They are indexed by sender's call, so there can be multiple
BLN1's for example.

Also, in the D700 and D7 and all other APRS software, you can
also set up MSG groups.  Just add "VWS" to all of youir
participant's MSG lists and then any message sent to "VWS" will
go to all of them without bothering everyone else.

There is no ACK, but it will be sent 5 times which is sure to
get to everyone.  So I would use BLN# for general announcements
to ALL aprs mobiles in the surrounding areas, and use team
specific messages to VWS so that all in your group see them, but
they  don't fill up everyone elses message buffers.

Remind everyone to keep their message buffer cleared of old
messages, or they might start rejecting them.  They can only
keep 10 (or is it 16?)...

APRS.  Its not just icons on a map...
