DK8KW Longwave Information
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!
