Welcome to QUISK


Please see CHANGELOG.txt for changes to Quisk, and the detailed documentation and help file.

NOTE: A recent wxPython 3.x is required for Windows, and perhaps Linux too. Please update your wxPython. The new wxPython 4.x "Phoenix" release is new but should work.

The latest Quisk for Linux or Windows including source is:    quisk-4.1.25.tar.gz
The latest Quisk binary for Windows is:    quisk-4.1.25.win32-py2.7.msi

The previous release of Quisk for Linux or Windows including source is:    quisk-4.1.24.tar.gz
The previous release of Quisk binary for Windows is:    quisk-4.1.24.win32-py2.7.msi

The installation instructions are here.

Downloads for the Hermes Lite Project

There is no longer a special version of Quisk for Hermes Lite. Please use the latest version above. Some debug messages are turned on.


Here are two Internet groups for general Quisk support. There are other specialized groups you can find by a search.


Quisk on Windows

Quisk is developed on Linux, but Microsoft Windows is fully supported as well. Before installing Quisk, be sure to install a 32-bit version of Python 2.7 and a compatible wxPython. You must use the 32-bit version even if you have 64-bit Windows because the Quisk extension module is 32-bit. You can install Quisk with either the binary installer or the source tarball. If you use the binary installer, Quisk installs itself as a package under site-packages under Python 2.7, and adds its menu items under Start/Programs. This is useful if you have other programs that use Quisk as a package, such as a panadapter program. It is also easier, and is what most Windows users will expect. You can uninstall Quisk by using the Windows Control Panel, add/remove programs. But it will be troublesome to find Quisk files and the source files are not included. If you download the source tarball, uncompress it into its own folder and run it with a command such as "C:\python27\pythonw.exe quisk.py". All files including the special Windows files are available.

If you download and unpack the source distribution, you can put the Quisk folder anywhere you want, and you will have easy access to all files. You can run Quisk from a terminal window using python.exe and look for error messages if anything goes wrong. But you must create menu items and shortcuts yourself.

What is Quisk?

This is QUISK, a Software Defined Radio (SDR). QUISK is the software that controls my 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. QUISK is written in Python and C, and all source is included so you can change it yourself. 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. Quisk offers these capabilities:

If you have supported hardware, then QUISK is ready for you to use. 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.

I have tried to make QUISK easy to modify so it can be used for hardware other than my own. See the packages by Leigh L. Klotz, Jr. WA5ZNU on http://pypi.python.org.

To install QUISK, download it from the links above. Then read the documentation and the help.html file for further instructions. Quisk can be installed on Linux with distutils, easy_install, or you can just use the tarball. Just unpacking the tarball is best if you plan to add files or modify Quisk. The list of recent changes is in CHANGELOG.txt.

Here are some screen shots of QUISK. The usual graph and waterfall display are available. I dislike radios that look like computer programs so I designed QUISK with lots of buttons (a personality quirk of mine I guess). Hopefully QUISK looks like a radio and it is obvious how to use it. The red/yellow/blue bars at the bottom of the graph are the band plan. They mark the CW/SSB parts of the band, and show the ARRL additions. The band plan and colors can be changed in your configuration file quisk_conf.py.
