A GENERAL GUIDE TO SCANNING
BIRDIES
Birdies are frequencies your scanner
uses when it operates. These operat¬
ing frequencies might interfere with
broadcasts on the same frequencies.
If you program one of these frequen¬
cies, the scanner locks up and you
hear only noise on that frequency.
If the interference is not severe, you
might be able to turn SQUELCH clock¬
wise to cut out the interference. The
most common birdies to watch for are
listed below.

RECEPTION NOTES
Reception on the frequencies covered
on your scanner is mainly line-of-
sight. That means you usually won't
be able to hear stations that are lo¬
cated beyond the horizon.
During summer months, you might be
able to hear stations in the 30-50
MHz range located several hundreds
or even thousands of miles away.
This is due to summer atmospheric
conditions. This type of reception is
unpredictable, but often very interest¬
ing.
GUIDE TO THE ACTION
BANDS
With a little investigation, you can find
active frequencies in your community
to monitor exciting events. We can
give you some general pointers, and
you can take it from there. Please use
caution and common sense when you
hear an emergency call. Never go to
the scene of an emergency. It could
be very dangerous.
Find out if there is a local club that
monitors your community's frequen¬
cies. Perhaps a local electronics re¬
pair shop that works on equipment
similar to your scanner can give you
channel frequencies used by local ra¬
dio services.
