1. A navigational communications transceiver for providing radio communication, bearing information and a localizer signal indicator, comprising:
- antenna connection;
a radio receiver circuit connected to said antenna connection;
an audio amlifier circuit connected to said radio receiver circuit;
a speaker connected to said audio amplifier circuit;
a RF phase lock loop circuit connected to said radio receiver circuit;
a microprocessor connected to said phase lock loop circuit and to said radio receiver circuit;
a display connected to said microprocessor;
a keyboard connected to said microprocessor;
a radio transmitter circuit connected to said microprocessor;
a microphone connected to said radio transmitter circuit;
an output amplifier circuit connected to the output of said radio transmitter circuit, the output of said output amplifier circuit being connected to said antenna connection;
a VOR phase lock loop circuit connected between said radio receiver and said microprocessor; and
a programmable memory connected to said microprocessor and containing instructions;
wherein said memory and the instructions thereof operate in conjunction with said microprocessor to calculate bearing information and to provide the bearing decoder function whereby the phase difference between two signals establishes an electronic counter period wherein pulses received are counted and converted into bearing information by said microprocessor under stored program instructions, this calculation being performed entirely within the microprocessor and memory structure.

Abstract
A hand held navigational-communications transceiver is compressed into a case having a volume of about 37 cubic inches by defining functional implementation for VOR (VHF omni-directional range) navigation. The transceiver can be selectively switched to process and display directional radial information. A microprocessor circuit provides primary circuitry information in combination with transceiver function software held in ROM (read only memory). A plurality of pre-programmed frequencies may be selected.
