Quisk – Software Defined Radio transceiver

Quisk is a Software Defined Radio (SDR), software that controls a receiver and transmitter.

You supply an antenna and a complex (I/Q) mixer to convert the radio spectrum to a low IF. Then send that IF to your computer using the sound card, Ethernet or USB. The Quisk software will read the I/Q data, tune it, filter it, demodulate it, and send the audio to headphones or speakers. Quisk has a microphone input and a key input so it can operate as a complete transceiver.

Quisk has been designed for low latency CW operation. It works fine for SSB and AM too. The Quisk receiver can read the sample data, tune it, filter it, demodulate it, and send the audio to the sound card for output to external headphones or speakers. The Quisk transmitter can accept microphone input and send that to your transmitter via a soundcard or Ethernet. For CW, Quisk can mute the audio and substitute a side tone.

This is free and open source software.
