Viernheim, Hannover, 12.09.2025 – The latest innovation in broadcasting technology has been unveiled at IBC 2025 in Amsterdam, as Plisch and RFmondial showcase the world’s first multi-channel DRM transmitter in VHF Band III (174 to 240 MHz) at booth 8.B63.
With Indonesia recently recommending Digital Radio Mondiale (DRM) for VHF band III, there has been a growing demand for broadcasting equipment in this frequency range. In response to this need, Plisch and RFmondial have teamed up to combine Plisch’s Medium Power Transmitter 5600 / 5700 Series (ranging from 500W to 20kW) with RFmondial’s digital DRM modulator/exciter LV5e. This cutting-edge modulator is capable of merging up to 15 DRM-FM streams into a single spectrum, with each DRM signal featuring its own unique content and power level. The multiplexed spectrum is then transmitted through the Medium Power Transmitter, where advanced signal processing algorithms such as crest-factor reduction, limiter, and non-linear pre-correction are employed to optimize the signal.
Furthermore, RFmondial’s DRM measurement and monitoring receiver RF-SE is already configured for VHF Band III, providing countries like Indonesia and others around the world with the necessary equipment to establish DRM broadcasting networks in this frequency band.
Plisch GmbH, founded in 1955 and headquartered in Viernheim, is a leading developer and producer of radio transmitter systems for TV and radio broadcasts worldwide. With over 20,000 installations in more than 60 countries, Plisch has played a key role in the expansion of national DAB+ broadcasting networks and continues to be at the forefront of innovation, particularly in the implementation of broadcasting standards such as DVB-T/T2.
On the other hand, RFmondial GmbH offers a range of professional products and services for the digital broadcasting industry, as well as other sectors requiring innovative hardware and software solutions. Their expertise in research, development, and prototype implementation of transmitter, receiver, and monitoring technology, along with design services for various industries, positions them as a reliable partner in the global market.
In conclusion, the collaboration between Plisch and RFmondial marks a significant milestone in the evolution of broadcasting technology, paving the way for the development of DRM broadcasting networks in VHF Band III. With a focus on quality, innovation, and reliability, these companies are driving the industry forward with their state-of-the-art solutions.
