Thanks for posting that, Justin, it was most interesting, and the
reference to Brooke Clarke's page, which I did not know.
It would be interesting to know what the analogue signal looks like, as
many pieces of electrical and electronic equipment can radiate
significantly on those frequencies. I expect you optimised the signal,
though, as you've mentioned it.
Are you sure the images are all correct? To me, your Fig 2 and Fig 3
images look identical, as do Fig 6 and Fig 7.
"Precision" - well, that depends, doesn't it? Perhaps more precise than a
very poor Internet connection? Better than no Internet connection at all!
Certainly not GPS level.
