A GENERAL GUIDE TO
FREQUENCIES
Reception of the frequencies
covered by your scanner is mainly
“line-of-sight.” That means you
usually cannot hear stations that
are beyond the horizon.
US Weather Frequencies
(in MHz)
Ham Radio Frequencies
Ham radio operators often
transmit emergency information
when other means of
communication break down. The
chart below shows the frequencies
the scanner receives that ham
radio operators normally use.
Birdie Frequencies
Every scanner has birdie
frequencies. Birdies are signals
created inside the scanner’s
receiver. On rare occasions,
birdies can cause interference to
channels you want to listen to.
