6. Section 73.613 is amended by revising paragraph b to read as follows:
73.613

Protection of Class A TV stations.

b Due to the frequency spacing which exists between TV channels 4
and 5, between channels 6 and 7, and between channels 13 and 14, firstadjacent channel protection standards shall not be applicable to these pairs of channels. Some interference protection requirements of this section only apply to stations transmitting on the UHF TV
channels 14 through 36 see 73.603a.

7. Section 73.614 is amended by revising paragraph b5 to read as follows:
73.614 Power and antenna height requirements.

HAAT = Height Above Average Terrain measured in meters.

The boundaries specified are to be used to determine the maximum possible combination of antenna height and ERPdBk. When specifying an ERPdBk less than that permitted by the lower boundary, any antenna HAAT can be used. Also, for values of antenna HAAT
greater than 2,300 meters the maximum ERP is the lower limit specified for each equation.

8. Section 73.616 is amended by revising paragraph a to read as follows:
73.616 Post-transition DTV station interference protection.

a A petition to add a new channel to the post-transition DTV Table of Allotments contained in 73.622j of this subpart will not be accepted unless it meets: The DTV-to-DTV geographic spacing requirements of 73.623d with respect to all existing DTV
allotments in the post-transition DTV
Table; the principle community coverage requirements of 73.625a;
the Class A TV and digital Class A TV
protection requirements in paragraph f of this section; the land mobile protection requirements of 73.623e;
and the FM radio protection requirement of 73.623f.

9. Section 73.622 is amended by revising paragraphs a introductory text and a1, removing and reserving paragraph b, revising paragraphs e1

evaluated for technical acceptability using the geographic spacing criteria set forth in 73.623d. DTV allotments designated with an asterisk are assigned for use by non-commercial educational broadcast stations only. Rules governing noncommercial educational TV stations are contained in 73.621. Where there is only one technically available channel available in a community, an entity that would be eligible to operate a noncommercial educational broadcast station may, prior to application, initiate a rulemaking proceeding requesting that an unoccupied or new channel in the community be changed or added as reserved only for noncommercial educational broadcasting upon demonstrating that the noncommercial educational proponent would provide a first or second noncommercial educational TV service to 2,000 or more people who constitute 10% of the population within the proposed allocations noise limited contour.
1 Petitions requesting the addition of a new allotment must specify a channel in the range of channels 236.

1 The service area of a DTV station is the geographic area within the stations noise-limited F50,90 contour where its signal strength is predicted to exceed the noise-limited service level.
The noise-limited contour is the area in which the predicted F50,90 field strength of the stations signal, in dB
above 1 microvolt per meter dBu as determined using the method in 73.625b exceeds the following levels these are the levels at which reception of DTV service is limited by noise:

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. 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 73.623c.
