VLF Stream

The audio stream here will change from time to time depending what i find interesting.

It will not always be online!

19.8 kHz (NWC) Disconnected 0 kbps
+10 dB (3.16x)

How it's working so far...

VLF-Tools is receiving and converting the signal to near baseband and taking one sideband, then a bit of python code is sending this raw data via websocket to my webserver. This page reads from the websocket, plays the sound and displays the spectrum/waterfall. It's very bandwidth hungry right now but it's just raw data, i'll add compression soon to fix that.
