    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.
