Birdies
All scanners are subject to receiving undesired signals or
birdies. Birdies are the products of internally generated
signals that make some frequencies difficult or impossible to
receive. If your scanner stops during Search Mode and no
sound is heard, it may be receiving a birdie. If the interference
is not severe, you might be able to turn the Squelch Control
counterclockwise to cut out the birdie. Or, press [SRC] to
resume searching.
If you program one of the following frequencies, you will hear
only noise on that channel.
