There is a copy of G0AKN's paper summarising his experiments on my website.

If I recall correctly, G0AKN (now SK) tried audio frequencies as well as 73 and 136 kHz.  G8DSU, who monitors this list, may have more information.  An article by G0AKN on this subject appeared in the Jan-Feb.1999  issue of the AMRAD newsletter.  More information may be found by searching online for G0AKN.

Most cave radio work takes place on 87kHz USB although we have sometimes used frequencies as low as 27kHz.  The maximum range we have achieved with a 4 W transmitter is about 2 1/2 kilometres.
