I saw a Cobra HT for CB use with 40 channels and slide on battery case
at Wal-Mart. Does anyone have any experience with this unit or know
about it? I didn't get a chance to get the model number but its the
first Cobra HT I've ever seen so I don't think they have too many models
that are HT's.

If we're going to get into the power distribution, it should be pointed out
that the "carrier gets 50% of the transmitted power" notion is strictly true
only for a single-tone (sinusoidal) modulating signal at 100% modulation.
Normal (unprocessed) voice tends to run with more power in the carrier than
in the sidebands, which is why speech processing - IF done correctly - is
a Good Thing.  This is also why SSB is such a nice idea, since it puts all
of your output power into the information-carrying sideband, and none into
a useless (from an information content point of view) carrier.

Bah. This is a common misconception. There will always be stations
that you can talk to, and not be overpowered by the high power ones.
I used to live in the same city as a person who ran a 2000 watt ham
linear and a 3 element beam on top of a "cherry tree". I could work
all the skip I wished, at the same time he was. All I had to do was
be far enough away that his signal did not desense my receiver from
overload.

Granted, there is a lot of interference. However - that 3 watt station,
which just happens to be at an ideal distance from you, is generating
just as strong a signal as that 500 watt station that is at the edge
of the ideal distance.

Over a period of about 5 years, I worked most of the states in the
US - including Alaska. I did all this from my mobile unit while driving
to and from work. I used no illegal amplifier, nor did I tune between
channels. This was done during the peak of the CB craze, when there
were still only 23 channels.

I have, many times. It got boring after a while. Working skip with
that much power is too easy.

I doubt if you will find any hams on 10 meters who use AM.  You would
probably be wasting your time.

The major advantage of SSB over AM is the almost complete elimination
of heterodynes due to the carriers being suppressed. A secondary advantage
is the reduced bandwidth - resulting in less noise pickup.

The additional 3+ db of signal strength does not gain all that much.

Greetings....

I recently bought a new car and wanted to install my CB in it.  I had the CB 
in my other car with a radio snack magnetic mount antennae.  It always seemed
to work well, and sound quality was good.  I now bought an antennae from 
(Here it comes....)  JC Whitney.  It is a small antennae, with a loaded coil,
and the cellular spiral looking thing in the middle as well.  It is about two 
feet high.  I bought this antennae because I hate the looks of normal cb 
antennae's.  Unfortunately, the transmission and receive capabilities are 
atrocious.  I don't know anything about SWR meters and such.  Has anyone ever
used an antennae like that?  It is constructed much like a cellular phone 
antennae, even goes through the glass.  Since these seem to work really well 
with cellular phones, I thought I would try it.... any ideas/suggestions?  
e-mail or post here... thanks.....

"Equal performance?"  Equal to what?  I haven't seen that many 1/4 wave
base station antennas being sold - most are 1/2 wave, 5/8 wave, or collinear
multe-wave antennas.  I have to put in another plug here for the A-99, formerly
sold as the Antron 99.  I've been through quite a few base station antennas
over the years (including homemade dipoles), and nothing's come close for
omnidirectional performance.  The A-99 cost me $45 new, and will tune down to
absolutely rock-bottom SWR.  It has no radials (unless you want it to), so it's
easy to pull it up through branches to the top of a tree.  Its white fiberglas
is, as Eric noted, not as ugly as silver-toned antennas.
It's advertised as having 9+ dBi gain, which should be about 6 dBd, which is
pretty darned good gain. I regularly make SSB contacts over 60 miles away using
the A-99.  One of the ham rags ( I think it was 73) reviewed the antenna for
10m and several other bands (with a matcher) and gave it very high marks.

There is no reason to increase a handheld from 3 watts to 5 watts.  
Remember, you must double your power in order to increase your
signal by one S-unit on the other guy's radio.   Increasing your
power by only 67% (3 watts to 5 watts) will do you little or no good.

60 watts on AM will also do you little or no good.  This will increase
your range slightly for local communication.  To "talk skip" on AM,
you will need a lot more than 60 watts.  Conditions on CB are usually
very bad, with lots of interference from other stations.  If you wish to

-> 1. Where's the best place to mount it?  (Chinmey, Edge, Gutter?) 2.
-> Is it necessary that I ground it?
-> 3. Does the cable really matter?  (Does it HAVE to be RG-58 or RG-8?)

Some people mount their antennas on the chimney, or mount the antenna on
the side of the house. I have heard a few cases of antennas mounted on a
vent pipe but I don't know how strong those pipes are and if they can
hold an 18' antenna (or whatever height you use) in a strong wind.

I wouldn't use RG-58 over 25-50 feet, which is probably less than what
you'll need for a rooftop antenna, whereas you should use RG-8 or a
cable called mini-8. RG-58 doesn't perform well in long cable runs as
many people around here have disscussed. RG-58 in a car with a short
cable won't show a noticable difference though. Be sure your antenna is
grounded properly incase of lightning.

I'm not sure when your "younger days" were.  Today, when the
band is open (i.e. when skip conditions exist), the 500W monster
stations dominate and cause tremendous interference.   There is
little or no way for a 3W AM transmitter to get through the
noise and QRM.  Theoretically, if the channel is empty, you
can certainly "work skip" with 3W AM.  Such ideal conditions
almost never exist, however.

If you don't believe me, try it.  Key up a legal power AM rig
when the band is open and see what happens.

If you want to work skip on CB, use SSB.  If you want to work
skip on AM, get a ham license and use 10 meters.

	I want to fire up my CB again. I'll be running a

	I'll be matching the antenna with a (gamma?)-matching length

	How can I minimize phone/tv RFI problems.
	
	I can buy a Lowpass filter BOOO! HISSS! or what?
	
	I've seen ARRL discuss coiling 6-8 turns of coax into a loop,
	does this work as  low-pass ? Whats apropriate to 27MHz ?

	calibrate this meter before I use it ?
	
	I tried a 50ohm resistor (5watt) but couldn't get the meter
	to adjust to 1:1.
	
	Do I need a special RF dummy-load  to get a reasonable reading ?
	
	
	If I can't get a good SWR reading should I go for a PI tuning

In the old old days, 1950s, the limit was 20 miles, but they changed
that a long time ago to 150 miles. Now that's a particularly worthless
number since it's too long for groundwave and too short for skip on
11 meters.  The reality is that you often can't tell you're working
skip until you ask the guy where he is. By then you've already broken
the rules. The FCC doesn't really care anymore, unless you're running
high power and disturbing the neighbors. Even then they don't really
care unless they get a lot of unresolved complaints or public safety
or aircraft frequencies start receiving interference. Then they care,
and right quick too.
