CB Radio operators normally transmit double sideband AM on the first 23 channels. On channels above Channel 23, upper sideband or lower sideband equipment may be used. Four watts of carrier power is allowed for output on AM, and 12 watts of peak envelope power is the maximum power output on SSB. You may only use a type-accepted CB Radio transmitter. Any internal modification to a type-accepted CB Radio transmitter cancels the type acceptance, and use of such a transmitter voids your authority to operate the station. The same type regulation applies to power amplifiers. Power amplifiers are specifically disallowed for use with a CB Radio.
If you want to sound like you have an amp and not spend the money, just turn up the mic gain and yell real loud into the mic. You get the same effects of an amp for no money. Lots of splatter between channels and over modulated voice no one can understand. see, just like an amp. Heck add some echo, that will make the signal go further also :sombrero:
