Primary Usage

As a general rule, most of the radio activity is concentrated on the fol- lowing frequencies:

VHF Band

ActivitiesFrequencies

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

Repeater Units

460.025–464.975 MHz

Control Stations

465.025–469.975 MHz

Note: Remote control stations and mobile units operate at 5 MHz high- er 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

Aircraft and 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 ac- cepts this as 151.475.
