"Reg Edwards"
Some years back I buried a 30 metre (60-feet) auminium wire
one spade depth in my back garden.
As a counterpoise, something essential to tune it against, I erected a
wire in the form of an inverted-L. This was about 30 feet high and
overall length about 140 feet.

I think a record of these buried antenna experiments should be kept
for posterity, alongside the famous biblical work of B,L & E.
____________

So you loaded your tx into an antenna system consisting of a 140 foot
inverted L, 30 feet above ground with a buried ground radial 99 feet long.
What is so unusual about that? Certainly not a venture of biblical
proportions, IMO.

Perhaps you haven't flipped enough of your calendar pages?
