MC3335P 80m SSB receiver electronic project

Radio Circuits

Using the MC3335P low power narrow band FM receiver can be designed a very simple 80m SSB receiver electronic project circuit using few electronic parts.
The MC3335P low power narrow band FM receiver includes dual FM conversion with Oscillators, Mixers, Quadrature Discriminator, and Meter Drive/Carrier Detect Circuitry.
The electronic project is very simple , requiring few external components and it includes a simple audio power amplifier based on a LM386 audio IC . Because the IC require a input voltage between 2 and 6 volts and the LM386 require a 9 volts DC power supply , in this circuit is used two fixed three terminal regulators. Tuning of this receiver circuit is done either with a varactor diode or variable capacitor as shown in the circuit below .
