My VLF grabber has been reactivated at http://www.df6nm.de/vlf/vlfgrabber.htm . I have modified the common mode isolation scheme at the antenna input, hoping to make reception a little less susceptible to local interference.
Spectrum data from the 63 uHz instance are periodically saved for possible a-posteriori analysis of slow EbNaut or Op-4H signals. In the left half of the spectrogram, the 8270.005 Hz carrier from Uwe's Feb/Mar 2014 TA-attempt is still visible.
Best 73,
Markus (DF6NM)
