Primary Usage
As a general rule, most of the radio activity is concentrated on the fol-
lowing frequencies:
VHF Band
UHF Band
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:
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.
