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

US Weather Frequencies

    162.400    162.425    162.450    162.475

    162.500    162.525    162.550

Other Weather Frequencies

    161.650    161.775    162.440    163.275

Ham Radio Frequencies

Ham radio operators often transmit emergency information when other means
of communication break down.  The following chart shows the frequencies
the scanner receives that Ham radio operators normally use:

    Wavelength (meters)                                  Frequencies (MHz)

    10-Meter.................................................29.000-29.700

    6-Meter..................................................50.000-54.000

    2-Meter................................................144.000-148.000

    70-cm..................................................420.000-450.000

    33-cm..................................................902.000-928.000

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
frequencies, 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.

The birdie frequencies on this unit to watch for are:

    32.100              36.100-36.200      40.100-40.200

    42.975              44.200             48.200-48-300

    52.200              121.500            144.600-144.800

    148.600-148.800     150.150            152.600-152.800

    155.500             160.700-160.900    166.200

    171.550             400.400            429.050

    434.400             450.450            479.100

    810.150             820.650            915.400

    944.050             949.400

To find the birdies in your scanner, begin by disconnecting the antenna
and moving it away from the scanner.  Make sure that no other nearby radio
or TV sets are turned on near the scanner.  Use the search function and
scan every frequency range from its lowest frequency to the highest.
Occasionally, the searching will stop as if it had found a signal, often
without any sound.  That is a birdie.  Make a list of all the birdies in
your scanner for future reference.
