Check out my web site at  http://www.caving.btinternet.co.uk
There is a little about cave radio beacons for radio location and depth
finding.
Also there is a brief explanation of a positioning system I have called SNAP
which is short for
Speliogical Navigation And Positioning, and a brief report on 73Khz SSTV
from underground.

Helllo from Iowa, USA.

I seem to recall an earlier thread about Cave Radio on this reflector.

I made note of this URL: http://www.bcra.org.uk/sig/creg.html

Are there any more out there?
