Excellent question. From the DCF "homepage", I figure the 
phasemodulation is still experimental, unsupported. (but here to stay).

Are there any experiences/experiments with the reception/decoding of the 
phase data ? Given the low frequency, maybe even a low-cost PLL/VCO 
(ne567 ?) could do the trick, IMHO. The LW-frontend could be provided
by a modified DCF alarmclock, which can be bought for 10-20 eur here.
