In 2001, the CSA assigned four new frequencies to Sud Radio in the regions Auvergne and Limousin (in Brive, Ussel, Mauriac and Puy-en-Velay).

[2][3] In 2008, Sud Radio moved its studios to Labège near Toulouse and inaugurated a permanent correspondent in Marseille.

A new transmitter allowed additional coverage in Marseille and Aix-en-Provence and made a potential audience of more than 1.3 million people.

In November 2010, the Conseil supérieur de l'audiovisuel (CSA) allowed Sud Radio transmit in Clermont-Ferrand and Limoges.

In January 2011, the CSA selected Sud Radio to transmit in Paris for the Parisian area and Île-de-France region on the frequency 99.9 FM; it began broadcasting on 10 August 2011.

In November 2012 exclusive negotiations with Marc Laufer (former CEO of NextRadioTV) got underway for the acquisition of the station.
