Oh, and I think having a time limit on the display of received
re-assignments would be a good idea so that the re-assigned calls don't
stick in any client that happened to catch the assignment but not the
de-assignment at the end of the event. Say 24 hour reflectivity after
receipt and then you could have the master station send the assignment
periodically during the event just to pick up any newly monitoring
clients. Then after the event, possibly broadcast the de-assignment for
a while (kind of like an object Kill) but still rely on the client-side
timers to take it out anyway.

Do you support assigning tactical calls across the air? That's
something we implemented in Xastir for support of Events, but the

to remember how to send a tactical call assignment.
You mean you can change a station's callsign with a specially
crafted message to the station?
Nope. It's a display-side assignment of a tactical callsign. It
doesn't change the transmitter in any way. For instance, "we7u-12"
might come to help on the Seattle Marathon in November. Without
touching that station at all, I can make that station appear as
"SAG-5" on all APRS+SA and Xastir stations in the area by sending
out a tactical callsign assignment over the air and/or over the
internet.
When done with the event I can resend the tac-call assignments as ""
and "we7u-12" gets displayed again. -
So any direct RF receiver like D7xx and Yaesu's devices will still see
WE7U-12 for this station. Hm, I'd think that's almost worse than not
having the tactical call...
But, I'm not the judge. If you've got it, have you submitted it to
Bob for inclusion in the specs? I'd love to implement it, just for
the compatibility, if you can provide implementation / format details.
