                       TITLE 47--TELECOMMUNICATION

 

        CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION (CONTINUED)

 

PART 97_AMATEUR RADIO SERVICE--Table of Contents

 

                      Subpart D_Technical Standards

 

Sec.  97.315  Certification of external RF power amplifiers.



    (a) No more than 1 unit of 1 model of an external RF power amplifier 

capable of operation below 144 MHz may be constructed or modified during 

any calendar year by an amateur operator for use at a station without a 

grant of certification. No amplifier capable of operation below 144 MHz 

may be constructed or modified by a non-amateur operator without a grant 

of certification from the FCC.

    (b) Any external RF power amplifier or external RF power amplifier 

kit (see Sec.  2.815 of the FCC Rules), manufactured, imported or 

modified for use in a station or attached at any station must be 

certificated for use in the amateur service in accordance with subpart J 

of part 2 of the FCC Rules. This requirement does not apply if one or 

more of the following conditions are met:

    (1) The amplifier is not capable of operation on frequencies below 

144 MHz. For the purpose of this part, an amplifier will be deemed to be 

incapable of operation below 144 MHz if it is not capable of being 

easily modified to increase its amplification characteristics below 120 

MHz and either:

    (i) The mean output power of the amplifier decreases, as frequency 

decreases from 144 MHz, to a point where 0 dB or less gain is exhibited 

at 120 MHz; or

    (ii) The amplifier is not capable of amplifying signals below 120 

MHz even for brief periods without sustaining permanent damage to its 

amplification circuitry.

    (2) The amplifier was manufactured before April 28, 1978, and has 

been issued a marketing waiver by the FCC, or the amplifier was 

purchased before April 28, 1978, by an amateur operator for use at that 

amateur operator's station.

    (3) The amplifier was:

    (i) Constructed by the licensee, not from an external RF power 

amplifier kit, for use at the licensee's station; or

    (ii) Modified by the licensee for use at the licensee's station.

    (4) The amplifier is sold by an amateur operator to another amateur 

operator or to a dealer.

    (5) The amplifier is purchased in used condition by an equipment 

dealer from an amateur operator and the amplifier is further sold to 

another amateur operator for use at that operator's station.

    (c) Any external RF power amplifier appearing in the Commission's 

database as certificated for use in the amateur service may be marketed 

for use in the amateur service.
