Sub 9 kHz News

*Roger Lapthorn G3XBM* provides the latest VLF news on the 'Sub 9 kHz' site

There is growing interest in amateur radio operation below 9 kHz in the
so-called '*Dreamer's Band*'.

Before 2010 few expected any real distances could be achieved by radio
amateurs at VLF. Radiated powers are low, antennas highly inefficient and
everything was stacked against success. However, with the advent of
powerful weak signal processing software and dedicated work by a few
enthusiasts, this has all changed. Some spectacular results have been, and
continue to be, achieved. The Sub 9 kHz pages bring together this work.

The Dreamer's Band covers 8.7-9.1kHz in the UK. This is the frequency band
allocated for experimental use by Notice of Variation to the Amateur Radio
licence. At the time of writing only a handful of UK stations are active on
VLF. In Europe, where licence restrictions are less onerous, it seems more
stations are becoming active every week. There is also interest in other
parts of the world including Alaska, mainland USA, Australia and Japan.

A number of stations have set up so-called "grabbers", receivers connected
to the internet so that transmitting stations and others interested can see
who is being copied and where.
