Sec.  2.815   External radio frequency power amplifiers.

   (a) As used in this part, an external radio frequency power amplifier is any
   device which, (1) when used in conjunction with a radio transmitter as a
   signal source is capable of amplification of that signal, and (2) is not an
   integral part of a radio transmitter as manufactured.

   (b) After April 27, 1978, no person shall manufacture, sell or lease, offer
   for sale or lease (including advertising for sale or lease), or import,
   ship, or distribute for the purpose of selling or leasing or offering for
   sale or lease, any external radio frequency power amplifier or amplifier kit
   capable of operation on any frequency or frequencies between 24 and 35 MHz.

   Note: For purposes of this part, the amplifier will be deemed incapable of
   operation between 24 and 35 MHz if:

   (1) The amplifier has no more than 6 decibels of gain between 24 and 26 MHz
   and between 28 and 35 MHz. (This gain is determined by the ratio of the
   input RF driving signal (mean power measurement) to the mean RF output power
   of the amplifier.); and

   (2) The amplifier exhibits no amplification (0 decibels of gain) between 26
   and 28 MHz.

   (c) No person shall manufacture, sell or lease, offer for sale or lease
   (including advertising for sale or lease) or import, ship or distribute for
   the purpose of selling or leasing or offering for sale or lease, any
   external radio frequency power amplifier or amplifier kit capable of
   operation on any frequency or frequencies below 144 MHz unless the amplifier
   has received a grant of type acceptance in accordance with subpart J of this
   part and subpart C of part 97 or other relevant parts of this chapter. No
   more than 10 external radio frequency power amplifiers or amplifier kits may
   be constructed for evaluation purposes in preparation for the submission of
   an application for a grant of type acceptance.

   Note: For the purposes of this part, an amplifier will be deemed incapable
   of operation below 144 MHz if the amplifier is not capable of being easily
   modified to increase its amplification characteristics below 120 MHz, and
   either:

   (1) The mean output power of the amplifier decreases, as frequency decreases
   from 144 MHz, to a point where 0 decibels or less gain is exhibited at 120
   MHz and below 120 MHz; or

   (2) The amplifier is not capable of even short periods of operation below
   120 MHz without sustaining permanent damage to its amplification circuitry.

   (d) The proscription in paragraph (b) of this section shall not apply to the
   marketing, as defined in paragraph (b) of this section, by a licensed
   amateur radio operator to another licensed amateur radio operator of an
   external radio frequency power amplifier fabricated in not more than one
   unit of the same model in a calendar year by that operator provided the
   amplifier is for the amateur operator's personal use at his licensed amateur
   radio station and the requirements of  Sec.  Sec. 97.315 and 97.317 of this chapter
   are met.

   (e) The proscription in paragraph (c) of this section shall not apply in the
   marketing, as defined in paragraph (c) of this section, by a licensed
   amateur radio operator to another licensed amateur radio operator of an
   external radio frequency power amplifier if the amplifier is for the amateur
   operator's personal use at his licensed amateur radio station and the
   requirements of  Sec.  Sec. 97.315 and 97.317 of this chapter are met.
