Some more good WSJT info.

It doesn't matter how beautiful your theory is, it doesn't matter how smart
you are. If it doesn't agree with experiment, it's wrong.

Nicely summarized, Marshall.
It is also useful to point to the WSJT Group website at
http://www.ykc.com/wa5ufh/. In the left-hand sidebar, you will find an area
called Tutorial Files. There are many files here (including some written by
me, W5WVO) that attempt to summarize boh the basics and the finer points of
WSJT meteor scatter operation.
Rod, WSJT meteor scatter operation is very different both in concept and
practice from making SSB or CW contacts using ionospheric propagation, and
it does have a learning curve to it. Depending on your own personal
proclivities, that learning curve might be easily negotiable, or it might
appear forbiddingly steep -- but either way, it CAN be mastered. Don't give
up. Get help when you need it -- trying your best to make sure that the
person you're getting help from actually knows what he's talking about and
can communicate accurately. Marshall and I are a fairly decent start in that
direction. ;-)
