Kind of like we do in Xastir with Mic-E or NMEA positions if you zoom way in: You see a little white box with the station symbol at one corner of the box. The box shows where the station _might_ actually be based on the transmitted precision. Transmit with more precision and the box gets smaller. -- Curt, WE7U: <www.eskimo.com/~archer/> XASTIR: <www.xastir.org> "Lotto: A tax on people who are bad at math." -- unknown "Windows: Microsoft's tax on computer illiterates." -- WE7U The world DOES revolve around me: I picked the coordinate system!
