Re: [amsat-bb] PREDICT Version 2.1.0 For Linux Released

["ae4gb" <ae4gb@xxxxxxx>]

Hi Jaime
I have the Meade Autostar controller.  You can directly enter the keps into
it for auto tracking.  I haven't tried to visually see the satellites with
it yet but plan to try mounting my Arrow Antenna to it.
