ULF Amateur Experiments

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.

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.
