A current research and experimentation effort of mine is Coherent CW, or CCW. This is a technique of synchronizing the transmitter and receiver's keying to provide great improvements in S/N over conventional methods of CW communications, thus enabling copy of some very weak signals ... a particular advantage in QRP operation. My approach is to build off the great pioneering work done by Bill de Carle (et al) through application of a modular DSP component.
