Description
High-quality sound components: R2, R3 resistors, SW1 volume potentiometer, sound amplifier chip IC1 and sound coupling capacitors C9 ensure optimal sound performance and provide a superior audio experience. Precise frequency control: with the oscillation circuit of the common Q1 base modulation transformer and the adjustable CV, you can adjust the frequency between 530 and 1600 kHz. The positive feedback network R10, C19 and the high frequency bypass capacitors C18 improve frequency stability. Gain & Bias Control Q2 amplifies the high frequency amplitude signal, with C20 providing the coupling capacity and C21 acting high frequency bypass. The R11 and R12 bias resistors ensure the correct bias while B2 allows the high-frequency broadband line inductance for optimal signal output. Improve sound quality: by adjusting the sound capacitors SW3, C22 and C23, you can achieve the desired sound voltage. R15 acts negative feedback resistance and the SW2 and R14 bias resistor allow for improvement in sound quality. Harmonic Filtering The low-pass network consisting of L2, L3, C26 and C27 filters out high harmonics, resulting in a waveform very similar to a sine wave. This ensures optimal adaptation to the antenna and improves overall performance. › See more product details
