I think the important point to note about that is it doesn't necessarily have to be a purpose-built "radio transmitter" to emit RF energy; everything which involves moving charges will radiate an EM field. This becomes especially apparent when you read the century-old books on early experiments with radio, and see the extremely crude circuitry they used to generate those waves.

Absolutely, if you turn on and off a light switch while listening an AM radio (even static) you would hear it through your speaker, as in this demonstration [1] (it worth watching the whole video if you are interested).
