CRYSTAL TESTING (ELECTRONIC)
xx   CRYSTAL (ELECTRONIC)
xx   ELECTRONIC TESTING

Build a wide range combination crystal and transistor tester. Will test most common transistors and fundamental mode crystals from 100 kHz to at least 20 MHz.
CQ. THE RADIO AMATEUR'S JOURNAL Oct 1979 (v.35#10) pg. 63

CB crystal checker.
ELECTRONICS ILLUSTRATED Mar 1964 (v.7#2) pg. 66

Transistorized crystal checker for CB crystals.
ELECTRONICS ILLUSTRATED Jul 1966 (v.9#4) pg. 85

Crystal checker will also serve as a signal generator or band-edge marker. Est. cost: $10.
ELECTRONICS ILLUSTRATED Nov 1969 (v.12#6) pg. 101

Circuit for the classic Colpitts oscillator which can be used to test crystals from 1 to 20 MHz. If crystal is good an LED will light.
ELECTRONICS NOW Nov 1998 (v.69#11) pg. 6

Crystal tester can also be used to test lamps, switches, diodes, LEDs, cables, capacitors, printed circuit traces, connectors, etc. Uses only a few componants.
ELEMENTARY ELECTRONICS May-Jun 1977 (v.17#3) pg. 75

Universal crystal tester circuit is a simple Pierce oscillator with an LED go-no go display. The crystal must be good to light the LED. Est. cost: under $11.
MODERN ELECTRONICS [1] Jun 1978 (v.1#4) pg. 57

Simple circuit will quickly tell you if a crystal is good or bad.
POPULAR ELECTRONICS [1] Mar 1973 (v.3#3) pg. 72

Circuit used in conjunction with a signal generator and a VTVM will allow you to determine the frequency of an unmarked crystal.
POPULAR ELECTRONICS [1] Sep 1973 (v.4#3) pg. 24

Circuit to test crystals over the 0.1 -to- 10-MHz range.
POPULAR ELECTRONICS [1] Feb 1977 (v.11#2) pg. 77

Crystal checker circuit is essentially an oscillator/amplifier with a broad frequency range.
POPULAR ELECTRONICS [2] Oct 1989 (v.6#10) pg. 27

Crystal tester circuit will oscillate if the crystal under test is good. Can also be used to check a number of ceramic- and piezo-filter devices.
POPULAR ELECTRONICS [2] Feb 1990 (v.7#2) pg. 87

Crystal-coupling circuit can act as a simple interface for your circuits, or allow you to measure a crystal's value.
POPULAR ELECTRONICS [2] Aug 1995 (v.12#8) pg. 28

Pocket-size crystal checker for CB.
POPULAR MECHANICS Jun 1964 (v.121#6) pg. 175

Crystal tester. Small, battery-powered, easy-to-build test circuit will let you know if a particular crystal will oscillate.
RADIO-ELECTRONICS Apr 1983 (v.54#4) pg. 146

Multi-purpose CB test instrument will check the condition of CB crystals and aid in receiver alignment.
RADIO-TV EXPERIMENTER Feb-Mar 1968 (v.24#1) pg. 79

CB crystal tester checks for stability, activity and helps align receiver.
SCIENCE & ELECTRONICS [1] Dec 1970-Jan 1971 (v.28#6) pg. 32
