STL By Ground
Posted on December 3, 2012
To define terms, we remind that “STL” means “Studio-to-Transmitter-Link”, an electronic pathway by which a station’s audio is transported from the studio to the transmitter.

Many methods have been discussed, but narrow down now to one that hasn’t been considered.
As we heard from MICRO1700 there have been experiments to send audio directly through the ground, by driving ground rods with the output of an audio amplifier, then retrieving the signal somewhere else by a second set of ground rods connected to the input of an audio amplifier.
While in the electronic state, before being converted by a loudspeaker into acoustic energy, audio actually is an RF (radio frequency) energy in the VLF band (Very Low Frequency) essentially below the LW band (long wave).
With a very powerful sending amplifier, 100Watts and more, it might be possible to go miles.
Go ahead, shoot my theory. Make your day.
