Hey i was wondering if someone can help me out with radios and whatnot...i know making transmitters are illegal but i was just curious as to how they work as well as receivers. The thing that confuses me is how do you get information to and from the signal? I mean if i made a tank circuit that would oscillate at a certain frequency, how would that actual resonate with the electromagnetic wave? I to make it resonate you need a inductor and a capacitor but if i didn't apply power to it, would it be possible just to send that to a step-up transformer? would that be enough to listen to the audio encoded in the carrier wave (considering its am) after sending it through a speaker? Also can somone explain to be the whole thing about calculating indutance? The whole thing about finding the values with ought proper equipment is a bit hard to do heh. Sorry i am not the best at electronics but i would really like to become better. If possible can someone draw a quick schematic? I have seen some but they look like they are designed for quality rather then theory. Thanks a lot. Hopefully ill be smart one day haha.
