Editing Subcarrier (section)

==Telemetry and foldback==
Many stations use subcarriers for internal purposes, such as getting [[telemetry]] back from a remote [[transmitter]], often located in a difficult-to-access area at the top of a mountain.  A station's engineer can carry a decoder around with them and know anything that is wrong, as long as the station is on the air and they are within range.  This is the essence of a [[wireless]] [[transmitter/studio link]].

On wireless [[studio/transmitter link]]s (STLs), not only are the broadcast station's subcarriers transmitted, but other [[remote control]] [[Command (computing)|commands]] as well.

[[Interruptible foldback]], such as for [[remote broadcasting]], is also possible over subcarriers, though its role is limited.
