At the moment, its really DCF39 transmitting there on 138.83 kHz. I wrote a crude FSK demodulator + decoder for it (based on Klaus Betkes info), and found it still sends a plain ASCII string "DCF39" occasionally.
I also checked the 200 baud data from DCF39 some time ago and found that
the packet format was surprisingly similar to the "M-BUS" format used for remote
reading from water, heat and energy meters. Same header, same start & stop
characters etc.
