A GENERAL GUIDE TO SCANNING
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.
GUIDE TO FREQUENCIES
US Weather Frequencies
Canadian Weather Frequencies
Note: These frequencies are not pre-programmed in the weather service bank
but can be manually programmed into a channel.
Ham Radio Frequencies
Ham radio operators often transmit emergency information when other means of
communication break down. The following chart shows the frequencies the scan-
ner receives that Ham radio operators normally use:
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside the
scanner’s receiver. These operating frequencies might interfere with broadcasts
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
SQUELCH clockwise to cut out the birdie.
