§ 11.47   Optional use of other communications methods and systems.

   (a) Analog and digital broadcast stations may additionally transmit EAS
   messages through other communications means. For example, on a voluntary
   basis, FM stations may use subcarriers to transmit the EAS codes including
   57  kHz using the RBDS standard produced by the National Radio Systems
   Committee (NRSC) and television stations may use subsidiary communications
   services.

   (b) Other technologies and public service providers, such as low earth
   orbiting satellites, that wish to participate in the EAS may contact the
   FCC's Public Safety and Homeland Security Bureau or their State Emergency
   Communications Committee for information and guidance.
