About Scanning
Scanning is easy and fun with the UBC248CLT 50-Channel Base Scanner with AM/FM Radio.
What is Scanning?
Unlike standard AM or FM radio stations, most 2-way communications do not transmit
continuously (see Types of Communication below).
The UBC248CLT scans programmed channels at 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 departments (including rescue and paramedics)
■ Business/industrial radio
■
Utilities
■
Land transportation frequencies such as trucking firms, buses,
taxis, tow trucks, and railroads
■ Marine and amateur (ham radio) bands
