Hi Bob:

Ok...now I understand the scenario / set-up.

I've got a few more Qs.

1) What was the source of the audio waves? A piezocrystal excited by a waveform generator which physically pressed the crystal?

BOB: We assumed and hypo'ed. We were never sure where it was coming from, but the experiments took place at 3500 feet in the Kettle Range, heavily forested, very few humans...

We did have a local friend, Andy X, who was what I called a crystal finder..Andy could hone in on crystal deep in the ground using his head only. He never missed and the nodes were generally 6-10 feet underground. He was a very eccentric person....still alive but had an accident in which he was unconscious for a week and now does not know what crystal we are talking about.

+ So the experiment would start after Andy X would dig up some crystals in the ground ? Or there was also an ambient level all the time that would come and go...?

What would you do to vary anything Or would there just be natural variation happening (like the frequency changing...)

How would you go about replicating the experiment. Was your goal to see how many could detect the ULF/VLF waves ?
