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

   In addition to information required by subparts B and D and §  22.529,
   applications for authorization to operate a paging transmitter on the
   channels listed in §  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 §  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 §  22.565. This encompassment exhibit may
   substitute for the interference exhibit required in paragraph (a) of
   this section.
