Hi Christer, Do have a go! I for one am all ears. IK1ODO's web page at http://space.tin.it/scienza/rromero/ has some useful pointers to other articles, where VLF antennas are described. Best of luck
You might also check out "cave radio" and spelunkers (Sp.?) pages. I have read articles in the past about these frequencies. One thing that comes quickly to mind is direct loop to loop transmission.
100%. I meant to be brainstorming more than advising. Doc. The problem with loop to loop operation at these frequencies is that is subject to the inverse cube law of magnetic induction rather than an
Hi, I think that I was the first to send PSK31 at 1Khz through the Earth..... My interest was in experimenting with Ohmic "Earth Current" communications as distinct from Magnetic induction or Electro
G'day All, Here in VK-land although the regulations say there are no allocations below 10kHz and it APPEARS that there would be no restrictions, there is a document which sets out the bands for the C
