A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is main-
ly “line-of-sight.” That means you usually cannot hear stations
that are beyond the horizon.
GUIDE TO FREQUENCIES
National Weather Frequencies
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals cre-
ated inside the scanner’s receiver. These operating frequen-
cies might interfere with transmissions 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. This scanner’s birdie frequencies (in MHz) are
:
To find the birdies in your individual scanner, begin by discon-
necting 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 search every
frequency range from its lowest frequency to the highest. Oc-
casionally, the searching will stop as if it had found a signal, of-
ten without any sound. That is a birdie. Make a list of all the
birdies in your scanner for future reference.
