Hi Magnus TDF (?) France Inter ( Allouis ) is, I believe, a strictly frequency distribution station like Droitwich 198kHz (UK) carrier referenced to a rubidium and measured by the French national bureau I expect. Details of MSF and Droitwich are available from NPL http://www.npl.co.uk/science-technology/time-frequency/time/
MSF, HBG, and DCF77 transmit time code, whereas there is data on the MSF and Allois carriers it is not time-code. I think Droitwich carries a utility service a little like DCF39 Magdeburg but less wide ranging. I think Droitwich is 500kW but may reduce at night.
