It still lives on - in an admitted niche - in amateur radio teletype digital modes. Because RTTY uses a very simple FSK coding scheme, it survives amplification from nonlinear amplifiers quite well. It means you get teeth-rattlingly loud signals blasting in from stations worldwide. Usually all over your carefully crafted low power signal ... grar.
