A ferrite loopstick will pick up stronger stations with no antenna at all but use more audio gain after the diode detector and reduce the regeneration to get adequate bandwidth or the sound will be muffled. Webb12 juni 2024 · The slug tuned inductor is a variable inductor having an adjustable ferrite core. The value of inductance increases or decreases respectively, due to the movement of a ferrite core into or out of the coil winding.
