A GENERAL GUIDE TO SCANNING
BIRDIES
Birdies are the products of internally generated signals that
make some frequencies difficult or impossible to receive. If
you program one of these frequencies, you might hear only
noise on the channel.
If the interference is not severe, you might be able to turn
SQUELCH clockwise 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 iine-of-sight. That means you usually cannot hear
stations that are located 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 type of reception is unpredict¬
able, but often very interesting. One very useful service is
the National Oceanic Atmospheric Administration (NOAA).
Weather Radio’s continuous weather broadcasts. These
broadcasts contain weather forecasts and data for the area
around the station, plus bulletins on any threatening weather
conditions. These stations use three frequencies— 162.40,
162.475, and 162.55 MHz. In most areas of the country, you
can receive one or more of these frequencies.
GUIDE TO THE ACTION BANDS
With the right frequencies programmed into your scanner,
you can monitor exciting events. With a little investigation,
you can find active frequencies in your community. We can
give you some general pointers, and you can take it from
there. Please use caution and common sense when you
