Reception of the frequencies covered
by your scanner is mainly “line-of-
sight.” That means you usually cannot
hear stations that are beyond the hori-
zon.

Note: These three frequencies are not
pre-programmed in the weather ser-
vice bank but can be manually pro-
grammed 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 fre-
quency. If the interference is not
severe, you might be able to turn
SQUELCH
clockwise to cut out the
birdie. This scanner’s birdie frequen-
cies (in MHz) are:
To find the birdies in your individual
scanner, begin by disconnecting the
antenna and moving it away from the
scanner. Make sure that no other near-
by 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 high-
est. 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.
