Excuse my ignorance about the term, what does “crystal-radio stage of gravitometrics” mean in this context?

- AnimalMuppet 2y agoPrimitive. (Primitive radios used a crystal for tuning. We have since gotten a lot better at tuning radios...)
- ElevenLathe 2y agoTo 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.
- marshray 2y agoBut we do use crystals for generating a stable frequency reference, which is then used in tuning.

- 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.
