A system and method are provided for generating and/or refining an active frequency table (AFT) for High Frequency Data Link (HFDL) communications, particularly those communications managed by a network of HFDL ground stations. Automated analysis is applied to forecast atmospheric conditions to generate an AFT for the HFDL communication network for one or more particular time windows. Historical analysis of measured atmospheric conditions is consulted to provide an approximation of an AFT. The use of the historical data includes determining, in a past time frame, when an atmospheric conditions most closely compares to the measured or forecast conditions. Reference is then be made to stored information regarding one or more AFTs that were effectively employed in the past time frame under the comparable conditions to generate an appropriate AFT according to the measured or forecast conditions.
