Measuring crystal resonators with GDM is easy but not very accurate. This method is useful for determining the crystal frequencywhen the label has worn off. All you need to do is connect a few turns of wire around the GDM coil and connecting that loop to the crystal. The resonance will be very steep so you need to tune … See more Grid Dip Meters are called like that because back in the day they were made using triodesand used to measure the oscillator amplitude … See more The circuit shown here comes from a book called “Konstrukcje krótkofalarskie dla początkujących” by Andrzej Janeczek, call sign SP5AHT. It is … See more To measure the resonance frequencies of an antenna (such as a dipole) wind a few turns of wire around the GDM coil and connect it to the antenna connector. Tune the GDM and exchange coils until you see the dip on the meter. … See more The use of a Grid Dip Meter as an inductor-capacitor resonant circuit resonance measuring device depends on the circuit. If it is just a resonant circuit, not connected to anything and with the coil exposed, you just … See more WebMay 18, 2024 · The current flowing in to the source (grid) produces voltage drop proportional to the impedance offered to that particular harmonic frequency component.
