Amateur communication needs to make the most of propagation lifts. We also strongly endorse using DFCW, rather than single frequency QRSS, as DFCW is: - significantly faster for completing a message; - distinctive from carrier type of QRM and; - the dual frequency coding has an extra degree of freedom for making decisions on what has been received (displayed). 73, Bob ZL2CA
