  • Page 29 Determine if the image frequency for the VOR/ILS Nav falls within the range of the NPX138 unit. If so, select two sets of frequencies that will cause the NPX138 to be set as close as possible to the image frequency. Choose one set in the localizer frequency range, and one in the VOR frequency range.
