[amsat-bb] Antenna Rotator Alternative

[Pedro Converso]

Hi Scott,

Clever idea, will try !

If you want to get rid of paper predictions try http://amsat.org.ar/pass.htm

Will give you an easy & intuitive azimuth/elevation graphic and actual
doppler corrected frequencies while the bird passes.

Also will work offline internet at the field from your smartphone/tablet.

Good luck with your innovative setup !
