A question: does this thing actually have individual crystals for the
different freqs (stations) it shows on its tuning dial? Or it has
circuits each acting like a crystal?


It's my understanding that it has a crystal for each of the programmed
stations. Each crystal is switched into the oscillator circuit by the
main tuning knob/dial. As someone said, it's like the early CB radios or
scanners, before PLL (phase locked loop) frequency synthesizers were
used. These require only one crystal to act as a reference for
generating a wide range of frequencies for complete coverage of a band.
