A Standard Clear Frequency, or SCF, was a communications frequency which was used for public communications. Uses for Standard Clear Frequencies included starships contacting spaceports about landing instructions, governments broadcasting information to a specific area, civil defense warnings, providing information about local laws, and the locations of nearby facilities, including ones dedicated to medical, educational, and governmental purposes. Comlinks monitored Standard Clear Frequencies.
