The purpose of the WSJT Development Group is to design digital protocols for weak-signal communication, develop software to implement these protocols, and make it available to the Amateur Radio community. On occasion we have aided the selection and adoption of conventional frequencies on which our protocols can be used, but it is actually the users themselves who make the important decisions. We have never taken a leading role in setting boundaries of sub-band segments for any particular purpose, and -- speaking for myself -- I am certainly not prepared to suddenly recommend commandeering 20 kHz of spectrum on any HF band for exclusive use of JT65 and/or JT9. ... While I have your attention, I must remind you of obligations you assumed under the GNU General Public License (GPL) when you copied the source code of WSJT-X, made some changes, and renamed it as "JTDX vXX.X ... by UA3DJY". 1. Compliance with GPL requires that a derivative work (such as JTDX) must be licensed in a compatible manner. Just saying "It is open source software distributed under the GPL v3 license" is not enough. Apparently a significant fraction of JTDX distribution takes place from the web site http://jt65-dx.com/download/wsjtx-ua3djy.html . 2. I see nothing on that web site mentioning any license requirement. 3. I see a JTDX screen shot in which the main window title is given as "WSJT-X v1.7.0-devel JTDX v16.6 ... by UA3DJY." We have never released a program called "WSJT-X v1.7.0-devel", so I would not expect to see such a designation on a derivative work. 4. Describing JTDX as "by UA3DJY" is surely misleading, and a violation of the copyrights on our code. Probably >90% of code in your derivative work was written by someone other than yourself. 6. Finally: if you were truly committed to the Free Open Source Software (FOSS) philosophy, I would expect your development work to be organized in a way so that can give back to, as well as take from, the amateur software development community. I can see no evidence that you are doing this, for example with an open source-code repository. -- 73, Joe, K1JT ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
