    l wish to design a voice activated FM transmitter design which transmits at 160.7 MHz. l intend to implement my design using two or three transistors that is oneor two for amplifying and the other as part of the colpitt's oscillator. the transmitter has a range of 100m hence transmitts less power.

    the transmitter must transmit only when someone speaks, the microphone, in this case an electrect is to be used as the transducer otherwise it must be in an idle state
