AVOIDING IMAGE FREQUENCIES
You might discover one of your regular stations on another fre-
quency that is not listed. It might be what is known as an image
frequency. For example, you might find a service that regularly
uses a frequency of 431.875 also on 474.675.
To see if it is an image, do a little math.
Note the new frequency   474.675
Double the intermediate frequency of 21.4 MHz   (42.800)
and subtract it from the new frequency   –42.800
If the answer is the regular frequency   431.875
then you...

A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is mainly
“line-of-sight.” That means you usually cannot hear stations that
are beyond the horizon.
GUIDE TO FREQUENCIES
Ham Radio Frequencies
Ham radio operators often broadcast emergency information
when other means of communication break down.
The following chart shows the voice frequencies that you can
monitor:
National Weather Frequencies
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals...

35 the scanner. Use the search function and search every frequen-
cy range from its lowest frequency to the highest. Occasionally,
the scanner will stop searching as if it had found a signal. How-
ever, the signal often is silent. That is a birdie. Make a list of all
the birdies in your scanner for future reference.
GUIDE TO THE ACTION BANDS
Typical Band Usage (MHz)
Primary Usage
As a general rule, most of the radio activity is concentrated on
the following frequencies:
VHF BandVHF Band
Low Range...

36 UHF Band
Note:
 Remote control stations and mobile units operate at 5
MHz higher than their associated base stations and relay re-
peater units.
BAND ALLOCATION
To help decide which frequency ranges to scan, use the follow-
ing listing of the typical services that use the frequencies your
scanner receives. These frequencies are subject to change, and
might vary from area to area. For a more complete listing, refer
