Optical Communications

One of my favourite things before my 2013 stroke was experimenting with optical communications. I had some success with "over the horizon" weak signals.  No sign of the red light was visible, yet it could be detected miles away non line of sight (NLOS) with a laptop. These days I am just too wobbly to do this.

As I have said before, test gear is easier than microwaves and all the kit can be made in a shed for very little money. This is an area rich for experiments and right at the frontiers.
