Spectrum Search Lite

Spectrum Search Lite is a graphical software tool designed for searching and displaying data from the Register of Radio Frequencies (RRF). This service allowed users to access licence information contained in the RRF, presented in a Microsoft Access 2000 format database. Although Spectrum Search Lite is no longer offered as a service, the tool is still available for download. However, it's important to note that the database within Spectrum Search Lite is no longer being updated; the last update was performed in December 2022.

About the database

The service was provided through a graphical software tool and a Microsoft Access 2000 format database. The database contained licence information from the RRF, and while limited data was accessible through the user interface, more comprehensive information could be accessed directly via the Microsoft Access database.

Note: We undertook an update to the PRISM.MDB database version, transitioning it to Access 2000. Additionally, enhancements were made to the Spectrum Search Lite application (now at version 1.0.5) to optimize its compatibility with the Access 2000 version as well as Windows 32 & 64 bit editions. Although this service is no longer available, you have the option to download the latest version if desired. Before installation, it's recommended to uninstall any previous iterations.
