      Excellent work!
      One could have input direct to a "sound card" through a band pass filter
      I have uploaded a photo of the Alexanderson Alternator used
      for these transmissions. It can be found in the Photos section.

      > A successful reception of SAQ's transmission in Grimeton at 24-12-2012 has been made in Athens, Greece. A 5 meter vertical wire was used as the antenna , feeding a VLF upconverter. The upconverter's output was then fed to an SDR (built around the UHFSDR and USB2SDR boards). The XVTR capabilities in PowerSDR were used so as to display the correct frequency.
