I have a suggestion:
- try with a short wire, note results on scope.
- try with a very long wire, compare results on scope with short wire
results.
If it matches, hurray!

external connections be?
Roy, I will do when I get the cable in that I plan on using for
this. By chance, can you give me a hint as to what sort of good and
bad things I should be looking for?
Right now, my technique on the scope is more or less, if I see two
horizontal lines - spaced apart at the voltage and duration I think
they should be - I am happy.
