Birdie Frequencies

Every scanner has birdie frequencies. Birdies are signals created
inside the scannerʼs receiver, which may interfere with
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.
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
