Wireless and electrical frequencies in the atmosphere that are transmitted in the lower frequency range between 3 kHz and 30 kHz are known as VLF or very low frequency. This is where the proposed VLF converter circuit comes to aid. This typical tuning arrangement neglects a majority of the interesting and uncommon signals found below the standard broadcast band. A huge number of general-coverage shortwave receivers start with the AM-broadcast band and rise in frequency to around 10 meters, or 30 MHz.
