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 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. You can install Quisk with either the binary installer or the source tarball. But 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 configuration 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.
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 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 and look for error messages if anything goes wrong. But you must create menu items and shortcuts yourself.
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. Quisk offers these capabilities:
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.
As a transmitter it can accept microphone input and send that to
your transmitter for SSB operation. For CW, QUISK can mute the
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 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.
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.
