Sec. 95.411  (CB Rule 11) May I use power amplifiers?

    (a) You may not attach the following items (power amplifiers) to 
your type-accepted 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.
