UHF Band

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:

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.
