But what would that tell us about the soil conditions to, say, three
skin depths -- or even one? What conclusions could we draw from that
information?

====================================

None, except that you are nit-picking as usual.

And that B, L & E, all three of them, were floundering about in an
amateurish fashion.

Yet it had been well known to others for 35 years that soil
conductivity and permittivity had a profound effect on ground wave
propagation.

All they had demonstrated was that 113 radials was more than
sufficient for MF and low HF broadcast propagation which was what
everybody already knew.

And so the rounded-up, Marzipan the Magician, magic number of 120 got
stuck in the bibles. A typical American way of going about things. ;o)
