Re: Spitfire AM Transmitter Hum (Buzz)
Yes UK law is draconian. More or less, it says:
"thou shalt not emit electromagnetic radiation".
Except, that is, when you have a License to do so. Some devices are implicitly licensed, mobile phones, two way radios in approved bands, wireless routers and some remote control devices.
More exotic interpretation of the laws of physics tell us that we are emitting EM radiation just by not being at absolute zero and when we move (as in wave/particle duality). The list of other "violations" is extensive...
There are of course very good reasons for strict control of the EM spectrum and there would be chaos without it.
