The question mark icon is for stations with unknown positions. A station that sends a status message, telemetry, or positionless weather report first (as far as your station newly listening is concerned) means that YAAC doesn't know where to plot it or
what its symbol is. So YAAC guesses the station's location by assuming it's near its first digipeater (assuming the digipeater's position report has been heard). This feature is called "vicinity plotting".
Once YAAC hears an actual position report with an APRS symbol code from the station, it will change the icon and move it to the correct location on the map.?
While the station's actual position is not known, and either it wasn't digipeated and heard by an I-Gate whose position isn't known, or digipeated by a digipeater whose position isn't known, the position remains at latitude/longitude (0,0). The button
on the map toolbar with a big 0 on it will jump the map to that location.
Note that, if you don't like it, you can turn vicinity plotting off in the expert-mode configuration dialog.?
Hope this helps.

Subject: [yaac-users] Strange Position Reports
I see periodic objects show up with the icon of a gray circle with a red
question mark. They are many miles from their actual location. Clicking
on the icon gives me a box of either seemingly garbage characters or
just a blank in the comments field. Many of these are fixed sites, so I
know the location is not correct. Some are mobile, but when I talk to
them later, they were never in the area.
What's up with that?
