Tech Tip: Fundamental vs. Overtone Most crystals are cut by the manufacturer with a fundamental frequency below 20MHz because higher frequencies would make them so thin that they would be extremely fragile! Most crystals below 20MHz are labeled at the "fundamental" frequency. Some about-13mHz crystals are labeled with the "fundamental" frequency but are used at the "2nd overtone" in a tuned (CB) circuit. Most common crystals for CB & HF amatuer applications are labeled at the "3rd overtone." Many crystals labeled from 23 to 54MHz are cut with a "fundamental" that is 1/3 of the (labeled) operating frequency.
The tuned circuit on the output of the oscillator determins the output frequency. Example: a crystal labeled 12.190MHz could be used at 12.190mHz or 36.570mHz; a crystal labeled 36.570mHz could also be used at 12.190mHz!
Crystals for Amateur VHF (High Band aproximately 150mHz) applications are typically used in an oscillator plus a "multiplier" circuit for higher multiples of that first oscillator. Example--many old Amateur/ham 2 Meter transmitters use crystals cut for use in an oscillator that is 1/9th or 1/12th or 1/18th or 1/24th of the operating frequency!
