What electronic tricks can be done next to a crystal controlled police scanner?



Answers:    Tricks? A police scanner is just a radio heir, just approaching the one in your motor, except on a different frequency band. What electronic tricks can be done beside your car radio?

'Crystal control' sounds shimmering, but it's really not. In the old days, elevated frequencies were knotty to maintain, due to simple steam properties, instability of components, and loose tolerances. A crystal provided an extremely stable base frequency from which other frequencies could be derived. Today, beside microprocessors, nanotechnology, and extremely tight tolerances, it's not so necessary anymore.
