WMLK orders new shortwave transmitter

Shortwave Transmitter with a Simple to Handle UCS Control Systems

Turgi, Switzerland, November 30, 2017. Ampegon has received a new contract from WLMK Radio, based in Pennsylvania, United States, for development and installation of a new 300 kW high power Shortwave Transmitter with test load, matrix switch and remote control system.

In spring 2017, WMLK Radio's transmitter building caught fire and the previous Ampegon transmitter (originally built in 1975 under our heritage BBC brand, and working reliably until the fire) was completely destroyed. Ampegon is now pleased to be working with WMLK to provide a replacement transmitter as quickly as possible and get their radio station back on-air.

Ampegon will provide our latest transmitter model featuring a high performance PSM power supply, the latest filter technology and Ampegon’s intuitive UCS control system. This allows the entire transmitter to be operated from a single touch screen, or even remotely over the internet. These features provide significant benefits over the heritage generation BBC transmitter, including greater electrical efficiency, significant reliability improvements, and the ability to retune rapidly.

Ampegon’s Radio Transmitter Construction Group aims to give WMLK a high priority in order to have the station back on-air by October 2018.

New transmitters for All India Radio

Press Release

Turgi, Switzerland, August 8, 2013. All India Radio (AIR), India’s National Broadcaster and the premier Public Service Broadcaster of the subcontinent, has ordered two 100 kW shortwave transmitters from Ampegon. The new systems will replace existing analogue transmitters with four tubes by modern analogue/digital transmitters having single tube and hence a much better overall efficiency. The transmitters will operate with the new Ampegon control system to optimize DRM performance, an important factor in the growing Indian DRM market.

 

All India Radio has selected Ampegon as supplier because of the expertise and the reliability of their transmitters well known since decades. AIR is already using many different Ampegon AM/DRM radio transmitters which have been delivered between 1983 and 2012.

 

The transmitters will be manufactured in Turgi, Switzerland. Factory tests together with AIR engineers are planned for January and shipment for February 2014. Thereafter AIR will install the transmitters at a site near New Delhi. Commissioning together with an Ampegon engineer will start in August 2014. The new transmitters are expected to be on air in October 2014.

 

They will be partially used for DRM digital broadcasting and partially for analogue transmission. Furthermore AIR has plans to upgrade 36 of the existing AM mediumwave and 4 of the existing AM shortwave transmitters for DRM digital broadcasting. 

 

AIR originates programming in 23 languages and 146 dialects. AIR operates 244 FM transmitters for coverage of 29.4% surface area and 41.6% of the population. AIR also operates mediumwave transmitters which cover 92% surface area and 99% of the population. Further AIR operates 48 shortwave transmitters. 21 of them are 500 kW or 250 kW shortwave transmitters and are used for external international services. 27 of them are 50 or 100 kW shortwave transmitters and are used for local services and for  coverage of neighboring countries.
