ABSTRACT:
A walkie-talkie unit having a speaker connected to a radio transceiver for normal transmitting and receiving functions, plus a selectively actuatable audio signal generator. The generator generates one of a plurality of distinct signals of different frequency in response to a hand manipulatable actuator. When the walkie-talkie is in a transmitting mode the signal is transmitted to another walkie-talkie. When the walkie-talkie is in a receiving mode the signal is amplified by the generating walkie-talkie.
