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? -- Tom Russo KM5VY Tijeras, NM echo "prpv_a'rfg_cnf_har_cvcr" | sed -e 's/_/ /g' | tr [a-m][n-z] [n-z][a-m] _______________________________________________ Xastir mailing list Xastir@lists.xastir.org http://xastir.org/mailman/listinfo/xastir
