Radio frequency signal transmitter arrangement

Claim 1

IN COMBINATION: AN AUDIO FREQUENCY OSCILLATOR; AN AUDIO FREQUENCY SWITCHING TRANSISTOR HAVING BASE, EMITTER AND COLLECTOR ELECTRODES AND SAID AUDIO FREQUENCY OSCILLATOR COUPLED BETWEEN SAID BASE AND SAID EMITTER ELECTRODES OF SAID AUDIO FREQUENCY SWITCHING TRANSISTOR FOR GENERATING AN AUDIO FREQUENCY SIGNAL BETWEEN SAID EMITTER ELECTRODE AND SAID COLLECTOR ELECTRODE OF SAID AUDIO FREQUENCY SWITCHING TRANSISTOR; AND AN RF GENERATING AND TRANSMITTING CIRCUIT COMPRISING A POWER RF OSCILLATOR TRANSISTOR HAVING BASE, EMITTER AND COLLECTOR ELECTRODES AND SAID EMITTER ELECTRODE OF SAID POWER RF OSCILLATOR TRANSISTOR CONNECTED TO SAID COLLECTOR ELECTRODE OF SAID AUDIO FREQUENCY SWITCHING TRANSISTOR FOR RECEIVING SAID AUDIO FREQUENCY SIGNAL THEREIN, AND MEANS CONNECTED BETWEEN SAID BASE ELECTRODE AND SAID CCOLLECTOR ELECTRODE OF SAID POWER RF OSCILLATOR TRANSISTOR FOR PROVIDING AN RF SIGNAL BETWEEN SAID EMITTER ELECTRODE AND SAID COLLECTOR ELECTRODE OF SAID POWER RF OSCILLATOR TRANSISTOR WHEREBY SAID AUDIO FREQUENCY SIGNAL SQUARE WAVE CURRENT AMPLITUDE MODULATES SAID RF SIGNAL, AND MEANS FOR RADIATING SAID AMPLITUDE MODULATED RF SIGNAL.
