bigFM Owner Sues German Regulator Over Frozen FM Frequencies in the North
Audiotainment Südwest is taking the Hamburg/Schleswig-Holstein media authority to court for refusing to re-tender FM spectrum freed when a rival station went dark.
The dispute
Audiotainment Südwest has filed suit at the Schleswig administrative court after the regional media authority MA HSH rejected its re-tendering request on 26 March 2026. The disputed spectrum is a second statewide FM chain freed up when delta radio stopped broadcasting on FM (UKW) on 23 November 2025.
CEO Kai Fischer argues that free FM frequencies must not be blocked "at the expense of media diversity and competition." Audiotainment Südwest — which operates bigFM, ROCK FM, RPR1. and Radio Regenbogen — says the case raises constitutional broadcasting-freedom questions.
Why an FM fight is an ad-inventory fight
It is easy to file this under "regulatory arcana," but FM reach still underpins a large slice of German audio ad inventory. Who controls freed frequencies directly determines where advertisers can buy local radio, and how competitive that market is. A blocked frequency is, in effect, inventory that never comes to market.
Our read: the outcome is a bellwether. If the court forces a re-tender, it expands competition and audience-buying options in the north; if it upholds the block, incumbents are entrenched and choice narrows. Either way, this is about the supply and price of a resilient mass-reach channel, not just spectrum policy.
What audio buyers should watch
First, track the Schleswig ruling as a signal for FM-capacity policy nationally. How regulators handle frequencies freed by stations leaving FM will shape local-radio competition — and therefore pricing and availability — well beyond one region.
Second, do not over-index on any single audio route while the picture is unsettled. As some broadcasters exit FM and others fight to expand on it, spread audio budgets across broadcast radio, DAB, digital audio and podcasts so a regulatory decision in one lane does not dictate your reach.
Quick FAQ
What is bigFM's owner suing over?
Audiotainment Südwest is challenging the MA HSH regulator's refusal (26 March 2026) to re-tender a statewide FM chain freed when delta radio left FM in November 2025.
Why does it matter for advertisers?
FM reach underpins much of German audio ad inventory, so control of freed frequencies shapes where advertisers can buy local radio and how competitive it is.
What should audio buyers do?
Watch the Schleswig ruling as a national bellwether for FM policy and spread audio budgets across radio, DAB, digital audio and podcasts.
It's easy to dismiss an FM-frequency lawsuit as regulatory arcana, but this is really a fight over ad inventory. A blocked frequency is reach that never comes to market. Whichever way Schleswig rules, it sets the tone for local-radio competition — and therefore audio pricing — well beyond one region. — Daniel Nikolla, Founder of Merx Marketing
Who controls freed FM frequencies decides the supply and price of local-radio inventory — treat the Schleswig ruling as a national signal, and diversify your audio buy.
