# Spectra Radio Services & Devices

The Spectra Radio Services and Devices package includes a series of standard SCA compliant components that implement the Application Programming Interfaces API’s published by the Joint Tactical Networking Center (JTNC). These, together with the SCA Core Framework control components, provide radio platforms such as the Spectra DTP4700 with an SCA compliant platform offering software radio application providers the opportunity to develop and test portable waveforms that rely on a wide range of functionality supporting audio and data networking capable radios.

The Spectra Radio Services and Devices package is an optional extension to the Spectra DTP4700 platform. The implementations were designed to be portable across platforms and are not exclusive to the Spectra DTP4700.
