Hi Joe,

Nice you are back on chasing birds ! Hope you get along and enjoy.

Thanks! for your comments on http://amsat.org.ar/pass.htm.

This app keplerians are updated 4 times per day, so don't need to
update, it should take your location, local time and timezone by
itself, further new sats get automatically its way into the
application since launched.

Pass should also work on all sort of browsers and Op.Systems as well
as portable devices running android (smartphones, tablets, etc)
allowing to work birds on the field.

If using win, you can try the executable version at
http://amsat.org.ar/pass.exe that with driver
http://amsat.org.ar/wispdde.exe should handle rotor and Dopplers.

Pass is a cooperative effort where many users had contributed to keep
it simple and usable.

So, welcome to space, wishing good luck kicking the amazing tin birds
we have nowadays.

73, lu7abf, Pedro Converso
