GENERAL GUIDE TO SCANNING
BIRDIES
Birdies are frequencies your scanner uses when it operates.
These operating frequencies might interfere with broadcasts
on the same frequencies. If you program one of these fre¬
quencies, the scanner locks up and you hear only noise on
that frequency.
If the interference is not severe, you might be able to rotate
SQUELCH clockwise to cut out the birdie. The most common
“birdies” to watch for are listed below.

RECEPTION NOTES
Reception of the frequencies covered by your PRO-50 is
mainly “line of sight.” That means you usually won’t be able
to hear stations that are located beyond the horizon.
During the summer months, you might be able to hear sta¬
tions in the 30-50 MHz range located several hundreds or
even thousands of miles away. This is due to summer at¬
mospheric conditions. This type of reception is unpre¬
dictable, but often very interesting!
