  She would dominate the
airwaves around here and if you attempted to talk on "her" frequencies she
would literally key up and let her dog bark through the mic until you wisely
turned your unit off and went to your HAM manuals to get on some real radio.
 
 Turns out that someone in this town later put a pin in her coax, they were so
tired of her.  The FCC wasn't doing much - the CB bands, as far as I was able
to tell were more or less unpoliced and people were running roughshod.
 
 The best incident I can think of was a guy who we were talking with late one
night.  His  signal seemed almost too smooth for CB - very nice signal quality
and my friend asked him what kind of rig he had.  He replied "Yaesu".  What
had happened was there was a HAM who was getting lots of 11 meter interference
from some CB geeks down the block with a 200 watt linear amplifier.  Plenty of
splatter and the HAM couldn't even use his equipment effectively.  So he fired
up on 11 meters, and was attempting to tell them to "knock their whistling
off".  He ended up firing up his 2KW linear and aimed his enormous Yagi at
their house and probably vaporized the morons equipment.  Vigilante justice in
the HAM bands isn't justified, but this was the first incident I had ever seen
where we ended up applauding the HAM.  Face it - many of these CB geeks are
using the veil of anonymity to act like juvenile idjits.  
 
 Sigh.  It's too bad.  I can remember a time when it was kind of fun to be on
CB.

This might actually be true. Many years ago I saw this movie about
some farmers fighting a huge power line going through their property.
They were standing under it with fluorescent bulbs in their hands and
they were lit up. If this is the case I could see a bulb being lit
from a 50Kw transmitter.

I don't disbelieve you, since my meter is labeled as an S meter.
Nevertheless, after the numbers it says dB. Mine goes from 1-30. One
to nine is spaced decently (actually the higher you go the less space
between numbers), and 10-30 is basically just one small space. 

In any case, why do they put it as dB if it is actually S units??

Use 50-ohm cable. CB antennas are generally designed or matched to produce
a 50-ohm impedence or thereabouts.

cannot afford to pay a whole lot because I am broke after paying the  
tuition for the fall semester ;(. Also is there any mail order catalog for  
cb radios? Plese let me know that too (i.e. how to get my adress listed on

Ok, what's an S meter, and what are it's units supposed to mean?
An S meter is a signal strength indicator. It's supposed to be
calibrated in *voltage* dBs. The reference value, marked S9, is
supposed to represent 50 microvolts of signal at the antenna
connector. Each S unit below S9 represents a *halving* of the
signal strength at the antenna. Note that since these are *voltage*
dBs and not *power* dBs, it takes 6 to represent a halving of the
signal. 

dBV=20*log(V1/V2) and dBP=10*log(P1/P2)

Above S9, the units are simply voltage dBs. IE 1/6th of an S unit.
That's why they're scrunched so close together. Why these units,
and why S9? At the time this system of measurement was introduced,
50 microvolts was considered a *strong* signal. We'd call it broadcast 
quality. Therefore there was no need to have measurements for stronger
signals. The S unit was chosen because it's particularly useful to
choose a halving of signal as a measurement interval due to the
peculiarities of the human auditory system. Nine steps described
the effective dynamic range of the recievers of the day.

As has been noted, no consumer equipment manufacturer bothers to
*calibrate* their "S" meters in today's equipment. However, military
and commercial equipment is still calibrated to the standard. On
consumer equipment like a CB, the "S" meter is just a relative
strength indicator.

Generally, the more metal you can get in the air, the better - for purposes

At the moment, this is even more true of satellite communication.

It is probably best to forget it. 1) without going to a lot of expense, you
cannot make the communications private - anyone who wants to listen in may
do so. 2) no long range radio communication system is reliable - with the   
possible exception of satellite communication. Satellite usage is expensive.
It is also not secure without expensive encoder/decoder setups.

Most types of radio communication require licensing. The only exception, here
in the US, is Citizen's Band Radio. It is not reliable for talking across 
town, much less long distance.

You can forget Amateur Band Radio - where most of the packet communication
traffic is. Commercial usage of the band is strictly prohibited - and enforced.

I would suggest you forget it. Either use scrambled cellular phones, or

Even if you could get a license for long range radio communication, the
most you could do is operate the equipment under the direct supervision
of a First Class Radiotelephone Licensee.
