Primary Usage

As a general rule, most of the radio activity is concentrated on the
following frequencies:

VHF Band

┌───────────────────────────────────┬────────────────────────────────┐
│           Activities              │         Frequencies            │
├───────────────────────────────────┼────────────────────────────────┼
│   Government, Police, and Fire    │      153.785-155.980 MHz       │
│   Emergency Services              │      158.730-159.460 MHz       │
│   Railroad                        │      160.000-161.900 MHz       │
└────────────────────────────────────────────────────────────────────┘

UHF Band

┌───────────────────────────────────┬────────────────────────────────┐
│           Activities              │         Frequencies            │
├───────────────────────────────────┼────────────────────────────────│
│   Land-Mobile Paired Frequencies  │      450.000-470.000 MHz       │

│   Base Stations                   │      451.025-454.950 MHz       │
│   Mobile Units                    │      456.025-459.950 MHz       │
│   Relay Repeater Units            │      460.025-464.975 MHz       │
│   Remote Control Stations         │      465.025-469.975 MHz       │
└────────────────────────────────────────────────────────────────────┘

NOTE:  Remote control stations and mobile units operate at 5 MHz higher
       than their associated base stations and relay repeater units.

Specified Intervals

Frequencies in different bands are accessible only at specific intervals.

For example:

┌─────────────────────────────────┬──────────────────────────────────┐
│         Band Type               │     Specified Interval           │
├─────────────────────────────────┼──────────────────────────────────│
│     VHF, HAM, and Government    │     5.0 kHz steps                │
│     All Others                  │     12.5 kHz steps               │
│     Aircraft                    │     25.0 kHz steps               │
└────────────────────────────────────────────────────────────────────┘

NOTE:  The scanner automatically rounds the entered frequency down to the
       closest valid frequency.  For example, if you try to enter a
       frequency of 151.473, the scanner accepts it as 151.470.
