Yeah, it sounds like the radio/TNC/Computer end is running. Hopefully
some of my comments would prove useful to others thinking of trying
ARISS packet.

Yes, this will send the UI packet from you with the quoted text.

Again, yes this is the right format. If W0ABC copies the downlink they
will see your message.

Technically it should work but is not recommended. This is because
your station and the other station will kick into the full AX.25
handshake protocol. If one of the handshake sequences is missed AX.25
will faithfully try, retry, retry, retry to complete the handshake
message. It is likely the pass will be over before the handshake
sequence is completed and you will have not received the text of the
message. The retry'ed handshake messages add as much competition to a
UI channel as do the unattended beacons others mentioned this morning.

I've thought I should make myself a SATGATE because there are so few
active at present. I tend to leave my station off and disconnected
when I'm not operating. I will likely not make my station operate
unattended due to stretches of being away from the radio doing things
like the Journal or news bulletins. 

But when you see packets from me I really am at the keyboard. I'll
look for you on upcoming passes.
