1MHz then and similar 555 based modulation. I believe I used just a
simple squarewave oscillator, one of these 5V metal box jobs, and a

It worked very well (too powerful even) but I think the high frequency
would not go through soil much.
In hindsight I should have just hammered nails into the wall. Because
of Murphy's law it is certain any nail hammered into any wall will hit
a wire. Murphy is much stronger than dousing even.
Goes to show why politics and religion is forbidden on these lists for

in common after all. Best not to stray off topic really, and stay
friends respecting each other.
