Nothing seen here on a 2nd PC receiving the raw signal from VLF6 with a 
higher resolution spectrogram, but that's no surprise with the recent 
QRN / thunderstorm activity.
Unfortunately the low-power netbook that streams VLF6 to Paul's server 
is too slow for running a second SL instance. And for the VLF audio 
stream, I don't want to turn on the noiseblanker before the Vorbis 
encoder, because this would make listening to the stream very unpleasant.
But keep fingers crossed, maybe the 191 km wavelength signal gets close 
to the '2 lambda' distance..

Cheers,
   Wolf .

            Hello ULF friends,<br>
            <br>
            I just opened up a new band by starting some activity on <u><b>1570
                Hz</b> </u>! It is the <b><u>191 km</u></b> band! :-)<br>
            <br>
            Since 8 UTC a carrier is running at 1570.01 Hz. Soon the
            first trace
            will appear on a spectrogram from my tree which is in 3.5 km
            distance
            from the transmitter.<br>
            See the developing trace at <a moz-do-not-send="true"
              class="moz-txt-link-freetext"
href="http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html">http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html</a><br>
            The spectrogram scrolls with 10 minutes/pixel.<br>
            The carrier will stay on the air for 2.5 hours. It is just a
            first
            test. So far the antenna current is just 27 mA but tonite
            i'll try to
            reach the target level of 58 mA which means 12 kV again
            acros the
            special iron cored coil. This will mean about 120 nW ERP
            then.<br>
            <br>
            DL0AO is already watching the band. I hope to be received by
            Paul and
            at the reomte site of DL4YHF. I'm not planning to do /p RX
            experiments
            on that band, just focusing on these 3 RX stations.<br>
