DCF39 reception in the United States!

Dick, WA3USG and Bob, K3DJC have send me a WAV file with a recording of what is suspected to be DCF39 on 138.830 kHz. As can be seen from the attached Spectrogram (V 5.1.6), the pattern of this transmission follows exactly the data-burst pattern of the DFC39 transmitter (around 13 seconds carrier, data-burst about 1/2 second). I have marked the data-bursts in red. Congrats on the reception of this high kilowatt receiver, now we need to go for the next challange a couple of dozens dB lower!
