[amsat-bb] Update: Rent GEO bandwidth for US

[John Kludt]

MIchelle,

Every disaster drill I have ever done makes the assumption that the
Internet is *not* available.  Will this system work without Internet
access?  It could still be fun to play with and do proof of concept work
but absent the Internet might not be too useful in an emergency setting.

Please clarify.

John
