§ 73.611 Reference points and distance computations.
(a) In considering petitions to amend the Table of Allotments (§ 73.606(b)),
the following reference points shall be used by the Commission in
determining assignment separations between communities:
(1) Where transmitter sites for the pertinent channels have been authorized
in communities involved in a petition to amend the Table of Allotments,
separations between such communities shall be determined by the distance
between the coordinates of the authorized transmitter sites in the
respective communities as set forth in the Commission's authorizations
therefor.
(2) Where an authorized transmitter site is available for use as a reference
point in one community but not in the other for the pertinent channels,
separations shall be determined by the distance between the coordinates of
the transmitter site as set forth in the FCC's authorization therefor and
the coordinates of the other community as set forth in the publication of
the United States Department of the Interior entitled, Index to The National
Atlas of the United States of America. If this publication does not contain
the coordinates for said other community, the coordinates of the main post
office thereof shall be used.
(3) Where no authorized transmitter sites are available for use as reference
points in both communities for the pertinent channels, the distance between
the two communities listed in the above publication shall be used. If said
publication does not contain such distance, the separation between the two
communities shall be determined by the distance between the coordinates
thereof as set forth in the publication. Where such coordinates are not
contained in the publication, the coordinates of the main post offices of
said communities shall be used.
(4) Where the distance between the reference point in a community to which a
channel is proposed to be assigned and the reference point in another
community or communities does not meet the minimum separation requirements
of § 73.610, the channel may be assigned to such community upon a showing
that a transmitter site is available that would meet the minimum separation
requirements of § 73.610 and the minimum field strength requirements of
§ 73.685. In such cases, where a station is not authorized in the community
or communities to which measurements from the proposed channel assignment
must be made pursuant to § 73.610 a showing should also be made that the
distance between suitable transmitter sites in such other community or
communities and the proposed transmitter site for the new channel meet the
Commission's minimum spacing and coverage requirements.
(b) Station separations in licensing proceedings shall be determined by the
distance between the coordinates of the proposed transmitter site in one
community and
(1) The coordinates of an authorized transmitter site for the pertinent
channel in the other community; or, where such transmitter site is not
available for use as a reference point,
(2) The coordinates of the other community as set forth in the Index to The
National Atlas of the United States of America; or if not contained therein,
(3) The coordinates of the main post office of such other community.
(4) In addition, where there are pending applications in other communities
which, if granted, would have to be considered in determining station
separations, the coordinates of the transmitter sites proposed in such
applications must be used to determine whether the requirements with respect
to minimum separations between the proposed stations in the respective
cities have been met.
(c) In measuring assignment and station separations involving cities listed
in the Table in combination, where there is no authorized transmitter site
in any of the combination cities on the channel involved, separation
measurements shall be made from the reference point which will result in the
lowest separation.
(d) To calculate the distance between two reference points see paragraph
(c), § 73.208. However, distances shall be rounded to the nearest tenth of a
kilometer.
