The CDG2000 Transceiver<\/p>\n

This site provides supporting material to the RSGB series of articles on the CDG2000 transceiver. The aim is to provide the reader with the supporting text to the series either to explore issues in more depth or to provide additional material such as user guides, software, pcb artwork and performance data. It will be extended as the series progresses in RadCom.<\/p>\n

All materials provided here are copyright Dave Roberts G8KBB, George Fare G3OGQ and Colin Horrabin G3SBI. In all cases, materials are provided for the purpose of self education and training in Amateur Radio. No use may be make for commercial purposes without permission of the authors. PCBs and some components are available from the authors.<\/p>\n

**June 2005 ** Information Updated – New PCB details & documentation (many changes).<\/p>\n

Information is currently available on the following subset. Links have now been fixed Jan 2015 (Webmaster)<\/code><\/p>\n

Note that PCB data are shown now as PDF files. If you print out at 100% scaling, you will get 1:1 artwork for producing PCBs.<\/p>\n

We could not get all the material on the website \u00a0so if you want the articles with the hi res pictures, we can supply a CD on request. Note – best viewed at 1024×768.<\/p>\n

**UPDATES**<\/p>\n

June 2005 \u00a0Relaced all PCBs and most schematics to correct numerous minor errors. New documentation in many places.<\/p>\n
