I asked the question because I didn't understand how the crystals work and what the difference is to the resonators...As far as I understand now, the crystal amplifies ac noise at its resonant frequency at startup until everything is in synch with its resonant frequency...So there's a 5volt AC signal present there? I'm guessing I could pull one line into the comparator, and use the comparator output...Would that help to extend the wire?
