Ask the control centre if they are measuring the expected power level for the CW. If not, it
is likely that the antenna pointing is not optimal. Fine-adjust the antenna pointing until the
CW power level detected by the control centre is within their requirements.
6.3.4 Fine adjustment of antenna polarisation
Ask the control centre if the measured level of the CW on the crosspolar transponder is below their
requirement. If not, fine adjust the rotation angle of the Rx/Tx/Feed Assembly with respect to the feed
horn until the polarisation discrimination is within specified limits.
