To do this test I shall need to aim my QRSS3 optical beacon at the windmill and use a PC with Spectran software and sensitive detector and optics at the remote site. I have tripods but they are not the world's best.
As it is some time since I used the gear, I need to do some local tests first to check all is well.
Optical work is fun as all the gear is homemade and test gear is simple. In my view this is more fun than microwaves. It is accessible to all. All you need are a weak light source, a scope, free software and a multimeter.
In my healthier days I had a lot of fun detecting my QRSS3 optícal signal over the horizon There was no sign of the signal visible by eye, but on the PC screen it was very clearly visible.
