Many factors were considered in the design of this outstanding instrument, resulting in a grid dip meter that is packaged with desirable features.
With the oscillator not energized, the instrument acts as a absorption wave meter on high signal level circuits. 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.
Plug-in coils can be quickly changed, and cover the frequency range from 2 mc to mc continuously. Notice that one hand operation is possible.
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, hrathkit RF circuit resonant frequencies, aligning IF stages, traps and filters, and correcting TVI.
Transformer operated with selenium rectifier. Dial correlation curves are included.

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.
A variable sensitivity control assures adequate range of sensitivity throughout the entire frequency range. Spare, blank dial scales are supplied for the builder who wishes td-1b hand-calibrate this particular instrument, or desires maximum accuracy at specific frequencies.
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 jeathkit 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.
