Ham Radio Frequencies
Ham radio operators often transmit emergency informa-
tion when other means of communication break down.
The chart below shows the frequencies the scanner re-
ceives that ham radio operators normally use:
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are sig-
nals created inside the scanner’s receiver. These oper-
ating frequencies might interfere with transmissions on
the same frequencies. If you program one of these fre-
quencies, 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 birdie frequencies (in MHz) are:
