The station broadcasts in the Île-de-France: in Paris on 89.9 FM where it can almost be heard in the whole region, and the French Riviera, with frequencies in Nice and Cannes.

[1] TSF, the acronym of the station, stands for Télégraphie Sans Fil and means "Wireless Telegraphy", an archaic French term for "radio".

[6] In September 2008 the station announced to change its name again to "TSF Jazz" (without reference to the Parisian 89.9 frequency) and adopted a much more simple logo along with a new slogan, with the main objective to cover France nationally.

[7] On 4 December 2008, TSF Jazz started broadcasting on its seventh frequency in Laval; around 100,000 people in the area could receive the station.

[8] On 26 May 2009, the CSA selected the radio station to broadcast digitally in Marseille, Nice and Paris.
