Thanks Bill, that's very useful to know.

If the 64 bit kvasd Joe compiled at omen.com is present, there are

CPU utilization goes to 100 per cent and stays there. Kvasd continues
at 100 per cent CPU utilization even if wsjtx is terminated. Rather than
improving sensitivity by 2 db it makes wsjtx deaf.
The downloadable kvasd is a 32 bit version. Hardly anyone runs 32 bit
Linux anymore.
I finally got the 32 bit KVASD running. I had to poke, prod and cajole
Rawhide (very unstable cutting edge developmental Linux) to install
the required 32 bit libs.
Thanks for putting in such heroic efforts to make the pre-compiled
32-bit kvasd run on your very unstable cutting edge developmental Linux.
We're not necessarily set up to support such systems with
click-to-install packages. Please feel free to volunteer your help, if
you think there is a need.
The KVASD decoder is necessarily an extra nuisance because of its
patented algorithm and non-open source code. However, since 99% of our
users run Windows, the nuisance is well contained in practice.
Moreover, the improved sensitivity of soft-decision decoding makes
KVASD well worth the extra effort -- especially for EME, the original
target purpose for JT65.
Just to fill in a couple of gaps.
I found that the 32-bit kvasd wouldn't run on a vanilla Ubuntu 13.10
64-bit. A quick check with 'ldd kvasd' showed that the library
libgfortran.so.3 in 32-bit form was missing.
Using:
sudo apt-get install libgfortran3:i386
was all that was required to enable kvasd to run. Clearly 32-bit support
libraries aren't present in the current 64-bit Ubuntu but installing the
Fortran library pulls in all the other required dependencies.
