To be pedantic, the crystal is the rectifier in a crystal radio. Tuning was (or is, since there are still people out there playing with these things) still usually done via a normal tuned LC circuit.
But yeah, we've gotten a lot better at rectifying too.

- ElevenLathe 2y agoThat's not what is meant by "crystal radio".
- marshray 2y agoYes, absolutely. I was referring to the part about "still usually done via a normal tuned LC circuit". Sorry for any confusion.
