This week, the BBC has confirmed that Radio 4 broadcasts on long wave will conclude tomorrow, June 27, 2026, with the complete closure of the long wave platform following on June 30. This decision brings to a close nearly a century of service on a technology that once provided essential national coverage across the United Kingdom and beyond. No programs will disappear as a result. All Radio 4 content continues without interruption on FM, DAB digital radio, the BBC Sounds app and website, smart speakers, and television platforms such as Freeview and satellite services. FM alone reaches 99.5% of UK households and serves as the primary alternative for most remaining long-wave listeners.
Long wave radio operates in the very low frequency portion of the spectrum, generally between 30 and 300 kHz. These signals possess wavelengths of one kilometer or more, which gives the band its name. The physics of propagation sets long-wave apart from higher-frequency services. During daylight hours, the signals travel as ground waves that follow the curvature of the Earth, delivering reliable reception over hundreds of kilometers from a single high-power transmitter. After sunset, the ionosphere becomes more reflective, allowing skywave propagation that can carry signals much farther, sometimes across entire continents under favorable conditions. This combination of daytime ground-wave stability and nighttime sky-wave extension made long wave ideal for national broadcasting services that needed consistent coverage in remote rural areas, mountainous regions, and at sea with relatively few transmitter sites.
For generations, the BBC used the 198 kHz long wave frequency, primarily from the historic Droitwich transmitting station in Worcestershire, with supporting facilities at Burghead and Westerglen in Scotland. The service began in the 1920s with early weather and farming bulletins from Daventry and later became closely associated with Radio 4 after the station assumed the long wave allocation in 1978. The distinctive audio characteristics of long wave—lower fidelity but exceptional range and resilience to certain forms of interference—gave it a unique place in British radio culture. Many listeners valued its simplicity and dependability, especially those in areas where FM reception could be patchy or during severe weather when other signals might falter.
One of the most culturally significant elements tied to the long wave frequency was the Shipping Forecast. First broadcast in the 1920s and later moved to Radio 4 to preserve its long wave slot, the forecast delivered concise meteorological information for sea areas surrounding the British Isles. Its placement on long wave ensured mariners could receive it reliably far offshore at any time of day or night. Although the number of dedicated long-wave slots had already been reduced in 2024, the forecast’s heritage on the platform contributed to its enduring status as a national institution. It will continue on the standard Radio 4 schedule available through FM, DAB, and digital platforms.
The closure follows years of preparation. The BBC first signaled its intention to wind down long wave in 2022 and ended separate long wave scheduling in March 2024. The infrastructure, owned and operated by a third party, has reached the end of its operational life. Replacing aging equipment and maintaining the service for the very small remaining audience would require major capital investment that the corporation considers disproportionate. Digital listening has grown dramatically over the past decade, and the majority of UK radio consumption now occurs on DAB, online, or through connected devices. These platforms offer higher audio quality, additional data services, on-demand listening, and greater energy efficiency.
The BBC has supported the transition with repeated on-air messages, dedicated help pages on its website, and telephone assistance through the BBC Helpdesk. Particular efforts have focused on vulnerable listeners, including older people who may rely on simple analog radios. Practical guidance covers retuning existing sets to FM or DAB, using free BBC Sounds apps on smartphones or tablets, and connecting smart speakers. The organization has also worked with groups representing older and disabled audiences to ensure sensitive, timely support reaches those who need it most.
Long wave is not classified as critical national infrastructure. While the Shipping Forecast provided valuable supplementary information to seafarers, primary maritime safety communications rely on dedicated systems managed by the Maritime and Coastguard Agency. The BBC’s investment priorities now center on digital and FM platforms that deliver resilient coverage to the widest possible audience while allowing resources to support new content and technologies.
The end of long-wave transmissions represents a broader evolution in public service broadcasting. The technology that once enabled a single transmitter to serve an entire nation with reliable signals has given way to more efficient, higher-quality digital alternatives that also support interactivity and personalization. Many listeners will feel a sense of nostalgia for the familiar hum and reach of 198 kilohertz, yet the core mission of Radio 4—to inform, educate, and entertain—remains unchanged across its modern distribution channels. As the final long wave broadcasts air in the coming days, the service transitions fully into the digital age while preserving access for every audience that wishes to continue listening.
