Sec.  22.709   Rural radiotelephone service application requirements.

   In addition to information required by Subparts B and D of this part, FCC
   Form 601 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
   601:

   (1) Location description: city; county; state; geographic coordinates
   correct to  ±1 second, the datum used (NAD83), site elevation above mean sea
   level, proximity to adjacent market boundaries and international borders;

   (2) 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;

   (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.

   (f) Antenna Information. Upon request by an applicant, licensee, or the
   Commission, a part 22 applicant or licensee of whom the request is made
   shall furnish the antenna type, model, and the name of the antenna
   manufacturer to the requesting party within ten (10) days of receiving
   written notification.
