The DSP Interchange for Weaksignal Communication and SETI.

Large racks with with mercury vapour rectifiers in the bottom, the light intensity of the bulbs in the house being modulated by the rhythm of the transmitted code, and high towers loaded with aluminum are becoming more rare and hard to efford in today's developed world, especially for younger people with limited resources.

Some of the areas with increased activity and interest are all kinds of low power (QRP) applications, for operating as well as construction, advanced receiver design and the utilization of computing power for the enhancements of the communication process. In addition to this, computers enable better research and design for antennas. In this connection it is worth noting the increased interest of amateurs in radio astronomy, meteor scatter, satellite communication, VLF (Very Low Frequecy) and the observation of natural radio phenomena.

The purpose of this page is to draw attention to the developments that have been in progress for at least a last decade or more. This is certainly not intended to force anything on anyone.

Although many in the amateur radio community are resisting this development, the scientific and military defense communities have seen this years ago.
