Abstract:
1. A programmable frequency scanning radio receiver comprising: a receiver for receiving radio frequency transmissions at each of a plurality of discrete frequencies; a first communication device coupled to the frequency scanning radio receiver for determining geographical location of the frequency scanning radio receiver by communication with a geographical positioning system; a memory for storing frequency data, the frequency data including plurality of frequencies corresponding to respective transmitting parties of interest located within a reception range of the geographical location of the frequency scanning radio receiver; a processing circuit coupled to the memory, the receiver, and the first communication device, accessing the memory, controlling the receiver to operate at the frequencies of the frequency data in the memory, and controlling and receiving a determination of the geographical location of the receiver by the first communication device for updating the frequency data; and a second communication device coupled to the processing circuit for communicating with a host system containing a data base of frequency allocation and geographical location information corresponding to the frequency allocations and located remotely from the receiver, supplying the geographical location of the frequency scanning radio receiver determined by the first communication device to the host system, and receiving the frequency allocations for the geographical location of the frequency scanning radio receiver from the host system, the processing circuit storing the frequency allocations for the geographical location in the memory as the frequency data.
