Complete manual for the Heathkit GD-1B grid dip meter. With compliments, Jogi, Grid Dip Meter GD-1B Equipment Heathkit Brand, Heath Co.; Benton Harbor MI Select picture or schematic to display from thumbnails on the right and click for. The first Heathkit Grid Dip Meter was the GD-1 and it came on the market in It was replaced in by the slightly improved GD-1A, which in turn was.
This set is the 3-prong mounting type and provides continuous extension of low-frequency coverage down to kc.
Many factors were considered in the design of this outstanding instrument, resulting in a grid dip meter that is packaged with desirable features.
Spare, blank dial scales are supplied for the builder who wishes to hand-calibrate this particular instrument, or desires maximum accuracy at specific frequencies. Can also be used to roughly determine capacitor and inductance values, and to provide a relative indication of power in transmitter stages.
A variable sensitivity control assures adequate range of sensitivity throughout the entire frequency range. Transformer operated with selenium rectifier.

GD-1B Grid Dip Meter Radio amateurs and servicemen have proven the value of this grid dip meter many times over, indispensable in the service shop, the laboratory, or the ham shack, for locating parasitics, spurious oscillations, neutralizing, determining RF circuit resonant frequencies, aligning IF stages, traps and filters, and correcting TVI. Plug-in coils can be quickly changed, and cover the frequency range from 2 mc to mc continuously.
Dial correlation curves are included. Notice that one hand operation is possible.

Plugging headphones into the phonejack further extends the instrument’s usefulness through operation as an oscillator-detector for determining the frequency of other oscillator circuits through zero beating. The grid dipper may be held in one hand and tuned, leaving the other hand entirely free for making circuit adjustments. The GD-1B incorporates its own power supply and is transformer operated from the power line.
Originally the grid dip meter found its greatest application in the amateur radio field, but now it is used extensively in radio and TV servicing and in experimental laboratories.
