Sec. 73.622  Digital television table of allotments.

    (a) General. The following table of allotments contains the digital 
television (DTV) channel allotments designated for the listed 
communities in the United States, its Territories, and possessions. The 
initial DTV Table of Allotments was established on April 3, 1997, to 
provide a second channel for DTV service for all eligible analog 
television broadcasters. Requests for addition of new DTV allotments, or 
requests to change the channels allotted to a community must be made in 
a petition for rule making to amend the DTV Table of Allotments. A 
request to amend the DTV table to change the channel of an allotment in 
the DTV table will be evaluated for technical acceptability using 
engineering criteria set forth in Sec. 73.623(c). A request to amend the 
DTV table to add a new allotment will be evaluated for technical 
acceptability using the geographic spacing criteria set forth in 
Sec. 73.623(d). DTV allotments designated with an asterisk are assigned 
for use by non-commercial educational broadcast stations only. Stations 
operating on DTV allotments designated with a ``c'' are required to 
comply with paragraph (g) of this section.
    (1) Petitions requesting the addition of a new allotment must 
specify a channel in the range of channels 2-51.
    (2) Petitions requesting a change in the channel of an initial 
allotment must specify a channel in the range of channels 2-59.
    (b) DTV Table of Allotments.

    (c) Availability of channels. Applications may be filed to construct 
DTV broadcast stations only on the channels designated in the DTV Table 
of Allotments set forth in paragraph (b) of this section, and only in 
the communities listed therein. Applications that fail to comply with 
this requirement, whether or not accompanied by a petition to amend the 
DTV Table, will not be accepted for filing. However, applications 
specifying channels that accord with publicly announced FCC Orders 
changing the DTV Table of Allotments will be accepted for filing even if 
such applications are tendered before the effective dates of such 
channel change. An application for authority to construct a DTV station 
on an allotment in the initial DTV table may only be filed by the 
licensee or permittee of the analog TV station with which that initial 
allotment is paired, as set forth in Appendix B of the Sixth Report and 
Order in MM Docket 87-268, FCC 97-115, adopted April 3, 1997. Copies of 
the Sixth Report and Order may be inspected during normal business hours 
at the: Federal Communications Commission, 1919 M St., NW., Dockets 
Branch (Room 239), Washington, DC 20554. This document is also available 
through the Internet on the FCC Home Page at http://www.fcc.gov. 
Applications may also be filed to implement an exchange of channel 
allotments between two or more licensees or permittees of analog TV 
stations in the same community, provided, however, that the other 
requirements of this section and of Sec. 73.623 are met with respect to 
each such application.
    (d) Reference points and distance computations. (1) The reference 
coordinates of a DTV allotment included in the initial DTV Table of 
Allotments are the coordinates of the authorized transmitting antenna 
site of the analog TV station with which that initial allotment is 
paired, as set forth in Appendix B of the Sixth Report and Order in MM 
Docket 87-268 (referenced in paragraph (c) of this section). An 
application for authority to construct or modify DTV facilities may 
specify an alternate location for the DTV transmitting antenna that is 
within 5 kilometers of the DTV allotment reference coordinates without 
consideration of electromagnetic interference to other DTV or analog TV 
broadcast stations, allotments or

[[Page 186]]

applications, provided the application complies with paragraph (f)(2) of 
this section. Location of a DTV broadcast station's transmitting antenna 
at a site more than 5 kilometers from the DTV allotment reference 
coordinates must comply with the provisions of Sec. 73.623(c). In the 
case where a DTV station has been granted authority to construct more 
than 5 kilometers from its reference coordinates pursuant to 
Sec. 73.623(c), and its authorized coverage area extends in any 
azimuthal direction beyond the DTV coverage area determined for the DTV 
allotment reference facilities, then the coordinates of such authorized 
site are to be used in addition to the coordinates of the DTV allotment 
to determine protection from new DTV allotments pursuant to 
Sec. 73.623(d) and from subsequent DTV applications filed pursuant to 
Sec. 73.623(c).
    (2) The reference coordinates of a DTV allotment not included in the 
initial DTV Table of Allotments will be designated in the FCC Order 
changing the DTV Table of Allotments and must meet the geographic 
spacing requirements of Sec. 73.623(d). An application for authority to 
construct or modify such DTV facilities must comply with the provisions 
of Sec. 73.623(c). In the case where such a DTV station has been granted 
authority to construct pursuant to Sec. 73.623(c) and its authorized 
coverage area extends in any azimuthal direction beyond the DTV coverage 
area determined for the DTV allotment reference facilities, then the 
coordinates of such authorized site are to be used in addition to the 
coordinates of the DTV allotment to determine protection from new DTV 
allotments pursuant to Sec. 73.623(d) and from subsequent DTV 
applications filed pursuant to Sec. 73.623(c).
    (3) The reference coordinates defined in paragraphs (d)(1) and 
(d)(2) of this section shall be used in considering petitions to amend 
the DTV Table of Allotments and in determining whether interference 
occurs between DTV stations and between DTV and analog TV stations.
    (4) In cases where there are pending applications for DTV stations 
in other communities which, if granted, would have to be considered in 
determining whether proposed or modified stations would meet the 
required technical criteria or separations, as defined in Sec. 73.623, 
the coordinates of the transmitter sites proposed in such applications 
must be used to determine whether those requirements have been met.
    (5) To calculate the distance between two reference points, see 
Sec. 73.208(c). However, distances shall be rounded to the nearest tenth 
of a kilometer.
    (e) DTV Service Areas. The service area of a DTV station is the 
geographic area within which the predicted F(50,90) field strength of 
the station's signal, in dB above 1 microvolt per meter (dBu), exceeds 
the following levels:

