EbNaut Information for LF

Status of EbNaut and this page

EbNaut may be the ultimate weak signal mode for low and very low frequencies but it requires extreme precision in frequency and time calibration. For many, understanding the technical and operational aspects of EbNaut is a challenge. As I have struggled to understand the mode and required equipment setup myself, I have heard from others who are just as baffled. I hope to assemble here a collection of EbNaut informatiomn which may be helpful to the newcomer, including tutorials and successful EbNaut hardware implementations. The main focus will be on EbNaut for LF (the 2200 meter amateur band).

EbNaut home page for background, technincal information, software, etc.

It is suggested one read and try to understand the material on the above linked page and to seek other sources of information. As an amateur radio licensing instructor and one who appreciates knowledge of how things work, I feel it is always worthwhile to understand as much as one can. That said, this is very complex stuff, often overwhelming to the average amateur radio operator or LF enthusiast. Technical complexity, limited publishing of information and lack of a consolidated repository of information have contributed to slow expansion of EbNaut on LF. It is the aim of this page to address those points.
