Funny: "You can home-build a device that transmits a watt or two of power (the same amount as a fairly dim lamp) into the sky, and can be received thousands of miles away (imagine trying to do that with a torch, illuminating clouds so that their reflections in the ocean illuminate other clouds, so somebody with a telescope in a distant country sees it and picks up your message!)..."
- inetknght 7y agoWhat's funny about that? I think it's awesome.
- sliken 7y agoHeh, what's even more amazing is that it's not just one bounce off the atmosphere, but multiple bounces. With js8call you can do similar with other radios sprinkled around the planet, without prior coordination. What's even more wild is that under certain conditions you get a weird distortion... from the signal taking the short path between two points AND the signal taking the long patch between two points. Freaky.
