[Xastir] Receiving messages

There is also the point that the mobile station may be, well, mobile. I'm
not going to be trying to type a reply to a station when I'm doing 60-70 mph
down the road.

An inordinate fraction of mobile stations are basically configured as
trackers that don't even display received messages.  Odds are good that
you're trying to communicate with one of those.

APRS messaging is one of the great underused and underappreciated
capabilities.
The vast majority of users have come to treat APRS as nothing more than a
vehicle tracking system (worse yet, as a one-way position transmitting
system with the only receivers of value being the internet gateways and
web-based APRS viewers).

In my experience, even those who are running mobile stations that *can*
receive messages tend to ignore them (many D700 and D710 users even ignore
so many messages their message buffer is full and their stations just return
the code that says the message is rejected).  Does XASTIR show that your
messages are being ACKed by the target station?  

As for your query about why your station doesn't show up in the mobile
stations list, I can't really answer that definitively.  I tried digging
through the code quickly to understand how the different lists are
populated, but I can't spot how it actually distinguishes between mobile and
otherwise --- I'm pretty sure that it figures that out based on whether the
station is transmitting course and speed.  Does your mobile station have a
GPS attached?
