Abstract:
A device for enabling a user to wirelessly transmit to and receive from a remote station a RF signal carried at a selected radio frequency said RF signal being messages generated by voice and including digital data, which comprises:a phone (70) for generating audio frequency data representing voice messages initiated by said user and generating audio frequency data being voice messages transmitted to said user from said remote station;a computer (16) arranged for generating and receiving digital data;modem means (14) connected to said computer (16) including a modulating circuit (68) for converting the digital data from the computer to audio frequency data and a demodulater circuit (66) for converting audio frequency data to digital data for presentation to said computer,means for generating a RF signal (76);means controlled by said user for setting frequency of said RF signal equal to said selected radio frequency;mixer (74) for modulating said RF signal with audio frequency data; from said phone and said modema manual double throw switch controllable by said user for connectingsaid mixer (74) to one of:(i) said phone when it is required to transmit to said remote station said audio frequency data generated by said phone;(ii) said modem means when it is required to transmit said audio frequency data generated by said modem to said remote station;transmitter means (62) connected to said mixer (74) for wirelessly transmitting said RF signal modulated by said audio frequency data to said remote station;receiving means (60) adapted for receiving an RF signal modulated by audio frequency data received from said remote station;means controlled by said user for adjusting said receiving means to receive said RF signal having said selected frequency;means (78) connected to said receiving means for demodulating said RF signal to audio frequency data received from said remote station;another double pole switch (64) accessible to said user having a common pole connected to said means (78) for demodulating;one output pole of said another double pole switch connected to said phone (70);another pole of said another double pole switch connected to said demodulator circuit (66) of said modem (14) whereby said switch is arranged for directing said received audio frequency data to a selected one of:(i) said phone;(ii) said modem means.
