Primary Usage:
As a general rule, most of the radio activity is concentrated on the
following frequencies:
VHF Band:
2-Meter Amateur Band: .............................. 144.000 - 148.000 MHz
Government, police, and Fire: ...................... 153.785 - 155.980 MHz
Emergency Services: ................................ 158.730 - 159.460 MHz
Railroad: .......................................... 160.000 - 161.900 MHz
UHF Band:
.6 cm Amateur Band FM Repeaters: ................... 440.000 - 450.000 MHz
Land Mobile "Paired" Frequencies: .................. 450.000 - 470.000 MHz
Base Stations: ..................................... 451.025 - 454.950 MHz
Mobile Units: ...................................... 456.025 - 459.950 MHz
Repeater Units: .................................... 460.025 - 464.975 MHz
Control Stations: .................................. 465.025 - 469.975 MHz
NOTE:
UHF remote control stations and mobile units typically operate at 5
MHz higher than their associated base and relay repeater units.
Specified Intervals
Frequencies in different bands are accessible only at specific intervals.
For Example:
VHF, HAM, and Government: .................................. 5.0 kHz steps
All Others: ............................................... 12.5 kHz steps
Aircraft: ................................................. 25.0 kHz steps
Note:
Your scanner rounds the entered frequency to the nearest valid
frequency. For example, if you try to enter 151.473, the scanner
might accept this as 151.470.
Band Allocation
