About Scanning
Scanning Options
Scanning is easy and fun with the BC248CLT 50-Channel Base Scanner with AM/FM Radio.
You can scan in two 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 BC248CLT 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)

■

■
Auto racing frequencies
