    The base of Q2 has no DC bias voltage then its output will be rectified and very distorted.
    The collector of Q2 is floating with no load resistor to the positive supply then the base of Q3 has no DC bias voltage.
    The base of Q5 has no DC bias voltage.
    Q5 is an RF oscillator then what frequency is the output of the 18 pins IC?