                                                                        
------------------------------------------------------------------------
                                                                   dBu  
------------------------------------------------------------------------
Channels 2-6...................................................       28
Channels 7-13..................................................       36
Channels 14-69.................................................       41
------------------------------------------------------------------------

    These are the levels at which reception of DTV service is limited by 
noise. Evaluation of field strength in determining service areas shall 
be made using the terrain dependent Longley-Rice point-to-point 
propagation model. Guidance for evaluating coverage areas using the 
Longley-Rice methodology is provided in OET Bulletin No. 69. Copies of 
OET Bulletin No. 69 may be inspected during normal business hours at 
the: Federal Communications Commission, 1919 M St., NW., Dockets Branch 
(Room 239), Washington, DC 20554. This document is also available 
through the Internet on the FCC Home Page at http://www.fcc.gov.
    (f) DTV maximum power and antenna heights. (1) The maximum effective 
radiated power (ERP) and antenna height above average terrain (HAAT) for 
an allotment included in the initial DTV Table of Allotments are set 
forth in Appendix B of the Sixth Report and Order in MM Docket 87-268 
(referenced in paragraph (c) of this section). These limits also appear 
on the construction permit and license issued for each DTV station. In 
each azimuthal direction, the reference ERP value is based on the HAAT 
of the corresponding analog TV station and achieving predicted coverage 
equal to that analog TV station's predicted Grade B contour, as defined 
in Sec. 73.683.

[[Page 187]]

    (2) An application for authority to construct or modify DTV 
facilities will not be subject to further consideration of 
electromagnetic interference to other DTV or analog TV broadcast 
stations, allotments or applications, provided that:
    (i) The proposed ERP in each azimuthal direction is equal to or less 
than the reference ERP in that direction; and
    (ii) The proposed HAAT is equal to or less than the reference HAAT; 
and
    (iii) The application complies with the location provisions in 
paragraph (d)(1) of this section.
    (3) DTV licensees and permittees may request an increase in either 
ERP in some azimuthal direction or HAAT, or both, that exceed the 
initial technical facilities specified for the allotment in Appendix B 
the Sixth Report and Order, up to the maximum permissible limits on DTV 
power and antenna height set forth in this section or up to that needed 
to provide the same geographic coverage area as the largest station 
within their market. Such requests must be accompanied by a technical 
showing that the increase complies with the technical criteria in 
Sec. 73.623(c), and thereby will not result in new interference, or 
statements agreeing to the change from any co-channel or adjacent 
channel stations that might be affected by potential new interference. 
In the case where a DTV station has been granted authority to construct 
pursuant to Sec. 73.623(c), and its authorized coverage area extends in 
any azimuthal direction beyond the DTV coverage area determined for the 
DTV allotment reference facilities, then the authorized DTV facilities 
are to be used in addition to the assumed facilities of the initial DTV 
allotment to determine protection from new DTV allotments pursuant to 
Sec. 73.623(d) and from subsequent DTV applications filed pursuant to 
Sec. 73.623(c).
    (4) A DTV station that operates on a channel 2-6 allotment created 
subsequent to the initial DTV Table will be allowed a maximum ERP of 10 
kW if its antenna HAAT is at or below 305 meters and it is located in 
Zone I or a maximum ERP of 45 kW if its antenna HAAT is at or below 305 
meters and it is located in Zone II or Zone III.
    (i) At higher HAAT levels, such DTV stations will be allowed to 
operate with lower maximum ERP levels in accordance with the following 
table and formulas:

  Maximum Allowable ERP and Antenna Height for DTV Stations in   Zones  
                    II   or   III   on   Channels 2-6                   
------------------------------------------------------------------------
                                                                   ERP  
                     Antenna HAAT (meters)                         (kW)

