I happened to notice this morning that my old "Conrad" DCF77 wall clock had not changed to summertime and indicated "no lock" even though the pulses looked good to my eye.
After about I minute I noticed that the first 14 pulses were no longer uniform '0' bits, and a bit of googleing turned up the interesting news that there is now weather information embedded in the first 14 bits. http://www.meteotime.com/web/de/System/Default.aspx 0 1 2 3 4 5 012345678901234567890123456789012345678901234567890123456789 -#--#---#--####--#--#--#--#--#--##-#---#-###-##---###-----# --#----#--####---#--##-#--#-##--##-#---#-###-##---###-----# -##--#-#-##-#----#--#-##--#-##--##-#---#-###-##---###-----# --###-##-##-#----#--####--#--#--##-#---#-###-##---###-----# ---#-----#-#-#---#--#---#-#--#--##-#---#-###-##---###-----# -#------#--#-##--#--##--#-#-##--##-#---#-###-##---###-----# -#-----#--##-#---#--#----##--#--##-#---#-###-##---###-----# --#--#----#####--#--##---##-##--##-#---#-###-##---###-----# ^^^^^^^^^^^^^^ Obviously, my clock is so old that it was writte for the older "if you see any of these bits, the transmitter has problems" signal spec. Anyone know the encoding of the weather info ? I wonder if they use the minute bits to designate regions to save bits ?
