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.
