Brand: PUSOKEI
  • High frequency amplification: Q2 Q1 high frequency amplitude signal amplification, C20 for coupling capacity, C21 high frequency bypass capacity, R11, R12 for the bias resistor, B2 for the high frequency broadband line inductance. B2 secondary output high frequency voltage.
  • Filter network: L2, L3, C26, C27 for the low-pass network, filter out the high harmonics so that the waveform is almost sinusoidal and fits the antenna.
  • Sound amplification: R2, R3 for access resistance to the sound source, SW1 volume potentiometer, IC1 sound amplifier chip, C9 sound coupling capacitors, C11, C12 sound bypass capacitors, R1, C8 RC filter circuit, R5, D1 power indicators.
  • HIGH FREQUENCY MODULATION: C22, C23 sound capacitors, adjust SW3 to get the right sound voltage, R15 counter-coupling resistance, SW2, R14 bias resistor, SW2 adjust, can improve the sound quality.
  • Oscillation source: Q1 consists of a common base modulation transformer oscillation circuit that produces high-frequency signals of the same amplitude. The CV can be adjusted to a frequency of 530 1600 kHz, R10, C19 for the positive feedback network, C18 for the high frequency bypass capacitors to achieve a common base and circuit, C16 power supply filtering and high frequency bypass, C17 power supply filtering; R7, R8, R9 for the pre-load resist.
