Here is the track.
Additionally I chose the NDB Gali (525kHz), which worked.
It's a mission running on a server. In the track she was played offline as SP. The error sometimes also occurs in the quick start mission.
Edit:
To rule out that it is up to the mission, here again a quick start mission. As a reference, the NDB Gali was taken again and then the Kutasi NDB. l39_ndb.trk l39_ndb_2.trk
