Re: [wsjtgroup] FSK441 using antenna elevation
- Bob --
You are exactly right: the elevation displayed on the WSJT screen is the
optimum elevation for meteor scatter signals on the specified path. If
your antenna directivity is sufficient to make a difference, your number
of good meteor reflections will be optimized by setting your elevation
to that number.

the elevation seems to help anyway . I figured I need all the help I can
get and when WSJT9 said Az 25 and EL 16, I did just that. And besides
that, the ground noise goes away.
