Channel frequency calculation
(in the following, N = channel number)
AMPS frequency allocation
System Channel Receive frequency Transmit frequency
Not Used 990 824.010 MHz 869.010 MHz
A” 991 to 1023 824.040 to 825.000 MHz 869.040 to 870.000 MHz
A 1 to 333 825.030 to 834.990 MHz 870.030 to 879.990 MHz
B 334 to 666 835.020 to 844.980 MHz 880.020 to 889.980 MHz
A’ 667 to 716 845.010 to 846.480 MHz 890.010 to 891.480 MHz
B’ 717 to 799 846.510 to 848.970 MHz 891.510 to 893.970 MHz
1. When the channel is between 1 and 799:
Receive frequency (in MHz) = 0.03N + 825.000
Transmit frequency (in MHz) = 0.03N + 870.000
2. When the channel is between 990 and 1023:
Receive frequency (in MHz) = 0.03(N - 1023) + 825.000
Transmit frequency (in MHz) = 0.03(N - 1023) + 870.000
