The _WSJT_ project was started by *K1JT* in 2001. Since 2005 it has
|
|
|
|
|
|
been an Open Source project, which now includes the programs _WSJT_,
|
|
|
|
|
|
_MAP65_, _WSPR_, _WSJT-X_, and _WSPR-X_. *G4WJS* (since 2013) and
|
|
|
|
|
|
*K9AN* (since 2015) have made major contributions to _WSJT-X_.
|
|
|
|
|
|
Together with K1JT they now form the core development team.

All code in the _WSJT_ project is 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, G3WDG, G4KLA, IV3NWV, IW3RAB, K3WYC, KA6MAL, KA9Q,
|

|
|
KB1ZMX, KD6EKQ, KI7MT, KK1D, ND0B, PY2SDR, VE1SKY, VK3ACF, VK4BDJ,
|
|
|
|
|
|
VK7MO, W4TI, W4TV, and W9MDB*. Each of these amateurs has helped to
|
|
|
|
|
|
bring the program’s design, code, testing, and/or 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
|
2015-11-15 15:01:57 +00:00

by P. T. Wallace; and a high-precision planetary ephemeris and

|
|
|
|
associated software from NASA's Jet Propulsion Laboratory.
