The MXR Dyna Comp is a guitar effects pedal designed specifically for electric guitar. While it is a compressor, it wouldn’t be ideal for use in SSB transceivers for a few reasons:

  • Impedance: Guitar pedals have a much higher input impedance (typically around 1 MΩ) than what’s required for a microphone or line level signal used in SSB transceivers. This impedance mismatch could cause signal level problems and degrade the audio quality.
  • Frequency Range: The MXR Dyna Comp is designed to operate within the frequency range of electric guitars (typically 20 Hz to 20 kHz). SSB transceivers typically focus on a much narrower band of frequencies allocated for SSB communication. The compressor might not function properly outside its intended frequency range.
  • Control Parameters: The MXR Dyna Comp has controls like output and sensitivity that are meant to adjust the compression for musicality. These controls wouldn’t be directly applicable to the needs of compressing an SSB signal.

For compressing audio in SSB transceivers, a dedicated speech compressor designed for that purpose would be a more suitable choice. These compressors have the appropriate impedance, operate within the relevant frequency range, and offer controls tailored for optimizing SSB communication.
