quisk - a Software Defined Radio (SDR)

       QUISK  is  the  software that controls a receiver and transmitter.  QUISK rhymes with "brisk", and is QSK
       plus a few letters to make it easier to pronounce. QSK is a Q signal meaning full breakin CW,  and  QUISK
       has been designed for low latency CW operation.  It works fine for SSB and AM too.

       It currently runs under Linux using ALSA sound drivers or PortAudio
              and offers these capabilities:

              Quisk can control the HiQSDR.

              As  a  receiver it can use the SDR-IQ by RfSpace as a sample source.  There are several decimation
              rates available.  The screen shots below were taken using the SDR-IQ.   The  QUISK  receiver  will
              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.

              As a receiver it can use your soundcard as a sample source.  You supply a complex (I/Q)  mixer  to
              convert  radio  spectrum  to  a low IF, and send that IF to the left and right inputs of the sound
              card in your computer.  The demodulated audio goes to the same soundcard for output.

              Quisk can control SoftRock hardware for both receive and transmit.

              As a transmitter it can control my  SSB/CW exciter  and my transceiver using Ethernet.

              As a transmitter it can accept microphone  input  and  send  that  to  your  transmitter  for  SSB
              operation.   For CW, QUISK can mute the audio and substitute a side tone.  Quisk can send transmit
              data to your sound card for use with SoftRock or similar.  If you are not using SoftRock  hardware
              and  not  using  Ethernet,  then  you  can  modify  the  C code in microphone.c to connect to your
              hardware.

              If you have the SDR-IQ or the Softrock hardware, then QUISK is ready for you to use as a receiver.
              If you have other receive hardware, then you will need to change  the  file  quisk_hardware.py  to
              connect your receiver to QUISK.  For example, if you change your VFO frequency with a serial port,
              then  you  need  to  change  quisk_hardware.py  to  send  characters to the serial port.  The file
              quisk_hardware.py is written in the Python programming language, a very easy language to learn and
              use.

       Sample config files are in /usr/share/doc/quisk/quisk_conf*
              copy one, edit and save as ~/.quisk_conf.py

       For use with a Funcube Dongle see the program
              qthid in package qthid-fcd-controller.

       Some deployments of quisk will only need to use sound hardware with ALSA.  Other setups will  use  serial
       ports  (or  USB  serial  ports)  and  may need permissions set up (perhaps using udev) to allow the quisk
       program's user access to those ports. See documentation in /usr/share/doc/quisk for more information,  as
       well as configuration file examples.

       The default configuration file is ~/.quisk_conf.py

       The configuration file must be customized for the user (see the commented examples) before running quisk.
