    • For prediction I use using Ace HF Pro and IONSUM, which are computer programs using the output of the IONCAP prediction method to determine the most suitable frequency band and required antenna gain under specific averaged conditions. The acronym stands for IONCAP SUMmary. Propagation predictions form an essential tool in the management of a HF wanting to work DX Stations. The data from such predictions are used to specify the types and operating frequency ranges required to work the DX by allowing for changes in the antennas take off angle to achieve maximum signal to the desired direction. Which it is used to contact DX stations utilizing both long path or short path on F layer, or to contact North American stations on daytime.
    ACE HF Pro, by Long Wave Inc allows me to analyze the entire HF spectrum using a single fixed transmitter location and multiple receive locations. The 64 Bit application has enhanced features and uses Google Earth and Google Maps to provide detailed HF Area Coverage Maps.

    Yes, in fact I updated my software a few months ago.
    Long-Wave who owns the copyright on Ace is a defense contractor based in Oklahoma City and is very active in various Department of Defense Communications programs.
    They have a general program low cost program which hams or which anybody can use and a high-end program which is proprietary for defense department contractors/usr.
