Hey tnom I think you meant to say 1" tinned copper braid it just looks
like silver but it is not made of real silver.

It was silver

also I see a big problem with your tests is that they are secret tests
done by anonymous cbers who cannot be contacted or confirmed or
documented i.e no names since one or more of you are probably involved
with illegal operation etc.

Yes, they were top secret. The tests were documented on special self
destruct paper. The results were never suppose to fall into the hands
of common people like yourself.
