Electron-density true-height profiles are calculated from automatically scaled Digisonde ionograms. The profile algorithm uses the modified polynomial fitting method separately for the E- and the F-region profile calculations. A new approach to considering the transition region between the E and F layers allows to determine the F profile with good accuracy from the ordinary echo trace. The total electron content between the peak of the E layer and the bottom of the F layer is estimated to account for the observed retardation as a function of frequency on the F trace. No effort is made to find the valley shape since this is not possible from the O trace alone. The new algorithm is tested on some model ionograms.
