01

Artifact Overview

This wavemeter was likely developed by the US Army Signal Corp for military use. Its purpose is twofold: to detect the frequency of an incoming signal, and to check the frequency and harmonics of an outgoing signal. Early radio operators, working with multiple and specialized technical components, used wavemeters to determine the clarity and strength of their transmitters.
