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.
