Hi everyone, I just saw this and it came in with the last post about FM
DX.  I don't konw about the rest of you, but the lowest my equipment will
go in frequencies is 100 KHz on the F6A.

New 'underground radio' technology improves emergency
capabilities

New Mexico Business Weekly - 12:43 PM MDT Wednesday

Los Alamos National Laboratory says Vital Alert
Technologies Inc. has signed two exclusive license
agreements with the lab for Underground Radio™, a
technology that will provide two-way voice and text
capability known as Through-The-Earth-Communication™
for first responders, rescue and security teams,
underground miners and the public in critical
emergency situations.

Underground Radio, originally developed by LANL for
the Department of Energy, is being commercialized by
Vital Alert Technologies for use by emergency crews in
urban centers and by the mining industry.

Vital Alert is a wholly-owned subsidiary of Vital
Alert Communication Inc. Vital Alert develops pre- and
post-emergency, safety and rescue technology for the
urban and mining communications sectors.

"The new technology is a breakthrough in digital and
wireless communications," says Joe Miller, president
and CEO of Vital Alert, in a news release. "As a pre-
and post-emergency warning, evacuation and rescue
communication system, it solves radio frequency
failure problems and eliminates systems' downtime
complications in difficult environments such as
subways, tunnels, skyscrapers and mines. The new
technology will also greatly enhance the ability of
mining companies to protect their workers."

Underground Radio uses very low frequency (VLF)
electromagnetic radiation and digital audio
compression technologies to carry voice and text data.
The VLF signals also can transmit tracking and
location data for radio users in case they are unable
to respond.

"This is a technical solution to the problem of voice
communication in underground areas," said David
Reagor, the principal investigator of the Los Alamos
team that originally developed the technology. "It's
also inexpensive to build."

Underground Radio can be used to alert individuals of
underground conditions during blasts, fires or
collapses, or to locate trapped miners. The technology
was designed to provide convenient, portable
underground communication and a data link to robotic
machines.
