A Modern GDO–– The “Gate” Dip Oscillator

A Modern GDO–– The “Gate” Dip Oscillator When you are troubleshooting a receiver, a GDO can help isolate the fault. Tune the GDO to each of the IF frequencies, starting with the last and hold the coil close to that part of the circuitry. If you can hear a signal, then that IF and all the cir-cuitry after it are working.

Dip Meter: Grid Dip Oscillator GDO » Electronics Notes

The dip meter or grid dip oscillator is a relatively simple item of test equipment. This provides advantages and disadvantages. Essentially the dip meter or GDO is a very simple instrument, but one that can give a considerable degree of insight into various aspects of the performance of radio frequency circuits and elements.

How to Use Grid Dip Meter / GDO » Electronics Notes

How to use a grid dip meter to estimate the Q of an inductor: This method is fairly rough and ready but entails using the dip meter to tune either side of the resonant frequency to a point where the dip is reduced by about 30%. These two frequencies can be used to

GRID DIP METER QSL.net

This name came from the golden age of tubes, but today, in the era of semiconductors, that name became gate-dip-meter, dip-meter or simple, dipper. Under various appearances, the GDM, in essence, is just a variable frequency oscillator tuned in a wide range using additional plug-in coils, connected to an electronic voltmeter.

A Real Grid Dip Meter

A 'Grid Dip Meter' or "Oscillator' (GDO) is a relatively simple piece of test equipment consisting of a tunable oscillator with an exposed plug-in coil for covering a wide range of frequencies. It has a sensitive meter to measure grid current as an indication of the strength of the oscillations. Any
