Spectrum Search Lite

Spectrum Search Lite is a graphical software tool designed to search and display data contained in the Register of Radio Frequencies (RRF).

About the database

The Spectrum Search Lite database is supplied in Microsoft Access 2000 format. It contains the majority of licence information that is held in the Register of Radio Frequencies (RRF).

Limited information is available via the Spectrum Search Lite user interface — however, this information can be accessed directly via the Microsoft Access database through queries or interfaces with any user tools.


The Spectrum Search Lite software and database are available for download from the links below. The database is currently refreshed weekly, usually on a Monday.

Note: We have had to update the PRISM.MDB database version to Access 2000. The Spectrum Search Lite application has also been updated (version 1.0.5) to perform better with the Access 2000 version and Windows 32 & 64 bit versions. Please uninstall the old version before installing the updated one.

The information contained within the Spectrum Search Lite database is not a complete set of information from the Register of Radio Frequencies, as there has been some information deliberately withheld as per section 28 (3) of the Radiocommunications Act 1989(external link).

The data provided is current as at the date of the production stated on the opening screen. Radio Spectrum Management will not be responsible for any incorrect or incomplete information contained in Spectrum Search Lite.
