HI John,
All that you described can be done automatically and without effort by a
great amateur program: SALLY 7.
The author is Ted G8NPF, we convinced him to resume the upgrade to the
operating system 7, because he had abandoned the project with the end of the
XP operating system.
With great spirit of collaboration has begun to program and re-create that
wonderful piece of sofware which was "Sally 4" for XP.
Now the program is almost ready, it works great and if you want to be a
Sally fan, you can download the program or from my website, which see below,
or you can do so by accessing the Yahoo Sally Group.
Frase del giorno:
Give me a firm spot on which to stand, and I will move the earth. Archimede
73 Ciao a tutti Renzo.
