VLF amateur radio

For several years I have tried to maintain a website about VLF amateur radio. Experiments are mainly done by a few keen amateurs. To receive VLF amateurs does not require a big antenna. To radiate a VLF signal to some distance does require a big antenna.

A casual listen at VLF will not result in success with amateur VLF signals. Most require highly stable signals (usually locked with GPS or a VLF MSK commercial signal) and integration over many hours or even days.
