Talk:TDF time signal

From Wikipedia, the free encyclopedia
Jump to: navigation, search

There is, AFAIK, no organization called "Télé Distribution Française", or even "Télé Diffusion de France" (although TDF – Télédiffusion de France – does exist). Would those who know more about the subject of this article care to make the necessary corrections to its introduction and, especially, its title (the article being, in any case, about the time signal service itself rather than its provider)? -- Picapica (talk) 15:53, 13 October 2009 (UTC)

I've removed the reference to Laboratoire primaire du temps et des frequences.
I've also removed the reference to Centre National d'Etudes des Télécommunications (folded into France Telecom R&D a.k.a. Orange Labs, according to the WP page).
It's annoying that TDF doesn't appear to have an official name, let alone an official webpage giving the spec. [3] calls it FI and France Inter. I suspect TDF is the callsign. ⇌Elektron 00:40, 26 June 2012 (UTC)


I've picked "TDF time signal" because the most common name is "TDF" and "TDF (time signal)" suggests that TDF is the official name of the signal (I can't find any page giving the time signal itself a name) or the callsign of the station ( calls it "France Inter" with no callsign; fr:Émetteur d'Allouis does not give a callsign). NIST calls the "signal" TDF but the document does not mention "callsign". I don't have the International Frequency List handy.

Perhaps it should be merged with Allouis longwave transmitter to more closely match, except the time signal is not the station's primary purpose (unlike the other time signal pages). ⇌Elektron 01:22, 26 June 2012 (UTC)

Coordinate error[edit]


The following coordinate fixes are needed for 47° 10′ 10.5″ N, 2° 12′ 16.5″ E 47.169583, 2.204583

Your coordinates differ only slightly from the ones in the article, and both sets are too precise, anyway. I've changed the coordinates to four decimal places, which is plenty precise for something of this sort. See WP:GEO#Precision guidelines. Deor (talk) 15:28, 6 December 2013 (UTC)
