chinese sell FM/AM radio transmitters that have power ranges which far exceed FCC guidelines, they get past this by 1. not caring, 2. putting a dinky antenna on. 3. putting a warning on it, telling you that you can only broadcast so many distance
However, the antennas they use can be switched out with those baofeng whip antennas or even larger ones and can be operated in a very illegal way which i do not recommend Σ(;;ﾟДﾟ)
