Which statement best describes Link 11?

Explanation:
Link 11 is a legacy tactical data link used by NATO and allied forces to exchange command and status information over radio nets. It transmits data by modulating a carrier to create a composite audio signal, with the data encoded through phase shifts within that audio. This combination of being an older, NATO-focused system and using phase-modulated data carried in an audio signal is what this description captures best. The other statements don’t fit: Link 11 is not the newest system (Link 16 has largely superseded it in many roles); it isn’t restricted to satellite communications; and it doesn’t rely on liquid crystal displays for its operation.
