Hi Terry
You sure are right, I am confused and with good reason. I admit to knowing next to nothing about the properties of crystals prior to starting this thread..
One of the points I was attempting to show was; if you look at the last crystal on the left half of the table, it would seem clear that the manufacturers expected the crystal to produce a lower third harmonic. The fundamental frequency is 2.92 times (almost 3times) the marked frequency. Yet it does not produce any lower harmonics that I can detect on my radio. Maybe it would in a different oscillator circuit.
