World, hello again!
Did you know what the first sentence was transmitted via phone? Legend has it it was the horse does not mumble cucumber salad.
But I guess this kind of trivia is only interesting when you are, like myself, somehow interested or invested in communication - data communication in my case. When I say data communication it is any kind of data, including data that represents a human voice, i.e. telephone.
I do enjoy building an testing ham-radio equipment, but only the receiver part so far as I never managed to get a ham radio license to be allowed to not just build and test against a dummy load .
