Licensees declining relocation may continue to use their existing channel plan but must discontinue use of the 1990-2025 MHz band when they indicate to an Emerging Technologies licensee, acting pursuant to § 74.690 or § 78.40 of this chapter, that they decline to be relocated.\n(4) [Reserved]\n(b) Subject to the conditions of paragraph (a) of this section, frequency assignments will normally be made as requested, provided that the frequency selection provisions of § 74.604 have been followed and that the frequency requested will cause no interference to existing users in the area. The Commission reserves the right to assign frequencies other than those requested if, in its opinion, such action is warranted.\n(c) Fixed link stations will be authorized to operate on one channel only.\n(d) Cable Television Relay Service stations may be assigned channels in Band D between 12,700 and 13,200 MHz subject to the condition that no harmful interference is caused to TV STL and TV relay stations authorized at the time of such grants. Similarly, new TV STL and TV relay stations must not cause harmful interference to cable television relay stations authorized at the time of such grants. The use of channels between 12,700 and 13,200 MHz by TV pickup stations is subject to the condition that no harmful interference is caused to Cable Television Relay Service stations, TV STL and TV relay stations, except as provided for in § 74.602(a) Note 2. Band D channels are also shared with certain Private Operational Fixed Stations, see § 74.638.\n(e) [Reserved]\n(f) TV auxiliary stations licensed to low power TV stations and translator relay stations will be assigned on a secondary basis, i.e., subject to the condition that no harmful interference is caused to other TV auxiliary stations assigned to TV broadcast stations, or to cable television relay service stations (CARS) operating between 12,700 and 13,200 MHz. Auxiliary stations licensed to low power TV stations and translator relay stations must accept any interference caused by stations having primary use of TV auxiliary frequencies.\n(g) The frequencies listed in the tables found in the following paragraphs are available for assignment to television STL, television relay stations, and television translator relay stations. Licensees may use either a two-way link or one or both frequencies of a frequency pair for a one-way link and must coordinate proposed operations pursuant to procedures required in § 101.103(d) of this chapter. Licensees in the fixed-satellite service may require that licensees of grandfathered stations operating in the 18.3-18.58 GHz and 19.26-19.3 GHz bands cease operations in accordance with the provisions in § 101.95 of this chapter.\n(1) 2 MHz maximum authorized bandwidth channel:\nTransmit (receive) (MHz) Receive (transmit) (MHz)\n18141.0 n/a\n(2) [Reserved]\n(3) 10 MHz maximum authorized bandwidth channels:\nTable 4 to Paragraph (g)(3)\nTransmit (receive) (MHz) Receive (transmit) (MHz)\n1560 MHz Separation\n17705.0 n/a\n17715.0 n/a\n17725.0 n/a\n17735.0 n/a\n17745.0 19305.0\n17755.0 19315.0\n17765.0 19325.0\n17775.0 19335.0\n17785.0 19345.0\n17795.0 19355.0\n17805.0 19365.0\n17815.0 19375.0\n17825.0 19385.0\n17835.0 19395.0\n17845.0 19405.0\n17855.0 19415.0\n17865.0 19425.0\n17875.0 19435.0\n17885.0 19445.0\n17895.0 19455.0\n17905.0 19465.0\n17915.0 19475.0\n17925.0 19485.0\n17935.0 19495.0\n17945.0 19505.0\n17955.0 19515.0\n17965.0 19525.0\n17975.0 19535.0\n17985.0 19545.0\n17995.0 19555.0\n18005.0 19565.0\n18015.0 19575.0\n18025.0 19585.0\n18035.0 19595.0\n18045.0 19605.0\n18055.0 19615.0\n18065.0 19625.0\n18075.0 19635.0\n18085.0 19645.0\n18095.0 19655.0\n18105.0 19665.0\n18115.0 19675.0\n18125.0 19685.0\n18135.0 19695.0\n(4) 20 MHz maximum authorized bandwidth channels:\nTable 5 to Paragraph (g)(4)\nTransmit (receive) (MHz) Receive (transmit) (MHz)\n1560 MHz Separation\n17710.0 n/a\n17730.0 n/a\n17750.0 19310.0\n17770.0 19330.0\n17790.0 19350.0\n17810.0 19370.0\n17830.0 19390.0\n17850.0 19410.0\n17870.0 19430.0\n17890.0 19450.0\n17910.0 19470.0\n17930.0 19490.0\n17950.0 19510.0\n17970.0 19530.0\n17990.0 19550.0\n18010.0 19570.0\n18030.0 19590.0\n18050.0 19610.0\n18070.0 19630.0\n18090.0 19650.0\n18110.0 19670.0\n18130.0 19690.0\n(5) 40 MHz maximum authorized bandwidth channels:\nTable 6 to Paragraph (g)(5)\nTransmit (receive) (MHz) Receive (transmit) (MHz)\n1560 MHz Separation\n17720.0 n/a\n17760.0 19320.0\n17800.0 19360.0\n17840.0 19400.0\n17880.0 19440.0\n17920.0 19480.0\n17960.0 19520.0\n18000.0 19560.0\n18040.0 19600.0\n18080.0 19640.0\n18120.0 19680.0\n(6) 80 MHz maximum authorized bandwidth channels:\nTable 7 to Paragraph (g)(6)\nTransmit (receive) (MHz) Receive (transmit) (MHz)\n1560 MHz Separation\n17740.0 n/a\n17820.0 19380.0\n17900.0 19460.0\n17980.0 19540.0\n18060.0 19620.0\n(h) TV STL, TV relay stations, and TV translator relay stations may be authorized to operate fixed point-to-point service on the UHF TV channels 14-69 on a secondary basis and subject to the provisions of subpart G of this part:\n(1) Applications for authorization in accordance with this paragraph must comply with the following technical limits or be accompanied by an engineering analysis demonstrating why these limits must be exceeded:\n(i) Maximum EIRP is limited to 35 dBW;\n(ii) Transmitting antenna beamwidth is limited to 25 degrees (measured at the 3 dB points); and\n(iii) Vertical polarization is used.\n(2) These stations must not interfere with and must accept interference from current and future full-power UHF-TV stations, LPTV stations, and translator stations.
