47 C.F.R. § 74.502
(b) The frequency band 944-952 MHz is available for assignment to aural STL and ICR stations. One or more of the following 25 kHz segments may be stacked to form a channel which may be assigned with a maximum authorized bandwidth of 300 kHz except as noted in the following Table. The channel, will be assigned by its center frequency, channel bandwidth, and emission designator. The following frequencies are the centers of individual segments. When stacking an even number of segments, the center frequency specified will deviate from the following frequencies in that it should correspond to the actual center of stacked channels. When stacking an odd number of channels, the center frequency specified will correspond to one of the following frequencies.
944.0125, 944.0375, 944.0625, 944.0875, 944.1125, 944.1375, 944.1625, 944.1875, 944.2125, 944.2375, 944.2625, 944.2875, 944.3125, 944.3375, 944.3625, 944.3875, 944.4125, 944.4375, 944.4625, 944.4875, 944.5125, 944.5375, 944.5625, 944.5875, 944.6125, 944.6375, 944.6625, 944.6875, 944.7125, 944.7375, 944.7625, 944.7875, 944.8125, 944.8375, 944.8625, 944.8875, 944.9125, 944.9375, 944.9625, 944.9875, 945.0125, 945.0375, 945.0625, 945.0875, 945.1125, 945.1375, 945.1625, 945.1875, 945.2125, 945.2375, 945.2625, 945.2875, 945.3125, 945.3375, 945.3625, 945.3875, 945.4125, 945.4375, 945.4625, 945.4875, 945.5125, 945.5375, 945.5625, 945.5875, 945.6125, 945.6375, 945.6625, 945.6875, 945.7125, 945.7375, 945.7625, 945.7875, 945.8125, 945.8375, 945.8625, 945.8875, 945.9125, 945.9375, 945.9625, 945.9875, 946.0125, 946.0375, 946.0625, 946.0875, 946.1125, 946.1375, 946.1625, 946.1875, 946.2125, 946.2375, 946.2625, 946.2875, 946.3125, 946.3375, 946.3625, 946.3875, 946.4125, 946.4375, 946.4625, 946.4875, 946.5125, 946.5375, 946.5625, 946.5875, 946.6125, 946.6375, 946.6625, 946.6875, 946.7125, 946.7375, 946.7625, 946.7875, 946.8125, 946.8375, 946.8625, 946.8875, 946.9125, 946.9375, 946.9625, 946.9875, 947.0125, 947.0375, 947.0625, 947.0875, 947.1125, 947.1375, 947.1625, 947.1875, 947.2125, 947.2375, 947.2625, 947.2875, 947.3125, 947.3375, 947.3625, 947.3875, 947.4125, 947.4375, 947.4625, 947.4875, 947.5125, 947.5375, 947.5625, 947.5875, 947.6125, 947.6375, 947.6625, 947.6875, 947.7125, 947.7375, 947.7625, 947.7875, 947.8125, 947.8375, 947.8625, 947.8875, 947.9125, 947.9375, 947.9625, 947.9875, 948.0125, 948.0375, 948.0625, 948.0875, 948.1125, 948.1375, 948.1625, 948.1875, 948.2125, 948.2375, 948.2625, 948.2875, 948.3125, 948.3375, 948.3625, 948.3875, 948.4125, 948.4375, 948.4625, 948.4875, 948.5125, 948.5375, 948.5625, 948.5875, 948.6125, 948.6375, 948.6625, 948.6875, 948.7125, 948.7375, 948.7625, 948.7875, 948.8125, 948.8375, 948.8625, 948.8875, 948.9125, 948.9375, 948.9625, 948.9875, 949.0125, 949.0375, 949.0625, 949.0875, 949.1125, 949.1375, 949.1625, 949.1875, 949.2125, 949.2375, 949.2625, 949.2875, 949.3125, 949.3375, 949.3625, 949.3875, 949.4125, 949.4375, 949.4625, 949.4875, 949.5125, 949.5375, 949.5625, 949.5875, 949.6125, 949.6375, 949.6625, 949.6875, 949.7125, 949.7375, 949.7625, 949.7875, 949.8125, 949.8375, 949.8625, 949.8875, 949.9125, 949.9375, 949.9625, 949.9875, 950.0125, 950.0375, 950.0625, 950.0875, 950.1125, 950.1375, 950.1625, 950.1875, 950.2125, 950.2375, 950.2625, 950.2875, 950.3125, 950.3375, 950.3625, 950.3875, 950.4125, 950.4375, 950.4625, 950.4875, 950.5125, 950.5375, 950.5625, 950.5875, 950.6125, 950.6375, 950.6625, 950.6875, 950.7125, 950.7375, 950.7625, 950.7875, 950.8125, 950.8375, 950.8625, 950.8875, 950.9125, 950.9375, 950.9625, 950.9875, 951.0125, 951.0375, 951.0625, 951.0875, 951.1125, 951.1375, 951.1625, 951.1875, 951.2125, 951.2375, 951.2625, 951.2875, 951.3125, 951.3375, 951.3625, 951.3875, 951.4125, 951.4375, 951.4625, 951.4875, 951.5125, 951.5375, 951.5625, 951.5875, 951.6125, 951.6375, 951.6625, 951.6875, 951.7125, 951.7375, 951.7625, 951.7875, 951.8125, 951.8375, 951.8625, 951.8875, 951.9125, 951.9375, 951.9625, 951.9875.
