Scanner Basics
After you familiarize yourself with your scanner’s features
you can then set up your scanner.
Frequencies
A frequency is the waveband of the transmitting signal
(expressed in kHz or MHz). Your PRO-649 receives a
range of analog frequencies; the best resource for your
local frequencies is www.radioreference.com.
Also, you can use your scanner’s search functions to nd
active frequencies in your area.
Your PRO-649 scanner can receive these bands:
Frequency Range Types of Transmissions
29–54 MHz 10-Meter Ham, VHF Lo, 6-Meter Ham
108–136.9875 MHz Aircraft
137–174 MHz Military Land Mobile, 2-Meter Ham,
VHF Hi
380–512 MHz UHF Aircraft, Federal Government,
70-cm Ham, UHF Standard, UHF “T”
n Note: See “Specications” on page 30 for more
information about frequency steps.
Channels
Channels are storage areas for frequencies saved in your
scanner’s memory. Each saved frequency is assigned a
channel.
Banks
A bank is a storage area for a group of channels. Your
scanner provides 10 banks (1 to 10) that can each store
up to 20 channels, for a total of 200 channels. You can use
the banks to group and organize frequencies.
For example, you could program the frequencies used by
your local police department starting with Channel 1 (the
rst channel in bank 1) and program the re department
frequencies starting with Channel 21 (the rst channel in
bank 2).
