PRO-2042 Programmable Scanner
(200-0464)                 Guide to Scanning          Faxback Doc. # 31535

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.

During the summer months, you might be able to hear stations in the 30-50
MHz range located several hundred or even thousands of miles away.  This
is because of summer atmospheric conditions.  This type of reception is
unpredictable but often very interesting!

Ham Radio Frequencies

Ham radio operators often broadcast emergency information when other means of communication break down.

The following chart shows the voice frequencies that you can monitor.

Birdie Frequencies

Birdies are frequencies your scanner uses when it operates.  These
operating frequencies might interfere with broadcasts on the same
frequencies.  If you tune 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.  These are the most common birdies to
watch for:

NOTE:  Depending on the temperature of some of the scanner's components,
       you might hear birdies on frequencies slightly above or below the
       frequencies listed here.
