Radio Management


Investigation of interferences

The integrated radio monitoring network was set up to consolidate one satellite radio monitoring center(SRMC) and ten regional radio management services into a network on a nationwide scale. Each region operates one regional station and multiple local stations. The CRMS is in charge of commanding and controlling these stations.

The CRMS measures the deviation in frequency tolerances, occupied bandwidth and spurious emission intensity are determines whether they are in conformity with the Radio Regulations in Korea.

The CRMS monitors radio waves emitted from the radio stations to determine
whether the licensed radio stations are working properly and the quality of radio
waves emitted by them conforms to the technical standards.

The CRMS carrys out monitoring activities in the blanket area except for fixed
monitoring and low-power radio station monitoring in the frequency range, and
finds the violations of the radio regulations.
  • · Detecting and tracking of illegal radio frequencies
  • · Monitoring of radio qualities
  • · Monitoring of radio operating conditions

Monitoring for the safeguarding of human life and property

The CRMS monitors international distress frequency 24 hours a day for the safeguarding of human life and
property. The CRMS is also in charge of monitoring services for important communications (related with dis-
tress, urgency, safety, and emergencies) performed by vessels and aircraft, and supervising them not to
cause interference and jamming.

Voluntary monitoring of amateur communications and support for the KARDF contest

To establish a healthy operating environment for amateur radio communications in Korea, the CRMS organized
regional voluntary committees to monitor HAM activities against illegal operating items. The Korea Amateur
Radio Direction Finding (KARDF) contests are held by under the joint auspices with the KARL to promote ama-
teur radio usage throughout the country.
