If you are a ham radio operator of a certain age, you probably remember ads for “The Instructograph,” a mechanical device for learning Morse code. [Our Own Devices] has an ancient specimen of ...

Field tests are performed and analyzed to assess the accuracy of the LWNFS model using measurements of very low frequency (VLF) transmitter signals scattered by electrically-small metallic boxes with ...

Abstract: Accurate prediction of the diurnal variations of very low frequency (VLF) waves in the Earth-ionosphere waveguide is still a challenging task. In this letter, a novel method, which consists ...

The antenna though presents a problem. You might think that attaching a long piece of wire to the microphone input would be enough, but the problem is that due to the huge wavelength of the VLF ...
