Here is the video I saw this in:
I do think this vid is legit but maybe Ive been had.
I think I understand how he could listen to a single radio station doing this but how is he listening to two of them using 2 LEDs that are connected to the same leads? This one has me really stumped.

If you think that’s wild, wait until you [see what happens with a bigger antenna and a hot dog](https://www.youtube.com/watch?v=GgDxXDV4_hc).
The reason they’re picking up multiple signals at the same time is that they’re not using anything in their setup to selectively tune to a specific frequency. It takes more work to make a system that selectively amplifies a narrow frequency band. That’s part of how radios work, by being able to selectively tune only specific frequencies. If you don’t include the parts of the radio that filter out all the other frequencies, you pick up a lot of noise from all the stuff you’re not trying to listen to.
