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 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: Your scanner rounds the entered frequency to the nearest valid frequency. For example, if you try to enter 151.473, the scanner accepts this as 151.475.

Band Allocation

To help decide which frequency ranges to search, use the following listing of the typical services that use the frequencies your scanner receives. These frequen- cies are subject to change, and might vary from area to area. For a more com- plete listing, refer to the “Police Call Radio Guide Including Fire and Emergency Services,” available at your local Radio Shack store.
