Part 4/7:
The core of the experimentation involves measuring the frequency of signals picked up by the antenna. The experimenter carefully sets up the multimeter, ensuring both leads are correctly attached, and then measures the frequency of the signals to determine their band.
The reading centers around 2,156 kilohertz (or 2.156 MHz), which the experimenter identifies as lying within the low-frequency range. They note that this frequency is not typical of common broadcast radio bands like AM or FM, nor is it part of television frequencies or standard powerline frequencies at 60Hz.
