§ 95.587   FRS additional requirements.

   Each FRS transmitter type must be designed to meet the following
   additional requirements.

   (a) Transmit frequency capability. FRS transmitter types must not be
   capable of transmitting on any frequency or channel other than those
   listed in § 95.563.

   (b) Antenna. The antenna of each FRS transmitter type must meet the
   following requirements.

   (1) The antenna must be a non-removable integral part of the FRS
   transmitter type.

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

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

   (c) Digital data transmissions. FRS transmitter types having the
   capability to transmit digital data must be designed to meet the
   following requirements.

   (1) FRS units may transmit digital data containing location
   information, or requesting location information from one or more other
   FRS or GMRS units, or containing a brief text message to another
   specific FRS or GMRS unit or units.

   (2) Digital data transmissions must be initiated by a manual action or
   command of the operator, except that FRS units may be designed to
   automatically respond with location data upon receiving an
   interrogation request from another FRS unit or a GMRS unit.

   (3) Digital data transmissions must not exceed one second in duration.

   (4) Digital data transmissions must not be sent more frequently than
   one digital data transmission within a thirty-second period, except
   that an FRS unit may automatically respond to more than one
   interrogation request received within a thirty-second period.

   (d) Packet mode. FRS transmitter types must not be capable of
   transmitting data in the store-and-forward packet operation mode.

   (e) Effective September 30, 2019, no person shall manufacture or import
   hand-held portable radio equipment capable of operating under this
   subpart (FRS) and other licensed or licensed-by-rule services in this
   chapter (part 15 unlicensed equipment authorizations are permitted if
   consistent with part 15 rules).
