SDR delay solution ? (important for CW )

If Delay is important for you (example for CW) WDSP may be solution for you.

Using an Additional SDR Receiver with a Transceiver

To run an additional software-defined radio (SDR) receiver alongside a transceiver, consider these key elements to minimize latency, regardless of WDSP technology:

  • Avoid resampling in the audio track. Resampling adds delay and degrades synchronization.
  • Optimize audio buffer settings. Smaller buffers reduce latency but require sufficient processing power.
  • Choose SDR software with minimal delay. Select software designed for low-latency performance.
  • Use ASIO drivers. ASIO (Audio Stream Input/Output) bypasses system audio layers for faster processing.
  • Leverage the graphics card. Offload computations to the GPU to boost the computer’s performance with SDR software.
  • Add a delay line to the transceiver’s audio track. Adjust the delay to sync the transceiver’s audio with the additional SDR receiver.
