This is the command quisk that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
quisk - a Software Defined Radio (SDR)
DESCRIPTION
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.
SETUP
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.
