[Boatanchors] FT-243 crystal sockets

[eldim at att.net]

Hello Steve & Crew,
1.  I thought the front Crystal Socket of the Viking Transmitters were an OCTAL 8-Pin TUBE SOCKET which can accomodate up to two (2) FT-243 Xtals!  
2.  I'm not much on CRYSTAL THEORY so I am wondering what is involved in using the smaller size Crystals such as the CR-18, CR-23, or whatever the number.  Since, a crystal operates on a Fundamental Frequency and also on Harmonics, which I understand is determined by the "Cut" of the Quartz.  Also, the Frequency determines the thickness, plus probably other physical dimensions of the crystal as well.
3.  Then there are voltages and associated circuitry necessary to drive the crystal into oscillation, and a feedback necessary to sustain oscillation.  Now we add a trimmer capacitor to fine tune the oscillator frequency.  
4.  So the real question to the group is, "WHAT CRYSTALS WILL WORK WITH DIFFERENT SETS, or is there a table defining Crystal Characteristics for a given crystal type?
