In college we had an I2C to ethernet adapter on our drone testbed that caused all sorts of RF interference for us. We eventually wrapped the whole fuselage in a farraday cage so that the datalink and flight controls wouldn't be overwhelmed. It was responsible for transmitting data at a 1 Hz rate, and we could visualize the interference on a spectrometer over a broad range of Rf at exactly 1 Hz. Anyway, we totally could have made a transmitter out of that thing.
