Radio, one of the most deep-rooted tools of traditional media, has evolved from being just a medium into a multi-layered audio ecosystem with the widespread adoption of the internet and digital technologies. In an event held as part of NETlab, our guest, radio broadcaster and audio producer Yiğit Karaca Pehlivanlı, addressed this transformation—stretching from the historical function of radio to today's digital broadcasting—through both its technical infrastructure and his personal experience. This transformation represents not just a technological renewal, but a redefinition of how audio is produced, distributed, and consumed.

The Magic of Radio: A Personal Bond Formed Over Frequencies

Despite being a non-visual medium by nature, radio offers an incredibly powerful experience in terms of the relationship it builds with the listener. At the heart of this experience lies the sense of personalized communication created by sound. A broadcast reaching millions is often perceived by the listener as an individual address.

In the pre-internet era, this impact was even more pronounced. Music discovery took place largely through the radio, as access to alternative sources remained quite limited. In the years when TRT was the only channel, accessing different genres of music was often impossible. At that point, international radio stations broadcasting over shortwave served as an alternative window for listeners.

In this sense, radio was not merely a tool for entertainment; it was a mechanism for discovery and guidance. The listener got to know both music and the world through the perspective offered by the radio.

Alternative Broadcasting Areas: University and Pirate Radios

Not only corporate broadcasting but also alternative production spaces have been decisive in the evolution of radio. University radios, in particular, are among the most significant components of this field.

College radios, which originated in the United States from the information-sharing needs of agricultural faculties, transformed over time into spaces where youth culture was produced. In Türkiye, examples such as Radio METU (Radyo ODTÜ), Radio Bilkent, and Radio İLEF (https://radyoilef.ankara.edu.tr/) have created important experimental areas where broadcasting is learned through practice.

Furthermore, the pirate radio culture that emerged in the UK during the 1960s played a critical role in the democratization of broadcasting. Through offshore broadcasts from the sea, music genres and alternative ideas that remained outside the mainstream entered circulation. This structure demonstrates that radio is not merely a technical tool but also an arena for cultural struggle.

The Limits of Frequency: Technical Issues and Lack of Regulation

Radio broadcasting essentially operates over frequencies, and this structure brings certain technical limitations. In an analog system, each broadcaster must remain within a specific frequency range. When this limit is exceeded, broadcasts interfere with one another, creating noise and static in the system.

In Türkiye, this became a serious problem with the rapid multiplication of private radio stations in the 1990s. Due to a lack of regulation, broadcasters increased their transmitter power, frequencies began to overlap, and an environment of technical chaos ensued.

This process affected not only broadcast quality but also different communication systems. The uncontrolled use of frequencies created risks extending even to aviation communications. During the same period, the social reactions against the closure of radio stations clearly demonstrated the public importance of the media.

Digitalization: DAB and the New Infrastructure of Broadcasting

The limitations of analog systems have been one of the most significant factors accelerating the digitalization of radio. At this point, DAB (Digital Audio Broadcasting) technology stands out.

DAB technology does not just improve radio broadcasting technically; it also offers a new logic of broadcasting. The primary advantages of this system include the ability to broadcast multiple channels over the same frequency, increased audio quality, and the provision of additional data to the listener.

While widely used in Europe, this system has not yet reached a corporate infrastructure in Türkiye. The fact that digital frequency tenders have not been held causes this transformation to be delayed. Consequently, radio in Türkiye remains largely dependent on the analog frequency structure.

*The most well-known example, Radio Caroline, began broadcasting from the North Sea in 1964. It was banned in 1967 with the Marine Broadcasting Offences Act.
