[amsat-bb] A refresher needed...

I have had several successful QSOs via the Space Station APRS repeater 
(ARISS). I use DireWolf and UISS software. The UISS software allows you to 
set up macros to send short messages via packet. Put your call, name, and 
grid square in there. You send that, get a confirmation from the other 
station and they send their info, then you send a confirmation back.
A digital satellite QSO in a matter of seconds.
You really need to listen carefully so you don't send in the middle of 
another person's packet to prevent packet collisions.
It doesn't always work, but when it does it work, it's pretty cool.
