What is WOLF ?
WOLF was written by Stewart Nelson (KK7KA). It means "Weak-signal Operation
on Low Frequency". WOLF can operate over a wide range of signal levels. For
example, a WOLF beacon transmits a 15-character message repeatedly. If the
received signal would be adequate for conventional CW, copy will be displayed
in 24 seconds.
What is the WOLF GUI ?
GUI means "graphic user interface" in this case. The original WOLF implementation by KK7KA was a simple WIN32 console application. I (DL4YHF) tried to write a user interface for it in April 2005, using Borland C++Builder V4. At the moment, this is still "under construction", so please don't expect too much. The plan was...
In the meantime, some "slow" and "fast" modes have been added in the WOLF GUI. Thanks to Ko, NL9222, for suggesting and testing these new modes !
To take a look at the user interface, look into the manual which is
here. You can download everything
(including the manual) from this site, it may include the slightly modified
"WOLF CORE" which was originally written by Stewart. Again, my only contribution
so far is the user interface, and some trivial adaptions to compile the sources
with Borland C++Builder. A short description of the graphic user interface
is contained in the zipped archive ( in the "html" subdirectory) . The
WOLF core algorithms are built into the GUI version, so you don't have to
download the original console application to run the GUI variant.
(Ok, I hate this paranoid stuff, but someone told me it's wise to have it here..)

WOLF was developed by Stewart Nelson (KK7KA). The user interface was written by Wolfgang Büscher (DL4YHF).
The program must not be used in 'critical' environments, where program failure may cause harm to persons or damage to property. Dont rely on this program as an emergency communication medium !

To install, simply unzip everything into a directory of your choice (be sure
to keep the subdirectory structure within the archive). Under "Vista", Windows 7,
and possibly any later windows version, do NOT place this
directory under the windows 'Programs' folder (or whatever the name of that
folder may be) because in that case, the program may not have write permission
to "its own" files (which it places in the same directory where also the executable
is located - for example, "wolfcfg.ini" which stores the configuration data).
2013-02-16 : Added support for 'new' sampling rates for the soundcard
2008-01-16 : Added two selection combos for the "input" and "output" audio device.
