Hi Steve, To be honest, I think particular testing is best left to those of you that know exactly what's going on and how best to test it. I would probably just add confusion to the subject at this point.
Presently, the WSJT-X build script on Linux compiles wsprd_exp, but it is not copying too / overwritting the wsprd binary ( if I recall correctly ). If this is something desired for Windows, I could add the commands to build it for testing. I'm working on a couple of updates for JTSDK Win32 to enable / disable Qt5.5 testing. After that I'll give it a shot and post my findings to you all off list so as to not clog up the devel list with my wayward ramblings :-) 73's Greg, KI7MT On 7/28/2015 1:49 PM, Steven Franke wrote: > Hi Greg and Joe, > > As Joe said, the stack decoder is only in wsprd_exp and it requires a > command-line argument (-J) to activate it, as the default algorithm in > wsprd_exp is the Fano algorithm. > > The tests conducted by me and Joe show that my implementation of Jelinek’s > stack-bucket algorithm doesn’t seem to provide any significant advantage over > the Fano decoder in the wspr application.
