A drill string sub for a rotary steerable drilling system wherein a flow diverter is configured, which flow diverter is configured rotatable about a drill string longitudinal axis at a relative rotation frequency relative to the drill string sub, to preferentially direct drilling fluid into a selected azimuth segment which is stationary relative to the flow diverter. A downhole data unit is configured to provide an information signal representing downhole data. An encoder operatively connected to the flow diverter to modulate the relative rotation in accordance with the information signal for transmitting information representing the downhole data to be detected uphole.
