[amsat-bb] Outernet L-Band now carries AMSAT and ARISS weekly bulletins

The Outernet L-band feed is now carrying a condensed version of the AMSAT
and ARISS weekly news files.  (Global Geosat coverage except for Northern

Receivers are simple:  http://aprs.org/outnet.html

For ARISS, I manually added a 2 char grid square to each school listed in
the school schedule and am asking the outernet folks to parse out that
location info and plot a 1200 km footprint on their weather globe showing
where people can tune in the ARISS contacts.  Then their RTL-SDR dongle
could then actually be retuned to hear the contact.  Just an idea...
