Hi flyOn,
Please clarify - when you say ‘I run a PilotAware Rosetta in my C42 Microlight with the Trig XPDR’, do you mean separately, or with the Rosetta supplying position data to the Txpdr to provide ADSB Out?
You also say ‘In my other plane (D-MXPD) it runs correct.’
Under normal circumstances, that would lead me to suspect that you aren’t changing the Hex Settings properly in the Rosetta Config when moving the Rosetta between the planes, but you say that ‘you have the correct Hex Address in both devices’. If that is the case, this might be an issue with the reference database used to determine the Aircraft Registration from the received Hex ID.
If you can give us the Hex ID’s for both planes and the name of your base station, Lee should be able to look them up via the network and see what is being received.
Regards
Peter
