Simplified Tools and Methods for Measuring CrystalsByJim Kortge, K8 IQYS ummaryThis paper describes an approach for measuring crystal parameters using relatively simple testapparatus and test setups. Some of the required test instruments are easily built, usingManhattan-style construction Methods . Others can be obtained on the surplus market at low careful use, the resulting crystal parameter values are comparable in accuracy to thosemeasured with instruments costing thousands of dollars. The same instruments and setup canalso be used for measuring crystals for use in multi-pole of the common elements in all modern superheterodyne receivers is at least one crystal contest grade receiver may employ more than one filter for improved performance. One canobtain a crystal filter essentially two ways; either purchase a commercial unit on the required IFfrequency or build the filter from easily obtained the filter requires little effort, but the cost is high, on the order of $ , and maybe much more than this amount for a high performance filter.
