The CDG2000 Transceiver
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.
