We are pleased to announce the NEW and LATEST release of ACE-HF - PLEASE view this press release.

ACE-HF PRO is the most advanced and the most accurate high frequency ionospheric radio signal propagation modeling and forecasting software for amateur radio (HAM Radio) and shortwave radio listening (SWLing) operators, in the World.

ACE stands for Animated Communications Effectiveness, a coverage display technique originally developed for U.S. Navy submarine communications. ACE-HF PRO is the System Simulation and Visualization software written for HAM Radio Operations and Short Wave Listener Operation. See the reviews, below, for the full details on the features for Ham Radio and SWLing.

The ACE method shows a sequential series of coverage maps. When the maps are animated, a movie is shown that displays reception of the signal in question. This helps you see in a glance what operating conditions are like during the period you are modeling. In addition, all graphs and circuit analysis results can be animated, to give you a complete picture of what's expected in the model you are displaying.

Below is an example movie created by NW7US that illustrates the footprint (area coverage) over 24 hours during July 2011 of a 25-watt and a 50-watt JT65A digital signal using an isotropic antenna. JT65A is a weak-signal mode, so using 50-watts is more than typical, but for the sake of illustration, is helpful in creating this movie that reveals the coverage that such a signal has even while the Sun is not very active. The ACE-HF Pro analysis for this movie is based on a monthly smoothed sunspot count of 25.



ACE-HF's advantage is that the effects of the day's passage may be easily understood, and can easily be changed during your engineering sessions. ACE shows when the HF bands will be open in different world areas. ACE-HF is for Ham and SWL operators. It offers easy-to-use features that give you an edge during your planned operations.

I have compiled several reviews and tutorials on ACE-HF, and on topics that are essential to communications circuit analysis using tools like ACE-HF. The following menu offers the online versions of these resources. These are edited versions of materials that I have published in CQ Magazine and in Popular Communications.
