Certain job specific frequencies often go unused

I agree that some channels are underused (Civ specifically) but big disagree on merging channels. Like people mentioned, i really don't want Research adventure chatter to clog up important medical chatter or something allong the lines.

You also need to take into consideration how the departements work, in Research and Medical for example, constant radio chatter isn't always necassery, often times your colleague is around the corner unlike for example Security where each officer might be patrolling on seperate parts of the station.
