Measurements Model 59 grid dip meter without original coils Update Original Coils received! See below. The Measurements Corporation Model 59 "Megacycle Meter" is arguably one of the best grid dip meters ever made. Its large meter, separate head, quality of components, and regulated power supply are part of why this is a preferred grid dip meter.

Questo GridDip Meter, ma sarebbe meglio definirlo GateDip Meter, era nato per le UHF, e quindi iniziai con la bobina per le frequenze piú alte. Con questo esemplare sono riuscito a raggiungere 500 MHz: la bobina è in effetti un condensatore a pasticca da 18 pF saldato sui reofori della presa volante GBC GE/065200.

Apr 22, 2005· Basically a grid dip meter (dipper, dip meter) is used to determine the resonant frequency of a circuit. They can be used to determine the inductance of a coil, the capacity of a capacitor, the resonant frequency of an antenna, etc.

A used grid dip meter () will let you get the resonant frequency—not necessary here—and a used () noise bridge will let you deal with impedance issues, but is not necessary with simple antennas like this. Simple antennas are easy to build and work well. Height is a big plus. Just get in there and klutz around until it works.

The very same things that allow a tube to be a good amplifier tube on VHF and UHF make it a stable tube at HF. The least stable tubes are those with poorest VHF and UHF performance. If a tube is useful and stable at VHF or UHF, it will be even more stable in a properly laidout HF amplifier system.

OF COURSE the grid dip meter is a valuable tool. I wouldn't be without one. There is a certain technique involved and a bit of knowledge. 1. The dip is sharpest and deepest if the circuit is unloaded by any resistive components. In this sense, a low Q ferrite can act as a parallel resistor and may completely obscure the dip. 2. Tune slowly. 3.
