Successful upgrade of Continental Electronics shortwave  transmitter using RFmondial’s DRM/AM exciter LVe

In late 2023 RFmondial got the task to replace a malfunctioning Transradio DMOD3, which was feeding a Continental Electronics short-wave transmitter located at Kajang site. This traditional Malaysian site can be heard since the 1970’s all around the world and it stands out with its massive antenna masts located south of Kuala Lumpur.

The upgrade of the transmitter was necessary, as Transradio is not on the market anymore and spare parts are not available. RFmondial’s broadcast exciter LVe has been designed exactly for this specific task such that upgrading older transmitters is still possible and preventing the need to invest into a new transmitter. The LVe is a fully digital broadcast exciter, tuneable within the longwave, mediumwave and shortwave frequency bands as well as in VHF. Furthermore, it meets the demanding performance requirements of Digital Radio Mondiale (DRM) broadcasts as well as pure analogue AM and simulcast transmissions.

Although the upgrade at Radio Televisyen Malaysia (RTM) was mainly targeted to continue the analogue shortwave program of RTM Wai/Limbang FM, the transmitter can now be prepared to provide digital broadcasts as well. Dr. Albert Waal, Head of Hardware Development, and responsible for the upgrade of the transmitter station says: “It was a great honour to upgrade this famous Malaysian transmitter site and to work with the very professional and kind staff of station manager Azizi Yusuf and his team.”

This installation queues into the aim of RFmondial to be the world-leading company in upgrading existing high-power transmitter installations of various makes and models like RIZ, Continental Electronics, Transradio, Thomson, or GatesAir.
