One teen sent a “secret” scheme of the transmitter for listening at a distance of 1 km. This “secret” scheme went from hand to hand and came across to me. I proposed a scheme of this transmitter, to really succeed. But he proudly rejected “my crap” and ran to collect details … The main-battery 1.5 volt, he had already acquired. Well, how to convince him? About Ohm’s law he had not heard … Why the scheme should work?
