Below you will find my VLF Signals channel on USTREAM. This channel broadcasts a live feed from my the PC desktop housed in the VSOR Observatory. A small loop antenna, tuned with an Elenco K-38 capacitor substitution box, is connected to the sound card microphone input jack. The signal from the card is processed using Spectrum Labs, a freeware sound analysis program. 24.0 kHz is the broadcast frequency for the VLF transmitter at Cutler, ME (callsign NAA). This station is one of the largest of its kind and transmits at 1,000 watts, with peak ouput around 1,800 watts. The purpose of monitoring this station is to indirectly observe Gamma Ray Bursts (GRB’s) and Soft Gamma Ray (SGR) events.
GRB Detection Research and Resources
The indirect detection of GRB events utilizing VLF radio antennas is a relatively new observing technique. The usefulness and potential application for this method is the topic of several scientific research papers, articles, and presentations. Below I am collecting any and all material on this topic.
