Transistors Q1 and its related components comprise a tunable oscillator. The RF signal is transmitted to the transistor Q2, the modulator. The operational amplifier IC1 increases the audio signal and then applies to the base of Q2 via resistance R4. : Transistor Q1 and its related components comprise a tunable oscillator.
