Using a PC sound card to receive VLF radio signals
Just connect an antenna to your computer's microphone input, and you can receive VLF (Very Low Frequency) radio signals! A sound card (or built-in sound chip) with a recording sampling rate of at least 96 kHz is recommended.Example of using this method to receive VLF signals from Russia and Europe:http://www.youtube.com/watch?v=fKSOoZ2vhvoSDR ...

Dear friends, we are doing some VLF testing at YO3BN station and hope to open the VLF SDR soon to public. The Very Low Frequency (VLF) ranges of the electromagnetic spectrum reveal a fascinating world of natural and artificial signals that are otherwise inaudible to the human ear. These frequencies, typically between 300 Hz and 30 kHz, carry information about Earth's dynamic environment and even activity from beyond our planet. What Can Be Heard in VLF? Using specialized receivers, we can listen
