Looks like this person has "EMERGENCY COORDINATOR" in his station status. Xastir has for many years interpreted any packet with EMERGENCY in its entire line as an emergency beacon, a behavior that I think inherited from APRS+SA, but not something that the spec requires (near as I can tell, the spec only requires recognition of the Mic-E emergency message). I always found that annoying, especially because people like to create objects with status text like "EMERGENCY OPERATIONS CENTER" or "EMERGENCY SERVICES" or whatever, and every time they do it triggers an Xastir emergency alert dialog. They usually change that to EOC or something after being asked politely. Honestly, I think the feature is incorrectly implemented, and we shouldn't be keying off randomly placed presence of the word "EMERGENCY" in a position report. It looks like N4GLE changed his station status to "DISTRICT E AL EC" instead of "DISTRICT E AL EMERGENCY COORDINATOR" at around 15:38 MDT, and it was beaconing the longer one right up until then. My guess is that these notifications are going to stop now. Xastir has a hard-coded distance check of 280 miles. If a station saying it's got an emergency is closer than that, it pops up the notification dialog. This 280 mile thing seems absurd, and the comment indicates that it is computed base on a 4-hour trip at 70mph. I rather doubt that anybody who plans on answering APRS emergency calls will be traveling 4 hours at 70mph to get to the emergency. You could change the variable "emergency_range" in db.c from 280.0 to something like what you'd actually be willing to travel to respond to a station reporting a real emergency. -- 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 [email protected] http://xastir.org/mailman/listinfo/xastir
