Sec. 22.709  Rural radiotelephone service application requirements.

    In addition to information required by subparts B and D of this 
part, applications for authorization to operate a station in the Rural 
Radiotelephone Service must contain the applicable supplementary 
information described in this section.
    (a) Interoffice stations. Applications for authority to operate a 
new interoffice station or to add transmitters or points of 
communications to an existing interoffice station must contain an 
exhibit demonstrating that the requested facilities would be used only 
for interconnecting central office stations and explaining why the use 
of alternative existing radio or wire facilities is not feasible.

    (b) Technical information required. For each transmitter in the 
Rural Radiotelephone Service, the following information is required by 
FCC Form 600 Schedule B:
    (1) Location description; city; county; state; geographical 
coordinates correct to &177;1 second, the datum used (NAD 27 or 
NAD 83), site elevation above mean sea level, proximity to adjacent 
market boundaries and international borders;
    (2) Antenna manufacturer, model number and type, antenna height to 
tip above ground level, the height of the center of radiation of the 
antenna above the average terrain, the height of the antenna center of 
radiation above the average elevation of the terrain along each of the 8 
cardinal radials, antenna gain in the maximum lobe, the beamwidth of the 
maximum lobe of the antenna, a polar plot of the horizontal gain pattern 
of the antenna, the electric field polarization of the wave emitted by 
the antenna when installed as proposed;
    (3) The center frequency of each channel requested, the maximum 
effective radiated power, the effective radiated power in each of the 
cardinal radial directions, any non-standard emission types to be used, 
including bandwidth and modulation type, the transmitter classification 
(e.g. central office), and the locations and call signs, if any, of any 
fixed points of communication.
    (c) No landline facilities. Each application for a central office 
station must contain an exhibit showing that it is impracticable to 
provide the required communication service by means of landline 
facilities.
    (d) Interference exhibit. Applications for central office, 
interoffice and relay stations must include an exhibit identifying co-
channel facilities and demonstrating, in accordance with Sec. 22.715 
that the proposed station, if authorized, would not cause interference 
to the service of those co-channel facilities. 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.
    (e) Blocking probability. Applications for authority to operate 
basic exchange telephone radio systems (BETRS) that request more than 
two channel pairs must include an exhibit containing calculations 
showing that the number of channels requested is the minimum necessary 
to achieve the required grade of service (in terms of blocking 
probability), and that there will be adequate spectrum available in the 
area to meet realistic estimates of current and future demand for 
paging, two-way mobile and rural radiotelephone services (see 
Sec. 22.719(c)). Applications for authority to operate new conventional 
rural radiotelephone systems that request more than two channel pairs 
must include a statement explaining why BETRS technology is not being 
proposed.
