CB output power

is there any way to boost the power of a CB radio to more than 4 watts? my friend mentioned a "linear unit", but i dunno what exactly what that is (im guessing some sort of amp), not to mention no idea where to get one. any input? oh, and screw the FCC on this one [img]images/graemlins/tongue.gif[/img]

Re: CB output power

Here are plans you could buy to make a linear unit, and Yep not legal for CB. It says so at the bottom of the page. You will have to figure the configuration yourself.

Re: CB output power

Visit a truck stop. There's always someone selling a "linear" amp.

Basically, you're getting an amplifier that happens to amplify the 27 MHz range. The beauty of it is that it does a mighty fine job of fscking up cordless telephones and radio controlled cars.

I've got a 75watt one that I haven't installed yet. My Dad got it years ago from one of his truck drivers.

Now that all depends on the quality and attention to detail the maker puts into the amplifier. If you get a good quality amp A or AB biased (if you use SSB), don't overdrive it, it shouldn't mess with many other devices what so ever. You also have to have your connectors done properly, etc. Do *NOT* just go with some cheapie truckstop amplifier. Insist it's AB biased, that way you don't get stuck with a non-linear C biasing scheme, which is also known as a "splatter box" and will affect all sorts of electronics, sometimes even the drive-thrus...

DO everybody else who uses the radio a favor and do not buy a cheap POS splatterbox amplifier. Don't need you bleeding over onto the whole 11m band... [img]images/graemlins/crazy.gif[/img]</font>

Re: CB output power

you could get a 10 meter amateur band amp and modify it to work on 11 meters, but keep in mind that it does you no good to put out 75 watts if the guy you're trying to talk to is putting out 5 [img]images/graemlins/grin.gif[/img]

if you're not attached to your current radio, you can pick up a mobile 10 meter amateur radio that is built to put out 50 watts from the factory and it will either already go up into the CB band or you can make it go there by clipping one lead inside the radio in most cases.
