1. Circuit Description Q1 become 27.145MHz crystal oscillator and provide carrier wave for Q2 modulation Q2 adjust IC ouput modulated signal to modulation andprovide buffer amplifer The output of Q2 has tie matching: network consisting of L1« C7. L4 and C9 . that limit harmonious content and effect the proper coupling ofthe antemna to the output stage. Q3and Q4 control Q1 bring 27.143MHz crystal oscillator 2. Antenna ground and power source. The antenna consists ofa 45em long telescopic chrome over brass tubing. There is no external ground comnection, the ground is only that of the printed circuit board Electric current is supplied by a 9 Volts Primary storage cell
