LU28 DEFINITELY OFF THE AIR ON AM
LU28 RADIO TUYÚ, an AM station that operated on the 1540 kHz frequency from the town and district of General Madariaga, Province of Buenos Aires, apparently belongs to the group of stations that have ceased AM broadcasts, as its transmitter has been dismantled and the station is now reportedly only audible via its FM channel at 92.5 MHz (LRM403, FM TUYU) – a circumstance we have not yet confirmed – and through its social media channels. In its early days, the station served as a bridge between the countryside and the city, filling the gap left by the lack of telephone lines that would have allowed contact between the farmhand in the fields and the employer living at home with his family. Thus began the catchphrase: “Radio Servicio LU28. In the countryside, in the city, LU28 at the service of the community.” The station went on the air on November 7, 1970 , having been granted the license to operate on the 1540 kHz frequency. Over time, it became a major media outlet on Argentina’s Atlantic Coast, with a studio located in the city of Pinamar. Thanks to the initiative of one of its most renowned General Directors, Mr. Hugo Killamet, it eventually merged with the local channel “Canal 4 CAVIMAD,” which was later shut down due to the 2001 crisis. RADIO TUYÚ’s studios were located at 366 San Martín Avenue, while the AM transmission plant was situated on a plot of land at the intersection of Pte. Carlos Pellegrini and Calle 14 (Coordinates: 37°01’03.1“S, 57°07’28.5”W), where there was a 42-meter-high mast and a transmitter authorized to broadcast under Category VII, equivalent to a power of 0.25 kW (Daytime/Nighttime).
Upon checking the location of said antenna, it was observed that it had been dismantled. This development may be explained by the fact that, for several years now, LU28 has ceased broadcasting on its traditional AM frequency, initially due to technical issues that affected the regularity of its broadcasts, compounded by a lack of financial resources to resolve them, and possibly also due to legal issues related to its license, given that there is no regulatory record indicating that the regulatory authority has renewed or extended the validity period of its license.
