[amsat-bb] APRS birds

Hi all,

There was a comment on the recent experimenters thread about using the APRS birds. I'm new at this game - I've made 2 satellite QSOs so far - and would love to know more. Is there a good document on how to use these satellites, and maybe some tips on how to get a TH-D72A to do it? I've only used it to beacon APRS, messaging with the service isn't something I've tried.

Thanks and 73, Sean WA1TE
