Pathloss 5.1 - revision date May 30, 2018
- XPIF value can now be edited in ACM links if there are no XPIF values in the radio file. Previously, in ACM operation, XPIF values from the radio file were used exclusively. User editing of the value in the pl5 file was not allowed. Now, if there are no XPIF values in the radio file (or they are the same for every modulation state) the user can edit the XPIF value from the CoChannel worksheet in transmission analysis. The value entered in this worksheet will be applied to all modulation states.
- The recommended method is still to add the XPIF values to the radio file so that they will be available for any new link the radio is used on. This is also the only way to get different XPIF values for each modulation state. The XPIF value is the far right column in the adaptive modulation section in AntRad.
