G'day All,

This may be off-topic for some, but I know there are many who are interested
in experimentation for its own sake.

I have done some experiments using the earth base antenna installation
regarding measuring the potential difference variations over time.

Go to my experimental web pages (see address below) and scroll down to
Telluric Currents.   I have some graphs of portions of about 30 hours of
data.   Of particular interest is the presence of a 4.5 second period
sinusoidal signal and a strange long-term period pulse train.    To better
appreciate the data I have converted and compressed the 30 hours of data
into a WAV file so that you "hear" the data instead of viewing.

Comments and explanations would be most welcome !!!
