Optical NLOS work

One of my interests before my 2013 stroke was optical communications over the horizon - non line of sight (NLOS).

Although I briefly tried a few years ago, I was still too wobbly, so had to give up. Sadly, I still feel giddy when on my feet, so further optical experiments are on hold for the time being. Others have continued the work and one thing worth trying is using infra-red, which many say is better for NLOS than red LEDs.

At some point I do hope my health improves so that I can resume these tests. Test gear is simple (easier than microwaves) and this really pushes the boundaries - true experimentation.
