Whenever a new report comes in from the selected station, the weather window is automatically updated. These reports are typically broadcast every 9 minutes. The report is also available at anytime if an APRS user sends the WX station an APRS Query, or the all-call WX query. Any station may place a storm or other object on his map, and it will be transmitted to all other stations. If the object is given a course and speed of advance, then it will be automatically dead-reckoned on all screens until the next update.
Any station can update the location of an object.
The updating station will overwrite all posits in the net and will become the new reporting station. This prevents duplicate reporting and eliminates dependency on the original posting station. It will also show the radius of the winds with colored circles. To hook one of these objects on the map, you must hook the little gray circle which marks the position of the actual report, and not the symbol itself. After two hours with no update, the symbol fades to dark gray.
