cb radio linear

i was told my linear was too much for my cb radio...i have a president washington..the linear is a varmit 1500 pep..anyone wanna trade..i was told to trade for a cobra 2000 at least .

i assume you are talking about a base station, i have set up many stations for friends of mine who are CB enthusiast any CB can be adjusted to any linear, who ever told you that don't know what they are talking about fully.
If the CB radio is over driving the linear that indicates that the radio is not tuned with to the linear. by adjusting the output of the CB radio to about 4 watts or less will solve your problem. have your tach. check it out for you. " they call me " fuzzy" OJ251 north central Texas, and I'm back out.

This is a look at the well respected and liked Cobra 2000 GTL CB Radio built between 1978 and the early 1990#39;s. PLEASE NOTE: I stated on the ...

Where can I buy a linear amplifier for a Mobil CB Radio. The radio is a Cobra 25 wx

Sec. 95.411 (CB Rule 11) May I use power amplifiers?

(a) You may not attach the following items (power amplifiers) to
your certificated CB transmitter in any way:
(1) External radio frequency (RF) power amplifiers (sometimes called
linears or linear amplifiers); or
(2) Any other devices which, when used with a radio transmitter as a
signal source, are capable of amplifying the signal.
(b) There are no exceptions to this rule and use of a power
amplifier voids your authority to operate the station.
(c) The FCC will presume you have used a linear or other external RF
power amplifier if--
(1) It is in your possession or on your premises; and
(2) There is other evidence that you have operated your CB station
with more power than allowed by CB Rule 10, Sec. 95.410.
(d) Paragraph (c) of this section does not apply if you hold a
license in another radio service which allows you to operate an external
RF power amplifier.

I have a new side band radio and tuned a set of firestik duals but dont really know how to use it besides talking to truckers on the road. What are the advantages of upper and lower side band, and how much trouble would one be in for adding a linear amplifier to their radio? What are the benifits of that? And last but not least how do I get the engine noise to go away from the radio?

Sideband is a Mode (or type) of transmission , just as AM is also another Mode.
CB's that have sideband modes will be switchable from LSB (lower sideband) and USB (upper sideband).
These modes offer greater range than normal AM.
Sideband CB's will put out 12 watts on sideband whereas AM transmissions are only 4 or 5 watts output.
Due to atmospheric conditions in the ionosphere long distances (500miles +) are possible on the CB band.

While possible on AM , the Mode is more prone to noise and fading effects , combine that with low output power makes it a poor choice for trying for long distance 'DX' contacts.

Sideband Mode is much more suitable for DX as it is less prone to distortions of the signal when it is refracted back to earth by the ionosphere. , and the extra power does help.

With the standard power of 12 watts feeding a 5/8 wave vertical I was able to make contacts easily of over 2500miles and I also made some contacts of over 5000 miles.

This is of course using the ionosphere to return the transmitted signals back to earth.
This condition is called 'Skip' , even though this is a misapplied term.

Typically without Skip , the standard transmission range of sideband Cb's with 12 watts is about 20 to 30 miles with a good antenna system.

Using an external amplifier , often called a 'Linear Amp' is illegal and is a Federal offense.
Using one and getting caught with it will incur a heavy fine and a police record that never goes away.
Performance wise, it is better to go with standard power and good antenna rather than use a poor antenna and a Linear Amp.

Electrical interference getting into the radio can be cured by installing noise suppressors on the alternator.
Older vehicles with separate regulators etc may need one there as well. , as well as distributers that use contact points.

This will cure most of your noise.

Don't forget to firmly mount the radio to the car body making sure it has a good electrical connection as well.

Run your + battery supply directly between the battery and the radio , making sure that the cable it doesn't pass nearby devices in the engine compartment (or the cabin) that makes noise (eg , alternator , electric fans , computers etc)

Make sure your antenna also is properly grounded to the vehicle body with a good solid mechanical and electrical connection.

You do not need to concern yourself with this, since external amplifiers are forbidden under FCC regulations for CB.
