[Code of Federal Regulations] [Title 47, Volume 1] [Revised as of October 1, 2003] From the U.S. Government Printing Office via GPO Access [CITE: 47CFR2.815] [Page 573-574] TITLE 47--TELECOMMUNICATION CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION PART 2--FREQUENCY ALLOCATIONS AND RADIO TREATY MATTERS; GENERAL RULES AND REGULATIONS--Table of Contents Subpart I--Marketing of Radio-frequency Devices 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: [[Page 574]] (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 Secs. 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 Secs. 97.315 and 97.317 of this chapter are met.
