In France this frequency is used by low power transmitters along the motorways/highways to provide traffic information services to drivers. Several networks (e.g. Radio Vinci Autoroutes, Autoroute Info, Sanef 107,7) air their programme on FM 107.7 by low power transmitters, which can only be received on the highways and in a short distance away from the highway. These 3 stations are all well-known for their frequent traffic reports (every 15'), although the music accounts for 90% of their daily programming, with 10 songs an hour.
2 Shortwave uses a combination of AM, VSB, USB and LSB, with some NBFM and CW/morse code (in the case of time signal stations) as well as numerous frequencies, depending on the time of day/night, season, and solar activity level. A reasonably full list from 16 kHz to 27MHz can be found at 
3 Regions 1 and 3 also use Region 2's frequencies as well, with 50 to 100 kHz spacing.
