Have you ever stopped to wonder why they're not available to buy in stores ?
Why Radio Shack and Best Buy don't sell them, and not even Cobra makes them ?
Why one costs a fortune if you can find a guy in the bar who's willing to sell you one ?
Why you never see them advertised anywhere ?
That's right . . . selling them is illegal, because using them is illegal.
If you were to read up on it and get a ham operator's license, you'd know how to build
a high-power linear, but you wouldn't want it anymore.
You don't. Linear amplifiers are illegal for CB use. The maximum input into the final stage of a CB transmitter is 5 watts.
Linear systems are easier to understand and help you build an understanding of the workings of a system. Once you have a firm understanding of linear systems and the mathematics are understood you will be in a better position to understand more complex non-linear systems.
convert the tubes dimensions into linear measurement's using Pi and then the volumetric calculations become much more obvious. Mike Webster.
You can calculate h parameters in CE and CB configurations by the diagram that you are looking at, but if need be there are a few formulas you can use.
You cannot build a power tube amplifier without bias. At minimum, you need some kind of negative bias on the control grid, and you might need positive bias on the screen grid as well as cathode voltage on the suppressor grid.
You don't. Linear amplifiers are illegal for CB use. The maximum input into the final stage of a CB transmitter is 5 watts.
File a report to the FCC.
No! CB power amps are very unlawful, and they can interfere with legal radio communications. (Like Amateur Radio)
Transmitting over four watts on a CB radio is actually illegal, thus, using a linear amp on a CB is illegal, as well. A linear amp attached to a radio (for argument's sake, we'll assume it's on a type of radio on which the application is legal) simply amplifies the power output. The radio transmits into the amp, the amp amplifies the signal, and transmits it to the antenna.
linear
In the US at least, no, linear amps are not legal for use on CB radios. The maximum wattage permitted for AM transmission is four watts, and the maximum wattage permitted for Single Sideband is 12 watts.
No. Not only is it illegal to amplify a CB radio beyond the FCC permitted four watts, but stereo amplifiers and linear amplifiers work in very different ways.
Cobra is one of the best rated CB walkie talkies. They have a quality build, are affordable and are also easy to find. Truck stops and electronics stores will usually carry Cobras or similar CB radios.
A 'kicker' is an illegally modified linear amp for a 10 meter ham radio, reconfigured to work with the 11 meter band.
