I'm often thinking about the old VLF propagation graphs https://dl.dropboxusercontent.com/u/19882028/VLF/fig_02_25a.png (what was the original paper where it comes from?) which make more and more se
VLF, In the event that Paul can produce no decode of my aborted transmission, i'm announcing a new attempt for the same message, but this time in shorter daily repetitions that can be added coherentl
So far no decode Stefan. I thought we might have got away with missing 13% of the signal if there was a dB or two to spare. I'm trying one more run with some relaxed blanker settings because the nigh
VLF, The first transmission worked very well. The antenna current was stable at 225 mA during the whole transmission, despite the snowing. The QRN was very low. I decoded my own message from the tree

Hello Paul, Thanks, that's great, just 3 days of about 8 hours each, for a 20 character message. But what was the message? I need to know it so i can see it as a valid detection. The daily transmissi
Not too bad, got most of the day. I'll still be able to use it. The mailing list is quiet this weekend, has everyone gone away? Nobody but us running experiments? I'm thinking of having a little pla
Hi Paul, Good question. Maybe some kind of winter sleep? OK, just try if you can use the todays transmission. But it is uncertain if just the end is missed or the beginning or some symbols inbetween.
Yes I keep thinking about kites. It sounds like a lot of fun. I've had a powersled 36TT on order from Kiteworld (UK) since last May, for some reason they don't seem to be able to send one. I think th
