Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created
inside the scannerʼs receiver, which may interfere with
transmissions on the same frequencies.

transmissions on the same frequencies.
If you program a frequency and hear only noise on that
frequency, it may be a birdie. If the interference is not severe,
you might be able to turn Squelch clockwise to omit the birdie.

Your scanner may have a few birdies that are so strong, rotating
the Squelch control clockwise will not solve the birdie problem.
the Squelch control clockwise will not solve the birdie problem.
If you suspect that a frequency you have programmed is being
affected by a birdie, try removing the antenna. Removing the
antenna will help determine if the interfering signal is a birdie
signal being generated inside of the scanner, or the result of an
external interference source. If the noise on a frequency is not
affected when the antenna is removed, it is almost certainly the
result of a birdie. If the noise disappears when the antenna is
affected by a birdie, try removing the antenna. Removing the
antenna will help determine if the interfering signal is a birdie
