Do the radio stations need new transmitters to transmit DRM signals?
Existing transmitters can be modified.
Many existing transmitters which are now being used for analog broadcasts can be modified so that they will be suitable for DRM. Our current DRM test is run using modified transmitters. In some cases, however, a modification of the existing equipment is not worthwhile and the installation of a new transmitter more favourable. Both older modified transmitters and new DRM transmitters can be used for analog transmissions as well. Even the parallel radiation of analog and digital signals is possible with DRM transmitters.
