ABSTRACT:
A high frequency communication system has at least two stations with each station having a discrete address, a transmitter, a receiver and a means for selecting the preferred frequency for transmitting at least a preselected format between the station includes a means for sequentially tuning the receiver through a group of channels with each channel having a preselected frequency and bandwidth, a means for measuring the link quality of each channel that is received according to the discrete address of the station transmitting the message. After the link quality is measured it is stored in a link quality matrix according to the channel and address of the station transmitting the message, so that when transmission is initiated by the station receiving the message it may select the channel with the best link quality and initiate transmission on that channel if it is available.
