Sec.  97.317   Standards for certification of external RF power amplifiers.

   (a) To receive a grant of certification, the amplifier must:

   (1) Satisfy the spurious emission standards of  Sec. 97.307 (d) or (e) of this
   part, as applicable, when the amplifier is operated at the lesser of 1.5 kW
   PEP  or  its full output power and when the amplifier is placed in the
   “standby” or “off” positions while connected to the transmitter.

   (2) Not be capable of amplifying the input RF power (driving signal) by more
   than 15 dB gain. Gain is defined as the ratio of the input RF power to the
   output RF power of the amplifier where both power measurements are expressed
   in peak envelope power or mean power.

   (3) Exhibit no amplification (0 dB gain) between 26 MHz and 28 MHz.

   (b) Certification shall be denied when:

   (1) The Commission determines the amplifier can be used in services other
   than the Amateur Radio Service, or

   (2) The amplifier can be easily modified to operate on frequencies between
   26 MHz and 28 MHz.
