Hi Joe,
On my MacBook (running r4609) I see the 35% difference as well...

Hi Bill,
Yes, there are many possible ways to take advantage of FFTW's wisdom
capability. I've been using it for some years now -- both for
professional research purposes and in MAP65, which processes a 96 KHz
signal bandwidth in each of two polarizations and thus has much higher
CPU demands.

Hi Joe,
Tested with both JTSDK-QT v1.0.0 and JTSDK v2.0.0. Both run fine after
the last update. I used the respective build environments, removed the
path prefix in wisdom1.bat, everything worked fine.
I can add this optimization to the build script if you like, I just need
to know all the input

I think you'll find that timer.out is OK. It will be flushed (and
therefore contain its timing information) upon program exit.

How did you get a line# and I didn't???

Hi all,
I have committed some changes that significantly improve the decoding
speed of WSJT-X in both modes, with no change in its effectiveness.
The changes affect only the jt9.exe executable.
One of the changes is to make use of the "wisdom" feature in FFTW. This
requires running the program
