Joe Taylor's work in weak signal propagation is phenomenal. His protocols are the basis of all the weak signal modes. You can use his methods to make contacts all around the world on milliwatts of power. The work started as a way to improve earth-moon-earth contacts. Yes, that's bouncing radio waves off the freaking moon and the path loss is around 275 dB for VHF frequencies that are commonly used.
