After installing NAVSTAX v1.80502 and configured for P3Dv4 the airplanes panel.cfg file was not updated until I selected P3Dv3!
However the bigger problem is that the NAVSTAX avionics displays (freq,..) turn only on when ? aircrafts like P38L or PC-6 Porter are selected.
With the default Maule, F35,… or Caronado PA-28 Archer II the displays are blank.
Only the squelch sound is audible! With FSUIPC I monitored avionics and battery power sources.
But there is no difference to ? planes.
Appreciate any help to get the stack working also for the default planes.
