Here I find the following: When jt49sim is commanded to produce a jt4 wave file it produces a jt9 wave file, e.g. the command:
jt49sim "K1ABC W9XYZ EN37" 4C 1 0.0 0.0 1 -15 produces a JT9C wave file instead of the expected JT4C wave file, even though the console message says that a JT4 wave file is being created: ===============console message follows================ C:\JTSDK\wsjtx\garc\qt52\1.9.0\Release\install\bin>jt49sim "K1ABC W9XYZ EN37" 4C 1 0.0 0.0 1 -15 File Sig Freq Mode S/N DT Dop Message ------------------------------------------------------------ 1 1 1000.000 4C -15.0 0.00 0.0 K1ABC W9XYZ EN37 ===============end of console message================ The wave file produced is a JT9 wave file: http://w3sz.com/JT4C-Original.wav So whether the specified mode is "4" or "9", a JT9 mode wave file is always produced. This is so with version 1.9.0-rc4 r8642 from directory C:\JTSDK\wsjtx\garc\qt52\1.9.0\Release\build (which I copied to ..Release\install\bin) compiled locally using JTSDK 2.0.6-0 Release r715. This is true for all sub-modes JT4A-G. I thought that the likely culprit causing this problem was line 56 in jt49sim.f90, "imode = 9" which is placed right before the imode "if" statement, which you can see here: https://sourceforge.net/p/wsjt/wsjt/8642/tree/tags/wsjtx-1.9.0-rc4/lib/jt49sim.f90 I suspect that this line was accidentally left in place after it was added during debugging. Removing line 56 ("imode = 9") and recompiling corrects the problem so that JT4 files are produced by the "4" option and JT9 files are produced by the "9" option. A wave file created using the same command line as was given above, but after the correction to the code as just described, is here: http://w3sz.com/JT4C-Corrected.wav 73, Roger Rehr W3SZ ------------------------------------------------------------------------------ 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
