VLF

Important Notes This receiver went offline on August 10th, 2025, due to extensive storm damage. I have not yest decided if I will re-create it at all, or bring it back in a different form. I am leaving this information here because this receiver setup was very low noise, and quite performant over the years it was in operation. VLF E-Field Receiver This page is a summary of my current E-field receiving system, and is constantly being updated as I try different experiments to improve the system.

A High Bandwidth Low Noise Optical VLF Link This is an article that I wrote which first appeared on Renato Romero’s website vlf.it. It describes the design, characteristics and use of a high bandwidth, low noise optical system for connecting a VLF receiver to a data sampling system. This easy to build, inexpensive system has a flat response to over 200KHz, and a noise curve well below the VLF band.
