§  95.787   RCRS additional requirements.

   Each RCRS transmitter type must be designed to satisfy all of the
   following additional requirements:

   (a) The antenna of an RCRS station transmitting in the 72 and/or 75 MHz
   frequency bands must meet the following requirements:

   (1) The antenna must be an integral part of the transmitter;

   (2) The gain of the antenna must not exceed that of a half-wave dipole;
   and

   (3) The antenna must be designed such that the electric field of the
   emitted radio waves is vertically polarized when the transmitter is
   held in the normal orientation.

   (b) Each RCRS transmitter type must be designed to transmit only on one
   or more of the channels listed in § 95.763.

   (c) For RCRS transmitter types incorporating plug-in
   frequency-determining modules that are intended to be changed by the
   operator, the modules must be submitted for certification together with
   the transmitter type. Each module must contain all of the frequency
   determining circuitry including the oscillator. Plug-in crystals are
   not considered modules and must not be accessible to the user.
