Block Diagram of 7 MHz SSB Transceiver for Hams

The microphone amplifier / modulator is build around LM324 which is a quad op amplifier provides enough quality amplification to voice picked up by the condenser microphone.

First and Second Mixer's are build using popular Double balanced modulator IC MC1496.

The AF Amplifier circuit used OP amplifier LM741 as pre amplifier and LM386 as power amplifier.

Most of the signal switching is done though Diodes. Relays are used to switch veriable frequency oscillator and beat frequency oscillator.
