Abstract

A frequency scanning radio receiver programming system includes a frequency scanning radio receiver that scans and receives transmissions on discrete radio frequencies. The frequency scanning radio receiver is automatically programmable to monitor frequencies in a geographical area where the receiver is located. A host system including data bases of frequency allocation and geographical information assembles and sends frequency data to the frequency scanning radio receiver to program the receiver to monitor local radio frequency transmissions. The frequency data also includes identification of the transmitting parties and the frequency scanning radio receiver displays identification information to a listener.
