Determine if the image frequency for the VOR/ILS Nav falls within the range of the TDFM-136A. If
so, select two sets of frequencies that will cause the TDFM-136A to be set a close as possible to
the image frequency. Chose one set in the localizer frequency range and one in the VOR
frequency range. Record those values in the spaces provided in the following chart. Modulate the
TDFM-136A 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 moment of flags or needles on the
navigation display.
