Another useful crystal oscillator is the overtone oscillator shown in the schematic below. Standard-cut crystals are difficult to make; higher than 20MHz as the wafer of quartz becomes too thin. A solution to this is to use an overtone oscillator. An example is the frequency source for a 144MH transmitter. http://jingzhen95.com/OscillatorCrystal.html
