- TDF_time_signal abstract "TDF is a time signal controlled by the LNE–SYRTE and broadcast by TéléDiffusion de France from the Allouis longwave transmitter at 162 kHz, with a power of 2 MW.It is also known as FI or France Inter because the transmitter primarily broadcasts the France Inter AM signal.In 1980, the first atomic clock was installed to regulate the carrier frequency.The current time signal is generated by an extremely accurate caesium fountain atomic clock and phase-modulated on the 162 kHz carrier in a way that is inaudible when listening to the France Inter signal using a normal AM receivers. It requires a more complex receiver than the popular DCF77 service, but the much more powerful transmitter (40 to 80 times DCF77's 50 kW) give it a much greater range of 3500 km.The signal is almost continuous but there is a regularly scheduled interruption for maintenance from 01:00 to 05:00 every Tuesday.".
