Since 1939, the town of Allouis has housed the central transmitter station for long and short wave broadcasts of French national radio France Inter. In 1944, retreating German troops destroyed its four-latticed mast antenna system.
On 19 October 1952 a new long wave transmitter with an output of 250 kW was put into service at Allouis. Transmitting power was increased to 600 kW in 1957, to 1,000 kW in 1974 and to 2,000 kW in 1981.
Since 1977 the Allouis transmitter also transmits standard time signals for AMDS.
The radio channel France Inter discontinued the longwave transmitting (162 kHz) end of 2016.
