§  22.599   Assignment of 72-76 MHz channels.

   Because of the potential for interference to the reception of TV
   Channels 4 and 5 by broadcast television sets and video recorders,
   assignments of the 72-76 MHz channels are subject to the following
   conditions:

   (a) Assignments of 72-76 MHz channels for use within 129 kilometers (80
   miles) of a full service TV station transmitting on TV Channel 4 or 5
   are subject to the condition that the licensee must eliminate any
   interference caused to television reception on TV Channels 4 and 5. If
   the FCC notifies the licensee of an interference problem and the
   licensee does not resolve the problem within 90 days of such
   notification, operation of the interfering 72-76 MHz fixed station must
   be immediately discontinued.

   (b) 72-76 MHz channels may be assigned for use within 16 kilometers (10
   miles) of a full service TV station transmitting on TV Channel 4 or 5
   under a developmental authorization, pursuant to § 22.413. However, for
   use within 50 meters (164 feet) of a TV station transmitting on TV
   Channel 4 or 5, 72-76 MHZ channels may be assigned under a regular
   authorization, rather than a developmental authorization.
