A General Guide to
Scanning
Your scanner’s reception is mainly “line-of-sight.” You
usually cannot hear stations that are beyond the horizon.
GUIDE TO FREQUENCIES
National Weather Frequencies
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are sig-
nals created by the scanner’s internal circuits. These
stray frequencies might interfere with broadcasts on the
same or similar 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
SQUELCH clockwise to cut out the birdie.
This scanner’s known birdie frequencies (in MHz) are:
162.400 162.475 162.525
162.425 162.500 162.550
