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

National Weather Frequencies:

162.400                 162.475                  162.525
162.425                 162.500                  162.550
162.450

Canadian Weather Frequencies:

161.650                 161.775                  163.275

NOTE:  These frequencies are not pre-programmed in the weather service bank
       but can be manually programmed into a channel.

Birdie Frequencies

Every scanner has birdie frequencies.  Birdies are signals created inside
the scanner's receiver.  These operating frequencies might interfere with
broadcasts on the same frequencies.  If you program one of these frequen-
cies, you hear only noise on that frequency.  If the interference is not
severe, you might be able to turn SQUELCH clockwise to cut out the birdie.

This scanner's birdie frequencies (in MHz) are:

41.6000                 406.2000            438.4000          489.2500

138.7000                413.2250            445.8375          496.3750
