FCC 73.610 Revised as of December 4, 2012
Goto Year:2011 |
§ 73.610 Minimum distance separations between stations.
(a) The provisions of this section relate to allotment separations and
station separations. Petitions to amend the Table of Allotments
(§ 73.606(b)) (other than those also expressly requesting amendment of
this section or § 73.609) will be dismissed and all applications for
new TV broadcast stations or for changes in the transmitter sites of
existing stations will not be accepted for filing if they fail to
comply with the requirements specified in paragraphs (b), (c) and (d)
of this section.
Note: Licensees and permittees of television broadcast stations which
were operating on April 14, 1952 pursuant to one or more separations
below those set forth in § 73.610 may continue to so operate, but in no
event may they further reduce the separations below the minimum. As the
existing separations of such stations are increased, the new
separations will become the required minimum separations until
separations are reached which comply with the requirements of § 73.610.
Thereafter, the provisions of said section shall be applicable.
(b) Minimum co-channel allotment and station separations:
Channels 2-13 Channels 14-69
I 272.7 (169.5 miles) 248.6 (154.5 miles)
II 304.9 (189.5 miles) 280.8 (174.5 miles)
III 353.2 (219.5 miles) 329.0 (204.5 miles)
(2) The minimum co-channel distance separation between a station in one
zone and a station in another zone shall be that of the zone requiring
the lower separation.
(c) Minimum allotment and station adjacent channel separations
applicable to all zones:
(1) Channels 2-13 95.7 kilometers (59.5 miles). Channels 14-69 87.7
kilometers (54.5 miles).
(2) Due to the frequency spacing which exists between Channels 4 and 5,
between Channels 6 and 7, and between Channels 13 and 14, the minimum
adjacent channel separations specified above shall not be applicable to
these pairs of channels (see § 73.603(a)).
(d) In addition to the requirements of paragraphs (a), (b) and (c) of
this section, the minimum assignment and station separations between
stations on Channels 14-69, inclusive, as set forth in Table II of
§ 73.698 must be met in either rule-making proceedings looking towards
the amendment of the Table of Assignments (§ 73.606(b)) or in licensing
proceedings. No channel listed in column (1) of Table II of § 73.698
will be assigned to any city, and no application for an authorization
to operate on such a channel will be granted, unless the distance
separations indicated at the top of columns (2) through (7), inclusive,
are met with respect to each of the channels listed in those columns
and parallel with the channel in column (1).
(e) The zone in which the transmitter of a television station is
located or proposed to be located determines the applicable rules with
respect to co-channel distance separations where the transmitter is
located in a different zone from that in which the channel to be
employed is located.
(f) The distances listed below apply only to allotments and assignments
on Channel 6 (82-88 MHz). The Commission will not accept petitions to
amend the Table of Allotments, applications for new stations, or
applications to change the channel or location of existing assignments
where the following minimum distances (between transmitter sites, in
kilometers) from any FM Channel 253 allotment or assignment are not
