This document describes tests conducted jointly by the Advanced Engineering Laboratory AEL and the Electronics Research Laboratory ERL at the Defense Research Centre Salisbury DRCS, in December 1981 which attempted to real-time frequency manage HF radio medium speed digital data transmissions between Townsville and DRCS, a distance of approximately 1900 km. Instrumentation which monitored the Doppler spectra of a CW stepped frequency sounder transmission originating in Townsville was used as an aid in selecting the optimum operating frequency. The work forms part of the HF Enhancement Study being carried out by AEL and ERL and is sponsored by DGJCE. Author
