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.
