I can't help you with Scandinavia, but last week, I did add the VLF band to the WebSDR at the University of Twente in the Netherlands. The antenna is the same 80 m long wire that we use also on the other bands. Unfortunately, the signal-to-noise ratio with this antenna seems to be worse than optimal. The receiver is at http://websdr.ewi.utwente.nl:8901/ In light of your plans to perhaps soon try a transmission again, I've now quickly added a grabber for 8.97 kHz. It's at http://websdr.ewi.utwente.nl:8901/grabber.html 73, Pieter-Tjerk, PA3FWM
