New version of PropPlanner software released for Windows and Intel Macs

In 2012, I opened a web-based service at - VOACAP Propagation Planner ( This service provides VOACAP HF propagation predictions as numeric data, instead of fancy graphics. The reason is that the numeric data when filtered and processed properly offer more accurate HF predictions. And for this purpose you will need some extra software to help you. This is where my PropPlanner software for Windows and Intel Macs comes in. I also offer an Excel template which gives you CQ zone-specific summaries and thus helps create your own contest or DX operation plan.

As you know, making predictions boils down to making optimum use of the openings — being in the right place at the right time. So, the better predictions you have, the better basis for operating planning.

Nevertheless, we must remember that predictions are just that — predictions, not exact science. And in particular, due to the nature of VOACAP, you must visualize low-band openings with the help of grayline map software such as DX Atlas by Alex VE3NEA or GeoClock by Joe Ahlgren. VOACAP predictions are of less help there.

The resources needed for successfully running VOACAP Propagation Planner are as follows:
  1. Web site ( that calculates VOACAP predictions and outputs the result as numeric data, and
  2. Windows or Mac software called PropPlanner (together with an Excel template) that helps you work on the VOACAP prediction data on your own computer and make it more understandable.
The VOACAP Propagation Planner manual is available in PDF format.
Give it a go, and let me know what you think.
