Packet on AO-27

Let us re group on that one. Sure it would be fun and much more
efficient. Now let us consider what AO-27's purpose is. It is an entry
satellite for folks who are getting started and only have FM HT's. Sure
it is misused and sure there is chaos at time. But remember that most of
the digies up there are under used. So lets not take the only toy away a
few "satellite operators" have. If you are already a proud owner of a TNC
lets explore the other possibilities without causing an uproar. 73 de

That's what was so fun about using APRS with MIR.  Of course, packet was
only was to communicate *via* MIR, but had they a simplex repeater or a
transponder on board for voice it would have been chaos.

Using UI frames versus connected packets greatly maximized our chances of
making a contact, and sped up the process of the exchange.  APRS further
sped up the exchange by automating some of the processes, like manually
automatically sending the *same* reply until it got digipeated, versus
retyping the whole line over and over..

Many more QSO's can take place during a pass with packet, versus using
voice.  It's also a lot more fun!!

Needless to say, I am eagerly waiting for what will happen with a digi on
the ISS...
