   the following conditions are met:

   (1) The amplifier is constructed or modified by an amateur radio
   operator for use at an amateur station.

   (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 radio operator for use at that
   operator's station.

   (3) The amplifier is sold to an amateur radio operator or to a dealer,
   the amplifier is purchased in used condition by a dealer, or the
   amplifier is sold to an amateur radio 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.
