Hi Edson, that was going to be my first question if it is not clear from the upload specification how to identify balloon telemetry. A quick scan of the web site info implies that he frequencies used are the existing WSPR and JT-9 HF frequencies on 20m and 30m, if that is so then many stations could be uploading valid telemetry just by using WSJT-X for normal HF use. This is a good thing but as you say if there is no way to distinguish the balloon sending stations, then the server needs to be able to do the filtering and also to cope with the many- fold increased traffic. 73 Bill G4WJS. ------------------------------------------------------------------------------ _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
