I was reading an article while I was looking around for radio projects
for long wave, and I came across this article about a teenager who was
said to be an inventor of something that people thought it could not be
done. He used a huge loop antenna with a 2 way LF radio, probably not
FCC approved or licensed, not part 15 to transmit a text signal deep in
the holes of the Earth at 1000 feet. Main thing is that how did he get
rights to text on LF when he is not licensed by the FCC, is he using the
160 kHz to 190 kHz band to send the signals back and forth? Or is he
using VLF communications? I thought this might interest some long wave
radio hobbyists and techs, and engineers. There is no project or
schematic for this, so this maybe something he probably is used a dot
matrix display to do it. Is there a text data project out there that
uses a lowfers transmitter? Lets just hope he gets his FCC experimenters
license and patents applied. Now I feel that there is more to be
discovered today in digital LW technology.
