Sec.  22.589   One-way or two-way application requirements.

   In addition to information required by subparts B and D and  Sec. 22.529,
   applications for authorization to operate a paging transmitter on the
   channels listed in  Sec. 22.531, other than applications for a paging geographic
   area authorization, must contain the applicable supplementary information
   described in this section.

   (a) Interference exhibit. Except as provided in paragraph (b) of this
   section, an exhibit demonstrating compliance with  Sec. 22.567 with regard to
   protected transmitters is required. This exhibit must:

   (1) For UHF channels, identify each protected transmitter located within 108
   kilometers (67 miles) of the proposed transmitter in directions in which the
   distance to the interfering contour is 76.4 kilometers (47.5 miles) or less,
   and within 178 kilometers (111 miles) of the proposed transmitter in
   directions in which the distance to the interfering contour exceeds 76.4
   kilometers (47.5 miles); and identify each protected Basic Exchange
   Telephone Radio System central office transmitter in the Rural
   Radiotelephone Service within 231 kilometers (144 miles),

   (2) For VHF channels, identify each protected transmitter located within 135
   kilometers (84 miles) of the proposed transmitter in directions in which the
   distance to the interfering contour is 93.3 kilometers (58 miles) or less,
   and within 178 kilometers (111 miles) of the proposed transmitter in
   directions in which the distance to the interfering contour exceeds 93.3
   kilometers (58 miles).

   (3) For each protected transmitter identified, show the results of distance
   calculations indicating that there would be no overlap of service and
   interfering contours, or alternatively, indicate that the licensee of or
   applicant for the protected transmitter and/or the applicant, as required,
   have agreed in writing to accept any interference resulting from operation
   of the proposed transmitter.

   (b) Encompassment exhibit. An exhibit showing that the area within the
   interfering contour of the proposed transmitter would be totally encompassed
   by interfering contours of operating co-channel base transmitters controlled
   by the applicant is required for applications to operate a transmitter with
   ERP exceeding the basic power and height-power limits of  Sec. 22.565. This
   encompassment exhibit may substitute for the interference exhibit required
   in paragraph (a) of this section.
