About Scanning
Scanning Options
Scanning is easy and fun with the BC244CLT 30-Channel Base Scanner. You can
scan in 2 ways:
■
Scan channels you have programmed
■
Scan pre-programmed weather channels.
What is Scanning?
Unlike standard AM or FM radio stations, most 2-way communications do not
transmit continuously (see Types of Communication below).
The BC244CLT scans programmed channels at a rate of up to 12 channels per
second until it locates an active frequency. When the scanning stops on an active
frequency, it remains on that channel as long as the transmission continues.
When the transmission ends, the scanner stays on the channel for 2 more
seconds, waiting for a responding transmission. If no responding transmission is
detected, the scanning cycle resumes until another transmission is received.
Types of Communication
You can monitor communications such as:
■
Police and fire department (including rescue and paramedics)
■
NOAA weather broadcasts (7 pre-programmed channels)
■
Business/industrial radio
■
Motion picture and press relay
■
Aircraft
■
Auto racing frequencies
■
Utilities
■
Land transportation frequencies such as trucking firms, buses,
taxis, tow trucks, and railroads
■
Marine and amateur (ham radio) bands
■
And many more in the 29-54MHz, 137-174MHz, and
406-512MHz ranges
