Subject: [WriteLog] MMTTY 1.63b test results in the XE RTTY contest

Coincidentally,

action was pretty

plain bad and I

problem or crash.
> At one time, I changed the priority on computer B to "higher" instead of
"highest" in the
> MMTTY setup. When I did this, it crashed almost immediately so I went
back to "highest".

determine if there

so.
