All true, but several people have reported TSOs telling them these are "sound" waves. I find it difficult to believe that several independent, and ill-informed, people would all manage to translate "radio" into "sound" and impart the same incorrect information.
One person on FT even reported being told "these are sound waves, just like an ultrasound". That goes way beyond confusing two different terminologies. Either the TSO was told a MMW is "just like an ultrasound" or they made their own interpretation, which is just as misleading.
