Birdie Frequencies
Every scanner has birdie
frequencies. Birdies are signals
created inside the scanner’s
receiver. These operating
frequencies might interfere with
transmission 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 cut out the birdie. This
scanner’s birdie frequencies (in
MHz) are:
162.400 162.425 162.450
162.475 162.500 162.525
162.550
29.700 44.550 118.800
133.650 141.310 144.380
145.375 147.450 148.500
