Simple Speech Processor for Homebrew SSB Transceivers

Simple Speech Processor for Homebrew SSB Transceivers: A simple speech processor circuit for homebrew and QRP SSB transceivers, improving average talk power while maintaining clear and natural audio quality.

Good speech processing can make a dramatic difference to how a low-power SSB signal sounds on air. In homebrew and QRP SSB transceivers, transmitter audio is often clean but lacks average power, making signals sound weak during normal conversation. The compact Simple Speech Processor circuit shown here addresses that exact problem by increasing average talk power while preserving intelligibility and keeping distortion under control.
