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.

Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside the scanner’s receiver.
These operating frequencies 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:
Will add
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 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. 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.
