 Therefore, always connect a shielded transmission line from the RaspberryPi directly
 to a radio receiver, so as **not** to emit radio waves. Never use an antenna.
 
-Even if you are a licensed amateur radio operator, using PiFmRds to transmit radio waves on ham frequencies without any filtering between the RaspberryPi and an antenna is most probably illegal because the square-wave carrier is very rich in harmonics, so the bandwidths requirement are likely not met.
