Determine if the image frequency for the VOR/ILS Nav falls within the range of
the NTX138 unit. If so, select two sets of frequencies that will cause the NTX138
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. Record these
values in the spaces provided in the following chart. Modulate the NTX138
transmitter on the following frequencies for at least 20 seconds. Listen for any noise or
detected audio signals on the receiver audio; look for any movement of flags or needles
