Handheld Scanner
(200-0564) Frequency Guide Faxback Doc. # 38256
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.
