About Scanning

Scanning

Options

Scanning is easy and fun with the UBC144XL T 16-Channel Base Scanner. You can scan in 2 ways:

. Scan channels you have programmed

. Scan pre-programmed weather channels.

	Unlike standard AM or FM radio stations, most 2-way
	communications (see "Types of Communication" below) do
	not transmit continuously. The UBC144XL T scans
	programmed channels at the rate of about 15 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.
Typesof	You can to monitor communication such as:
