While I agree that most CB linears are "junk", there's plenty of junk
available in the ham bands as well. Also, there is CB equipment, real
legal radios, with receiver selectivity as good as some ham equipment.
You're painting with too broad a brush here.

Linears are illegal on the 10 meter ham band too. That's one of the things
that gets hams cranked up. The FCC banned the manufacture and sale of *all*
external amplifiers operating in the frequency range 25 MHz to 144 MHz 
because of illegal operation by CBers. That meant that hams lost the ability
to buy an amplifier that covers 10 meters or 6 meters. Of course they can
still legally *build* their own, but commercial manufacture has been banned
since 1979. Older hams still get cranked up over the fact that 11 meters
used to *be* a ham band before it was given to CB.

Almost all modern solid state transmitters are designed with ALC
(automatic level control) circuits which have two purposes:

1.  To limit the transmitter's output to below saturation.... this helps
prevent splatter and intermodulation... ALC si an essential part of a SSB
transmitter.

2.  To limit the transmitter's output if it operating into a high SWR.
A transistorized amplifier can be blown if it operated into a bad 
mismatch (high SWR).  In essence, if the transmitter does not see
a 50 ohm impedance (resistance is a component of impedance, so you can't 
use an ohmmeter to check), some of the power is reflected back into the 
transmitter and can damage transistors.  The ALC will rool back the 
drive level of the transmitter to a safe level.

These are probably being made available in the same way that the "export"
radios are freely available. I've heard that at least some of these amps
are being manufactured in Mexico (which is where a lot of the export model
radios are manufactured).

Clearly what is needed is "radio control." Just some "common-sense laws."
A 7-day waiting period and registration for everybody, and linear buy-back
programs. That'll keep the illegal equipment off the streets for sure.
Yeah, that's it.

I have a Maxon 4 watt handheld that I use in the car. Range is very difficult
to compare as there are so many variables....especially when you only own one
radio! I can tell you that range will be quite limited with the "rubber ducky"
antenna that many handhelds come with. Fortunately, most are attached with a
BNC connector and you can buy longer telescoping antennas which should help
the range quite a bit. If you're in a vehicle, then a decent whip with the
car body ground plane is probably the best for mobile range.

I've seen the Maxon unit advertised in many outdoor type catalogs (Cabella's,
Sportsman's Guide), and the J. C. Whitney catalog. Most places sell it for
$69.95 US mailorder. Radio Shack also has a variety of handhelds that range
in price from $60 US to $150 US. If you are going to use this a lot without a
car (or motorcycle w/12V cigarette receptacle), you may want to get the Ni-Cad
battery charger and 10 AA Ni-Cad batteries. Unfortunately, you'll spend near as
much on rechargable batteries and the charger as you do on the radio!

Some police departments use Q codes. Watch "Cops" on Fox and
you'll hear them. That's beside the point. Why use number or
letter codes when you can just say what you mean? Do you use
them in face-to-face conversation? (I HOPE NOT!) Do you say
"QSL" when the clerk hands you your change? When you leave 
work, do you say "I'm going QRT"? Negatory, Rubber Duck! 
Police departments probably began using them for security 
reasons. Hospitals use word codes to avoid freaking out
patients. "Code Blue" is less frightening than saying 
"Someone's dying." Neither situation pertains on Amateur
Radio voice or CB. People use number and Q codes because
they're in 'fantasy mode.' They want to be Broderick
Crawford in "Highway Patrol." Both hams and CBers who use 
them should wake up and learn a lesson from the rest of
the world. Say it in words.

A while back I purchased a pair of Uniden Pro 310E Walkie talkies.
They perform pretty well as long as you are outside, but if you are
inside a building forget it. My only complaint is that sometimes power
output seems to be somewhat limited. It only takes 8 AA which is fine
if you are using alkaline batteries, but performance is cut with
nicads.

.38db just looks really low for 1MHz given the other data points:

for that cable. Could be that attenuation behavior changes more quickly as
freq drops from 50MHz toward 1MHz than in the other ranges.
Or, maybe Rat Shack misprinted, miscalculated, or mislead. Considering the
inferiority of their coax shielding, I would suspect the third
possibility... ;->

I would expect attenuation at 50MHz to be more interesting to 27MHz
operators than attenuation at 1MHz. Also the additional data points can
give people something to impute an approximate 27MHz estimate from.

As I recall, WARC-92 made no interesting changes below 30MHz.  Since CB is
officially considered a national radio service (tell the RF that :-), I don't
think it likely that a WARC would have much effect on US CB service.  The FCC
is also unlikely to make any changes that would obsolete existing legal CB
equipment, considering the tough time they have with the existing illegal
equipment :-).

   Well, Ham equipment is built to much better tolerances to adjacent 
frequency rejection and accuracy than a CB.  
 
MORE IMPORTANT   The JUNK you see out there that CBers call "linears" are 
actually some poor quality amplifiers that care nothing for frequency 
accuracy.    PLUS, CBers typically like to crank power mikes up full, and 
it there are adjustments on their amplifiers (some do, some don't) the 
operator will likely keep all knobs maxed out.
 
     It /may/ be possible for CBers to play clean.... but here in Columbus 
OH, NONE do.   They do not buy high quality equipment... they get cheap 
worthless trash... and what's more.... they care NOTHING about their 
fellow radio players.

	Well, funny that here, on rec.radio.cb, the discussions look a lot
like they should belong in rec.radio.ham... Well, about Q/10 codes...

	Here, in good'ol France, we don't have 10 codes... But we do use Q

	51 - Hand Shakes
	73 - Friendship
	88 - Kisses
	144 - To lay down (go to bed) comes from the standard polarizarion
		of the 144MHz band.

	That was the cultural moment.
