| Earth-mode experiments in 2011 |
This was my earth-mode signal 4.5km away from home in 2011 at 1.095 kHz using Spectran software on the PC. Strictly speaking, I suppose this is ULF!
It is a long time since I have done any earth-mode experiments, but my health has got in the way. It would be good to do some more experiments.
