FliteLine Automatic Direction Finder (ADF)
General Description
The Chelton CDF-552 ADF Control Display provides control to Automatic Direction Finding radios enabling
reception of low-frequency navigational aids and AM broadcast stations in the 190.0 – 1860 kHz frequency
range. The CDF-552 provides a direct replacement of the Series III CD-432B Control Display Unit, for control of
the DF-431B in the DFS-43A system.

The CDF-552 Control Display along with an ADF radio system provides accurate, dependable reception of
enroute non-directional beacons (NDB), Locator Outer Markers (LOM), and commercial AM broadcast stations.

Microprocessor circuitry controls operation, processes signals, performs self -calibration, and provides full-time
self -diagnostics. The CDF-552 may be used with Electronics Flight Instrument Systems (EFIS) or in
conjunction with the other Chelton VHF Navigation Systems for course deviation display.

The CDF-552 configured for Series III or FliteLine displays frequencies in the range 190 kHz to 1860 kHz and
the international marine HF distress frequency of 2182 kHz. The CDF-552 configured for BCD tuning displays
frequencies in the range 190.0 kHz to 1749.5 kHz. The active and standby frequency are displayed
simultaneously and stored in nonvolatile memory. Switching between the two is done by simply pressing a
frequency transfer button below the displayed frequencies.
