owing the oscillator to be a reliable starter. the frequency of the oscillator is determined by l1 and the 22pf trimmer capacitor and functions in the range of about 76mhz to 119mhz using the pcb i have made. tr1 = bc547 tr2 = bc547 tr3 = 2n3866 or 2n4427 the 15pf capacitor couples the top of l1 to the varicap diode which serves to add more capacitance to the tuned circuit to alter the frequency. r1 adds the supply voltage to the varicap, with a little noise decoup
