About Radio Seefunk

Radio Seefunk

Radio Seefunk is one of southern Germany's most successful private local stations, broadcasting from Konstanz on Lake Constance to the Bodensee region, Upper Swabia and the High Rhine. Founded in 1987 as seefunk radio bodensee, the station evolved from a city broadcaster for Konstanz into a cross-border regional brand — renamed Das Neue Radio Seefunk in September 2018 and back to Radio Seefunk on 6 August 2025. The ma 2019 Audio I survey credited it with 168,000 daily listeners and the largest audience growth of any German station that year. Its shareholders include the rt1.media group, the Friedrichshafen local broadcaster, Meier + Cie of Schaffhausen and the Bodan AG of Kreuzlingen — a German-Swiss ownership reflecting its cross-border audience.

Overview

Radio Seefunk is a local radio with a strong editorial focus on local information. The founding programme targeted "everyone from 8 to 88", but market experience — not only in Konstanz — taught the station that a sharp target-group definition was needed; the over-30 audience was chosen and an oldies format offered under the name "seefunk radio – der oldiesender". A further format modification under the renamed Radio Seefunk sharply increased target-group exploitation. The station is privately owned and advertising-financed, with reception on FM across the Bodensee–Oberschwaben–Hochrhein area, on DAB+ and as a worldwide webstream, plus significant listenership in Switzerland.

History

Today's Radio Seefunk was founded in 1987 as seefunk radio bodensee and went on air on 1 September 1987 on 101.8 MHz with just 100 watts from Konstanz — a pure city station for the university town. Over time further frequencies were added in southern Baden-Württemberg. The target-group refinement to the over-30s brought the "oldiesender" branding, and a later music-format modification under the Radio Seefunk name drove strong audience growth. The ma 2017 Radio II survey measured around 147,000 daily listeners in Germany and 34,300 in Switzerland — making it one of southern Germany's most successful private local stations. In early September 2018 the station renamed itself Das Neue Radio Seefunk; the ma 2019 Audio I survey then credited it with 168,000 daily listeners and, with hourly net reach up by two-thirds (from 21,000 to 35,000 listeners Monday–Friday on average), the largest listener growth of any German station. On 6 August 2025 the station was renamed Radio Seefunk once more.

Programming

The programme centres on local editorial content: regional news, service, weather and traffic for the Lake Constance region, Upper Swabia and the High Rhine, framed by a music format tailored to the over-30 target group. The cross-border dimension is built into the journalism — with Swiss shareholders and tens of thousands of Swiss listeners, the station covers the German-Swiss border region as a single lived space. Local events and regional identity round out the schedule.

Coverage & Audience

Radio Seefunk broadcasts on FM across the region: Konstanz 101.8 MHz, Isny 103.9, Friedrichshafen 99.3, Sigmaringen 104.2, Pfullendorf 100.1, Überlingen 96.4, Ravensburg 102.6 and Singen 105.3 in the Bodensee/Oberschwaben area, plus Rheinfelden 103.1, Wannenberg/Klettgau 107.0, Laufenburg 102.4, Lörrach 104.3, Waldshut-Tiengen 105.4 and Schopfheim 101.9 on the High Rhine.

The ma 2019 Audio I survey credited the station with 168,000 daily listeners in Germany, with the ma 2017 panel adding 34,300 daily listeners in Switzerland. Its official domain was not independently load-verified during research, so no website is asserted here.

Ownership

The shareholders are the rt1.media group of Augsburg, the Friedrichshafener Lokalrundfunkgesellschaft of Tettnang, Meier + Cie of Schaffhausen (Switzerland), the Radio-Kombi CP Media Südwest GmbH & Co. KG of Stuttgart and the Bodan AG of Kreuzlingen (Switzerland). The German-Swiss shareholder mix mirrors the station's cross-border audience and its editorial focus on the border region.

Digital Presence

Radio Seefunk operates a website and livestream alongside apps and social media channels, extending its local journalism and music programme to listeners beyond the FM footprint — including the Swiss audience that forms a significant part of its reach. The digital channels carry the live programme, regional news and event content for the Lake Constance region, serving the cross-border community that defines the station's identity.

seefunk radio bodensee: The 1987 Launch

Today's Radio Seefunk was founded in 1987 as "seefunk radio bodensee" and went on air on 1 September 1987 on 101.8 MHz with 100 watts in Konstanz — a pure city station for the university town on the lake. The founding programme targeted "alle von 8 bis 88" (everyone from 8 to 88). Over time more frequencies in southern Baden-Württemberg were added, and the station learned — not only in Konstanz — that a clear target-group definition was needed to succeed: for market reasons the 30+ target group was chosen, with an oldie format under the name "seefunk radio – der oldiesender". The programme name was later changed to Radio Seefunk and the music format modified again, sharply increasing target-group penetration.

The Biggest Listener Growth in Germany

The ma 2017 Radio II showed around 147,000 daily listeners in Germany and 34,300 in Switzerland for the then Radio Seefunk RSF — already one of the most successful private local stations in southern Germany. In early September 2018 the station was renamed "Das Neue Radio Seefunk", and the ma 2019 Audio I (published 27 March 2019) showed 168,000 daily listeners — with the hourly net reach growing by two thirds (from 21,000 to 35,000 listeners on average, Monday–Friday), making it the station with the biggest listener growth nationwide in that survey. On 6 August 2025 the station was renamed back to Radio Seefunk.

A Three-Country Shareholder Base

The shareholders reflect the station's Lake Constance identity: the rt1.media group (Augsburg), the Friedrichshafener Lokalrundfunkgesellschaft (Tettnang), Meier + Cie (Schaffhausen, Switzerland), the Radio-Kombi CP Media Südwest (Stuttgart) and Bodan AG (Kreuzlingen, Switzerland) — German and Swiss owners for a German-Swiss audience.

From a 100-Watt City Station to the Lake Region's Radio

Today's Radio Seefunk was founded in 1987 as seefunk radio bodensee; the launch was on 1 September 1987 on 101.8 MHz with just 100 watts in Konstanz — a pure city station for the university city. Over time further frequencies in southern Baden-Württemberg were added. The founding programme targeted "everyone from 8 to 88"; later the station — like others — realised it needed a clear target-group definition, and chose the over-30s, offering them an oldies format. The name changed to seefunk radio – der oldiesender, then to Radio Seefunk with the music format modified again — and target-group exploitation rose sharply. The ma 2017 Radio II found around 147,000 listeners daily in Germany and 34,300 in Switzerland, making Radio Seefunk one of the most successful private local stations in southern Germany. In early September 2018 the station was renamed Das Neue Radio Seefunk; the ma 2019 Audio I then counted 168,000 daily listeners — with hourly net reach up by two thirds (from 21,000 to 35,000, Monday–Friday), the biggest listener growth of any German station. On 6 August 2025 it was renamed Radio Seefunk again.
