  • Grid dip oscillator - ipfs.io

    Grid dip oscillator (GDO), also called grid dip meter, dip meter, dipmeter, or just dipper, is a measuring instrument to measure resonant frequency of radio frequency circuits. It measures the amount of absorption of a high frequency inductively coupled magnetic field by nearby objects.

    You do this by holding the GDO's coil close to your coil under investigation, turning the GDO's tuning knob, a watching for a "dip" displayed on the GDO's meter. This is all done with the radio's power off. It works very nicely for crystal radios too! And, it can be used as an RF signal source too.
