With the ever increasing demand for radio based services, monitoring of the radio spectrum plays a vital role today in keeping the spectrum clean for authorised users, particularly the emergency services. It is also an essential and integral part of the spectrum management process, producing and evaluating data to aid spectrum managers in their day to day work. The radio monitoring station, located near Baldock in Hertfordshire, is the Radiocommunications Agency's "listening ear" on the radio spectrum.

Although its original role was simply to monitor the international radio circuits operated by the General Post Office (GPO), Baldock now forms the Agency's only 24-hour operational monitoring station which today has a much broader spectrum monitoring capability than when it was originally brought into service in 1929.
