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 SQ clockwise to omit the birdie.
To find the birdies in your 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 TUNE
function and scan 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. This is a birdie. Make a list of all the
birdies in your scanner for future reference.
Care
Keep the scanner dry; if it gets wet, wipe it dry immediately. Use and store the scanner only in normal
temperature environments. Handle the scanner carefully; do not drop it. Keep the scanner away from dust
and dirt, and wipe it with a damp cloth occasionally to keep it looking new.
Modifying or tampering with the scanner’s internal components can cause a malfunction and might
invalidate its warranty and void your FCC authorization to operate it.
The radio design of the tuning, control and filtering circuitry on the receiver is controlled by the serial data
from the firmware code in the microprocessor, which is built-in by the microprocessor manufacture as a part
of the internal design of the processor.
Since the processor information is inaccessible to the user, if someone attempt modifying circuitry without
