My electrical engineering class is near the end of the semester and we've started working on a design project. The goal of the project is to create a very sensitive AM radio. During each round they will decrease the power of the AM signal and whoever can still here the variations in the signal stays in.
For mine I have a few ideas and was wondering if you guys had any suggestions.
First, I was thinking that we filter the signal with an active band pass filter that would amplify the signal as well. Or maybe just use a passive filter and then amplify the signal with a transistor. For the antenna I was thinking a wire loop antenna like

Anybody else have some good experience with this that could give me some suggestions?
