The Shortwave Transmitters of SPT, AIR, Bangalore
Shortwave broadcasting, a testament to technological innovation, offers a unique and cost-effective method to reach global audiences over vast distances. Leveraging the power of radio waves, it has been a cornerstone of international communication for decades. Recognizing the enduring potential of this medium, the Government of India initiated a project to strengthen its external services by establishing a state-of-the-art shortwave transmission facility in Bangalore.
A Strategic Location
Bangalore, a city renowned for its technological prowess, was strategically chosen as the site for this ambitious project. Its favorable geographical location and robust infrastructure made it an ideal choice for setting up a high-power shortwave transmission complex. The facility, operated by All India Radio (AIR), houses a network of powerful transmitters capable of broadcasting Indian perspectives and cultural heritage to a global audience.
The heart of the Bangalore complex lies in its six 500-kilowatt shortwave transmitters. These cutting-edge devices, employing Pulse Step Modulation (PSM) technology, are among the most powerful in the world. Their advanced design and digital control systems enable efficient and reliable operation, ensuring seamless transmission of high-quality audio signals.
The complex boasts an impressive aerial system comprising 36 multi-band curtain antennas. These antennas, strategically positioned on towering structures, can be electronically steered to target specific regions of the globe. This flexibility allows for precise beamforming, optimizing signal strength and minimizing interference.
Broadcasting for the World
All India Radio's External Services Division (ESD) utilizes the Bangalore facility to broadcast a diverse range of programs in 23 languages. These programs, tailored to specific target audiences, aim to:
Promote India's perspective on global affairs. By providing insightful analysis and commentary on current events, ESD seeks to foster understanding and cooperation among nations. Strengthen cultural ties. Through the dissemination of Indian music, literature, and traditions, ESD aims to bridge cultural divides and promote intercultural exchange. By providing news, educational programs, and public service announcements, ESD empowers listeners and contributes to social development.
A Legacy of Innovation
The shortwave transmitters at SPT, AIR, Bangalore represent a significant milestone in India's broadcasting history. They stand as a testament to the country's commitment to global communication and cultural exchange. As technology continues to evolve, this facility will undoubtedly play a vital role in shaping India's international image and strengthening its connections with the world.
But unfortunately recently they stopped to broadcast lot of languages due to the budget cut.
