[amsat-bb] Fox Telemetry Decoder Software Version 1.0 Available for Download

[Chris Thompson]

Stefan,

thanks for the feedback.  I exchanged emails with Don earlier in the
project.  There is no way to read the Az El information from MacDoppler
currently.  I'm open to supporting it in the future if that feature becomes
available.
