No, it's not an adf enhancement. It is the re-creation of the radio signal transmissions used to navigate in the 1930's and 1940's, before the advent of the more modern navigational aids. ADF was introduced around 1945. Basically, it is a radio range receiver, the radio transmission stations/freqs and in the most modern of the panels, a sextant to plot the stars. There is much more in the package, but that is the basics of it.
