Shortwave is regulated like AM/FM. Supposedly pirate stations appear temporarily. Ham radio is, and always been regulated. No obscenity but they don’t enforce it. Uses of ham radio are limited: no commercial use, no broadcasting, and no encryption. CB is open. It has same obscenity rules but not enforced. They don’t enforce the power limits. But CB has the lowest range of line-of-sight. FCC doesn’t enforce rules because they don’t care, partly cause dwindling numbers use them. If the FCC card, they could enforce heavily.
