    Once respective form is configured it should be applied to take effect. Desired C/N receive level on the remote Station (Desired C/N on local hub/SCPC side) should be set using TX level control form. This level should ensure proper quality of receive for the defined MODCOD. It is recommended using C/N values defined in the UHP specifications plus some (0.4-0.9 dB) margin.
