NOTES:

C. Determine if the image frequency for the VOR/ILS Nav falls within the range of the TDFM-

600/6000. If so, select two sets of frequencies that will cause the TDFM-600/6000 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 those values in the spaces provided in the

following chart. Modulate the TDFM-600/6000 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.
