Quisk on Windows

Quisk now runs on Windows XP and Windows 7.  The new Windows Quisk installs easily from a quisk.msi installer file, and adds its menu items under Start/Programs.  You must install a 32-bit version of Python 2.7 and wxPython before you install Quisk.  You must use the 32-bit version even if you have 64-bit Windows because the Quisk extension module is 32-bit.  Quisk installs itself as a package under site-packages under Python 2.7.  To uninstall Quisk, use Control Panel/ Add Remove Programs.  You may need to adjust the config file parameters data_poll_usec and latency_millisecs depending on your hardware.

Before installing Windows Quisk, first think about whether you really want to do that.  Quisk is a simple SDR program meant for experimenters and homebrewers.  It doesn't have all the features of PowerSDR, and it has no menus to adjust its parameters; you must edit a config file to even change the sample rate.  But you can easily write your own Python code to control its behavior, and I find it more than adequate to run my station.

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.

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

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.

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 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 without menus and 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 yellow is the data part of the CW segment.  The band plan and colors are in the configuration file quisk_conf.py so you can change it.
