Dear Bill, did that, but still it takes too much time
./wsprd -f 7.0386 wspr_7038600160310_1944.wav real 2m11.568s In case I do it with a version compiled with the Makefile in the wsprd folder (modified with the compiler flags - got this one form Pavel) and now it is MUCH faster (everything still decodes ...): time ./wsprd -f 7.0386 wspr_7038600160310_1944.wav real 0m20.086s time ./wsprd -f 7.0386 000000_0001.c2 real 0m7.703s @Steve: Yes that gives ~2sec The idea is to receive all ham-bands simultaneously, with an SDR and a multi-band antenna you can do that. This drastically reduces the time you have: i.e. for 8 bands: 120 s/8 = 15 s (which works now for c2 files) The platform is a RedPitaya, which also serves as the SDR receiver. Pavel has done some great work, so one can use the RedPitaya as an SDR now: http://pavel-demin.github.io/red-pitaya-notes/ 73 de PA7T / Clemens Am 15.03.2016 um 14:44 schrieb Bill Somerville <[email protected]>: > On 15/03/2016 13:34, Bill Somerville wrote: >> rm CMakeCache.txt >> CFLAGS="-Wno-missing-braces -march=armv7-a -mcpu=cortex-a9 -mtune=cortex-a9 >> -mfpu=neon -mfloat-abi=hard -ffast-math" \ >> CXXFLAGS="$CFLAGS" \ >> cmake -D CMAKE_INSTALL_PREFIX=/root/src/wsjt/src/build/Debug/ \ >> CMAKE_PREFIX_PATH=/root/src/hamlib\ >> /root/src/wsjtx/src > Hi Clemens & Pavel, > > sorry, I have mixed up release and debug configurations there, I should have > written: > > rm CMakeCache.txt > CFLAGS="-Wno-missing-braces -march=armv7-a -mcpu=cortex-a9 -mtune=cortex-a9 > -mfpu=neon -mfloat-abi=hard -ffast-math" \ > CXXFLAGS="$CFLAGS" \ > CMAKE_BUILD_TYPE=Debug \ > CMAKE_PREFIX_PATH=/root/src/hamlib\ > /root/src/wsjtx/src > > or > > rm CMakeCache.txt > CFLAGS="-Wno-missing-braces -march=armv7-a -mcpu=cortex-a9 -mtune=cortex-a9 > -mfpu=neon -mfloat-abi=hard -ffast-math" \ > CXXFLAGS="$CFLAGS" \ > cmake -D CMAKE_INSTALL_PREFIX=/root/local/ \ > CMAKE_PREFIX_PATH=/root/src/hamlib\ > /root/src/wsjtx/src > > Although I would not use root at all for development! > > 73 > Bill > G4WJS. > ------------------------------------------------------------------------------ > Transform Data into Opportunity. > Accelerate data analysis in your applications with > Intel Data Analytics Acceleration Library. > Click to learn more. > http://pubads.g.doubleclick.net/gampad/clk?id=278785231&iu=/4140_______________________________________________ > wsjt-devel mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/wsjt-devel ------------------------------------------------------------------------------ Transform Data into Opportunity.