305............................................................       45
------------------------------------------------------------------------

    (ii) The allowable maximum ERP for intermediate values of HAAT is 
determined using linear interpolation based on the units employed in the 
table. For DTV stations located in Zone I that operate on channels 2-6 
with an HAAT that exceeds 305 meters, the allowable maximum ERP 
expressed in decibels above 1 kW (dBk) is determined using the following 
formula, with HAAT expressed in meters:

ERPmax=92.57-33.24*log10(HAAT)

    (iii) For DTV stations located in Zone II or III that operate on 
channels 2-6 with an HAAT that exceeds 610 meters, the allowable maximum 
ERP expressed in decibels above 1 kW (dBk) is determined using the 
following formula, with HAAT expressed in meters:

ERPmax=57.57-17.08*log10(HAAT)

    (5) A DTV station that operates on a channel 7-13 allotment created 
subsequent to the initial DTV Table will be allowed a maximum ERP of 30 
kW if its antenna HAAT is at or below 305 meters and it is located in 
Zone I or a maximum ERP of 160 kW if its antenna HAAT is at or below 305 
meters and it is located in Zone II or Zone III.
    (i) At higher HAAT levels, such DTV stations will be allowed to 
operate with lower maximum ERP levels in accordance with the following 
table and formulas:

    (ii) The allowable maximum ERP for intermediate values of HAAT is 
determined using linear interpolation based on the units employed in the 
table. For DTV stations located in Zone I that operate on channels 7-13 
with an HAAT that exceeds 305 meters, the allowable maximum ERP 
expressed in decibels above 1 kW (dBk) is determined using the following 
formula, with HAAT expressed in meters:

ERPmax=97.35-33.24*log10(HAAT)

    (iii) For DTV stations located in Zone II or III that operate on 
channels 7-13 with an HAAT that exceeds 610 meters, the allowable 
maximum ERP expressed in decibels above 1 kW (dBk) is determined using 
the following formula, with HAAT expressed in meters:

ERPmax=62.34-17.08*log10(HAAT)

    (6) A DTV station that operates on a channel 14-59 allotment created 
subsequent to the initial DTV Table will be allowed a maximum ERP of 
1000 kW if their antenna HAAT is at or below 365 meters.
    (i) At higher HAAT levels, such DTV stations will be allowed to 
operate with lower maximum ERP levels in accordance with the following 
table and formulas:

Maximum Allowable ERP and Antenna Height for DTV Stations on Channels 14-
                              59, All Zones

    (ii) The allowable maximum ERP for intermediate values of HAAT is 
determined using linear interpolation based on the units employed in the 
table. For DTV stations located in Zone I, II or III that operate on 
channels 14-59 with an HAAT that exceeds 610 meters, the allowable 
maximum ERP expressed in decibels above 1 kW (dBk) is determined using 
the following formula, with HAAT expressed in meters:

ERPmax=72.57-17.08*log10(HAAT)

    (g) For DTV stations using a channel allotment designated with a 
``c'' in paragraph (b) of this section, the pilot carrier frequency of 
the DTV signal must be maintained 5.082138 MHz above the visual carrier 
frequency of the analog TV broadcast station operating on the lower 
adjacent channel, located within 88 kilometers of the DTV broadcast 
station. This frequency difference must be maintained within a tolerance 
of 3 Hz.
    (h)(1) The field strength or voltage of emissions on frequencies 
outside the authorized channel of operation must be attenuated no less 
than the following amounts below the average transmitted power within 
the authorized channel. At the channel edge, emissions must be 
attenuated no less than 46 dB. More than 6 MHz from the channel edge, 
emissions must be attenuated no less than 71 dB. At any frequency 
between 0 and 6 MHz from the channel edge, emissions must be attenuated 
no less than the value determined by the following formula:

Attenuation in dB=46+[(f)2/1.44];

Where:

f=frequency difference in MHz from the edge of the channel.

    (2) This attenuation is based on a measurement bandwidth of 500 kHz. 
Other measurement bandwidths may be used as long as appropriate 
correction

[[Page 189]]

factors are applied. Emissions include sidebands, spurious emissions and 
radio frequency harmonics. Attenuation is to be measured at the output 
terminals of the transmitter (including any filters that may be 
employed). In the event of interference caused to any service, greater 
attenuation may be required.

    Note to paragraph (h): Greater attenuation may be required for 
situations where the DTV station and an adjacent channel analog TV 
station serve the same area and there are expected to be locations 
within that shared area where the analog TV station's field strength is 
less than 12 dB above the DTV station's field strength.
