Sec.  95.409   (CB Rule 9) What equipment may I use at my CB station?

   (a) You must use an FCC certificated CB transmitter at your CB station. You
   can identify an FCC certificated transmitter by the certification label
   placed on it by the manufacturer. You may examine a list of certificated
   equipment at any FCC Field Office or at FCC Headquarters. Use of a
   transmitter which is not FCC certificated voids your authority to operate
   the station.

   (b) You must not make, or have made, any internal modification to a
   certificated CB transmitter. (See CB Rule 25,  Sec. 95.425). Any internal
   modification to a certificated CB transmitter cancels the certification, and
   use of such a transmitter voids your authority to operate the station.
