Simultaneously multi-mode oscillator system

Claim 1

A MULTIPLE-MODE OSCILLATOR CIRCUIT COMPRISING: AN AMPLIFIER TRANSISTOR HAVING EMITTER, COLLECTOR AND CONTROL ELECTRODES; A BATTERY HAVING POSITIVE AND NEGATIVE TERMINALS; A COMMON BUS; AN AUDIO OUTPUT TRANSFORMER HAVING PRIMARY AND SECONDARY WINDINGS; A PAIR OF OUTPUT TERMINALS; A FIRST RADIO FREQUENCY COIL RESONANT WITH ITS STRAY SHUNT CAPACITANCE TO A FIRST RADIO FREQUENCY AND BEING COUPLED TO SAID COLLECTOR ELECTRODE; A SECOND RADIO FREQUENCY COIL AND SHUNT CAPACITOR RESONANT TO A SECOND RADIO FREQUENCY AND BEING COUPLED IN SERIES WITH SAID FIRST RADIO FREQUENCY COIL, SAID FIRST RADIO FREQUENCY BEING HIGHER THAN SAID SECOND RADIO FREQUENCY, AND SAID FIRST AND SECOND RADIO FREQUENCIES BEING NON-HARMONICALLY RELATED, SAID PRIMARY WINDING OF SAID AUDIO FREQUENCY OUT PUT TRANSFORMER BEING INTERCOUPLED IN SERIES BETWEEN SAID SECOND RADIO FREQUENCY COIL AND SAID NEGATIVE TERMINAL OF SAID BATTERY, AND SAID SECONDARY WINDING OF SAID AUDIO TRANSFORMER BEING COUPLED BETWEEN SAID EMITTER ELECTRODE AND SAID COMMON BUS; A DIODE AND LOAD RESISTOR COUPLED IN SERIES ACROSS THE TERMINALS OF SAID SECONDARY WINDING OF SAID AUDIO TRANSFORMER, SAID PAIR OF OUTPUT TERMINALS BEING CONNECTED RESPECTIVELY TO OPPOSITE ENDS OF SAID LOAD RESISTOR; A VOLTAGE DIVIDER RESISTOR NETWORK COUPLED BETWEEN SAID POSITIVE AND NEGATIVE TERMINALS OF SAID BATTERY WITH SAID CONTROL ELECTRODE OF SAID TRANSISTOR BEING CONNECTED TO SAID NETWORK; MEANS FOR COUPLING SAID POSITIVE TERMINAL OF SAID BATTERY TO SAID COMMON BUS AND FEEDBACK MEANS INTERCONNECTED BETWEEN SAID EMITTER ELECTRODE AND SAID SECONDARY WINDING OF SAID AUDIO TRANSFORMER AND COUPLED TO EACH OF SAID FIRST AND SECOND RADIO FREQUENCY COILS.
