A Modern GDO The Gate Dip Oscillator - PDF Free
A GDO is a tunable oscillator with the coil mounted outside of the chassis. The external coil allows you to measure the frequency of a tuned circuit without any electrical connection to it. Just bring the coil close to the tuned circuit s coil and tune the GDO while watching for a dip in its meter reading.

GRID DIP METER - QSL.net
2003-1-26 GRID DIP METER. A very useful instrument into the every respectable ham workshop is, without any doubts, the grid-dip-meter. 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 ...

Grid dip meter - Angelfire
Avoid any circuits similar to the Heathkit tunnel dipper. The meter deflection is small and the dip is right on the edge of being imperceptible. The Millen type 90652 "Solid State Dipper", pictured at left below, uses a 3N128 duo gate MOSFET as the oscillator device. There is also a meter amplifier using BJTs.

2019-11-15 Modern GDOs are not made with vacuum tubes, but with transistors – preferably JFETs or Dual-Gate MOSFETs due to their high input impedance that makes the oscillator more stable. GDO’s with transistors can be called as TDO or TDM (Trans dip oscillator/meter). They can also be made with a tunnel diode (tunnel dip oscillator/meter) instead of ...

GRID DIP OSCILLATOR by Harry Lythall - SM0VPO
2017-12-18 As regards the lower frequency limit of the GDO, there is no lower electrical limit. My original GDO covered 80kHz and I used a mains transformer coil to try lower limits. I had it down to much less than 1kHz. Unfortunately it was with the iron core, which made it useless as a dip meter, but it worked as an oscillator.
