An Open Source version of it can be downloaded to create your own receiver/transmitter. For Virtual Instrumentation enthusiasts, LabVIEW has been used to develop a DRM system detecting the envelope of the AM signal through sampling. The paper goes on to give a model for managing DRM signals using LabVIEW as a “communications toolkit.”
The University of Illinois has an ECE course focused on pulling data off-the-air. They use LabVIEW among other tools to develop their experiments as DRM is a focus area for them.
