Sec.  22.601   Existing microwave stations licensed under this part.

   Existing microwave stations (2110–2130 and 2160–2180 MHz) licensed under
   this part (pursuant to former rules) are subject to the transition rules in
    Sec. 22.602. No new microwave systems will be authorized under this part.

   (a) Coordination required. Before filing applications for authority to
   modify existing stations on these channels or major amendments to such
   applications, carriers must coordinate the planned channel usage, using the
   procedure outlined in  Sec. 22.150, with affected parties in this radio service
   and the Point-to-Point Microwave Service and the Multipoint Distribution
   Service. Affected parties are licensees and other applicants with previously
   filed pending applications whose stations could affect or be affected by the
   proposed modification of the existing station in terms of interference.

   (b) System parameters. In designing a system modification, the applicant
   must  select  sites,  equipment  and  channels that will avoid harmful
   interference to other users. All parties must cooperate fully and make
   reasonable efforts to resolve technical problems and conflicts that may
   inhibit the most effective and efficient use of the radio spectrum; however,
   a  party receiving notification is not obligated to suggest changes or
   re-design  a proposal in cases involving conflicts. The applicant must
   identify in the application all parties with which the technical proposal
   was coordinated. In the event that technical problems are not resolved or if
   an affected party does not respond to coordination efforts within 30 days
   after notification, an explanation must be contained in the application.
   Where technical conflicts are resolved by an agreement between the parties
   that  requires  special procedures to reduce the likelihood of harmful
   interference (such as the use of artificial site shielding), or would result
   in a reduction of quality or capacity of either system, the details thereof
   must be contained in the application.

   (c)  Bandwidth. Applicants must request the minimum emission bandwidth
   necessary. The FCC does not authorize bandwidths larger than 800 kHz under
   this part.
