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.
