A new chapter has opened in Kenya’s broadcasting space after the Communications Authority of Kenya switched on the country’s first Digital Sound Broadcasting pilot signal in Nairobi during this year’s World Radio Day celebrations.
The development signals the beginning of digital terrestrial radio transmission in a country where radio continues to dominate the media scene.
With coverage reaching nearly 98 per cent of households and more than 300 licensed stations on air, radio remains a key source of news, education and entertainment across the country.
Even so, the traditional FM platform has been operating under growing strain. The VHF Band II spectrum between 87.5 and 108.0 MHz is already fully allocated in large urban centres.
This congestion has limited opportunities for new broadcasters while also leading to overlapping signals and uneven sound clarity.
“The move toward digital transmission reflects a strategic response to these pressures, positioning Kenya to modernise its broadcasting infrastructure while safeguarding universal access, the statement released on Friday, February 13, 2026, read in part.
To address the capacity challenge, the Authority in 2023 crafted a detailed framework to guide the shift to Digital Sound Broadcasting. The policy focuses on Digital Audio Broadcasting within VHF Band III covering 174 to 230 MHz, as well as Digital Radio Mondiale operating in the HF band at 30 MHz.
The framework was shaped through consultations with broadcasters, signal carriers, equipment suppliers, public agencies and industry bodies to ensure that the transition reflects sector needs and market realities.
Implementation gathered pace in 2025 when the regulator approved Signet Signal Distributors Ltd and Mast Rental Services Ltd to roll out pilot DSB networks. In January 2026, Mast Rental Services became the first to activate a DAB+ trial system, which is currently transmitting 14 radio stations within Nairobi and nearby areas.
“The activation of the DSB signal marks Kenya’s first operational step into digital terrestrial radio broadcasting. The transition to digital radio is expected to reshape the broadcasting value chain,” the authority stated.
Under the new structure, programme creators and transmission operators take on separate roles. Broadcasters will concentrate on developing content, while licensed network providers manage signal infrastructure. Through digital multiplexing, several stations can be transmitted on a single frequency block, cutting distribution expenses and improving spectrum use.
The arrangement is expected to open doors for new players by lowering operating costs and easing entry requirements. Capacity has also been set aside for community stations at nominal carriage fees, supporting diversity and ensuring that smaller voices are not locked out of the digital space.
For audiences, the change promises improved listening quality and more choice. Digital broadcasting reduces interference and offers cleaner audio output compared to crowded analogue bands.
“The platform will enable greater content diversity, including thematic, regional, and digital-only stations serving specific communities,” CA said.
Beyond improved sound, digital systems can carry extra information such as programme details and station data, adding a new layer to the listening experience.
The Authority has maintained that the digital rollout will run alongside existing FM services. There is no set date for shutting down analogue broadcasting, allowing listeners to continue accessing their favourite stations as the country gradually adopts digital receivers.
The expansion plan will be phased, starting with the Mombasa–Nairobi–Kisumu corridor and other high population zones. During a 12 month pilot phase, the regulator will evaluate signal reach, service standards, receiver prices and public awareness levels before making further decisions.
By launching the Nairobi trial, Kenya joins other countries exploring digital radio technology as the next step in the evolution of broadcasting.
The Authority has also indicated it will work closely with regional partners to harmonise technical standards, encourage cross border coordination and attract investment into the sector.
The start of the Digital Sound Broadcasting pilot therefore lays the groundwork for a broader transformation, aimed at delivering a more inclusive, cost effective and modern radio environment while keeping current services intact during the transition.
