Important Notice This scanning radio has been manufactured so that it will not tune to the radio frequencies assigned by the FCC for cellular telephone usage. The Electronic Communications Privacy Act of 1986, as amended, makes it a federal crime to intentionally intercept cellular or cordl ess telephone transmissions or to market this radio when a[...]

Terminology What is Scanning? Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. The BC 235XLT scans programmed channels until it finds an active frequency. Scanning stops on an active frequency and remains on that channel as long as the transmission contin ues. When the transmission ends, the scannin[...]

In a trunked radio system, which contains up to 29 different frequencies, radio users are divided into groups, often called talk groups, and these talk groups are assigned specific IDs. When someone in a talk group uses their radio, a brief bust of data is broadcast before each transmission. The trunking system computer uses this data to temporaril[...]

Fea ture H ighlig hts Trunk Tracking – Follow 800 MHz trunked public safety and public service systems just as if conventional two-way communications were used. 300 Channels – Program one frequency into each channel. You must have at least one channel programmed to use the Scan mode. 12 Bands, 10 Banks – Includes 12 bands, with Aircraft and 8[...]
