It's wild how easily things can act as AM receivers. A pencil and rusty razor, or a tooth filling and saliva.

- nomel 2y agoWhen I was taking my electronics courses, it was fairly difficult to not build an AM receiver. Any time we were working with PLL or high gain amplifiers attached to a speaker, you'd eventually hear AM talk radio come out of someone's project.
- harkinian 2y agoYeah, it's just a bandpass filter (very easy to make by accident) and an amp.
