Hi John,
I’ve just checked the PAW Database, and while there are loads (probably hundreds) of reports from your aircraft, over the period since 25th February 2021, from a significant range of PAW ATOM Ground Stations, I can’t find one single report of a FLARM transmission from that Hex ID.
This clearly indicates that either your Flarm device isn’t transmitting OR that it is transmitting a different ID (such as its default FLARM ID) from your aircraft (hence it won’t show up on a Vector (or database) search using the aircraft HexID).
Worth checking that your FLARM Firmware has been updated in the last 12 months (as per Steve’s post above - certainly not a stupid question Steve) and that it is configured to transmit your Aircraft ID, NOT the default FLARM one before you even think of sending it back to Switzerland.
Please let us know what you find.
Best Regards
Peter
