Since 2005 the _WSJT_ project (including programs _WSJT_, _MAP65_,
|
|
|
|
|
|
_WSPR_, _WSJT-X_, and _WSPR-X_) has been ``open source'', with all
|
|
|
|
|
|
code licensed under the GNU Public License (GPL). Many users of these
|
|
|
|
|
|
programs, too numerous to mention here individually, have contributed
|
|
|
|
|
|
suggestions and advice that have greatly aided the development of
|
|
|
|
|
|
_WSJT_ and its sister programs.
|
|
|
|
|
|
|
|
|
|
|
|
For _WSJT-X_ in particular, we acknowledge contributions from *AC6SL,
|
|
|
|
|
|
AE4JY, DJ0OT, G4KLA, G4WJS, K3WYC, KA6MAL, KA9Q, KB1ZMX, KI7MT, KK1D,
|
|
|
|
|
|
PY2SDR, VK3ACF, VK4BDJ, W4TI, W4TV, and W9MDB*. Each of these
|
|
|
|
|
|
amateurs has helped to bring the program’s design, code, and
|
|
|
|
|
|
documentation to its present state.
|
|
|
|
|
|
|
|
|
|
|
|
Most of the color palettes for the _WSJT-X_ waterfall were copied from
|
|
|
|
|
|
the excellent, well documented, open-source program _fldigi_, by *W1HKJ*
|
|
|
|
|
|
and friends.
|
|
|
|
|
|
|
|
|
|
|
|
We use development tools and libraries from many sources. We
|
|
|
|
|
|
particularly wish to acknowledge importance of the GNU Compiler
|
|
|
|
|
|
Collection from the Free Software Foundation, the "clang" compiler
|

from LLVM at the University of Illinois, and the Qt Project from Digia
|
|
|
|
|
|
PLC. Other important resources include the FFTW library by Matteo
|
|
|
|
|
|
Frigo and Steven G. Johnson; SLALIB, the Positional Astronomy Library
|
|
|
|
|
|
by P. T. Wallace; and a high-precision planetary emperis and
|
|
|
|
|
|
associated software from NASA's Jet Propulsion Laboratory.
