Stefan DK7FC is always experimenting at VLF and ULF. Recently he has been radiating a signal at 2.97kHz and he has detected his own signal at 9km. This is not earth mode. He is trying to get reports from much further.

Thanks for your blog Roger.
73 de DK7FC
PS: Meanwhile the 17 km far field distance was crossed, see the emails on the reflector :-)
Stefan - good luck with your experiments. I have amended the 2016 news in the Sub 9kHz Amateur Radio website. See https://sites.google.com/site/sub9khz/vlf-news-2016 . I shall try to add news of your work to my blog and the Sub 9kHz website. You are truly at the "sharp end" of amateur radio - well done.
