More Information
Summary:A transmitting station in an ionospheric link varies the amplitude and phase components of signals fed to two orthogonally polarized antennas, to optimize reception at a desired location, based on prediction of the most favorable mode. Standard prediction software may be employed, taking into account current solar activity, and information derived from the return path. Independent claims are included for a method of HF communication and a transmitter and/or receiver forming part of an HF communications installation.
