This article has been multiposted, please ignore this copy and respond
in sci.astro.seti to avoid fragmenting the discussion.  It has also
been duplicated in that group, so it would be best to use only the 
first copy, or the first copy that receives a reply, and cross-post
into this group.

To the author, please learn how to cross-post - if necessary  change
your newsreader.  (You may possibly find some newsreaders reject
the article because they don't know how to handle Windows 1255, even
though the article is ASCII mis-represented as that.)
