New Version 3.1 is Now Available for Windows 10!

Proplab-Pro was one of the first ionospheric physics-based HF radio signal ray-tracing engines in the world for the PC, and has been maintained and developed for over 30 years. It continues to be used by research organizations, scientists, engineers, students, the military and amateur radio operators around the world. It is one of the only software packages to reliably predict ionospherically refracted HF radio signal behavior. It uses both three dimensional models of the ionosphere as well as three dimensional topographical data of the Earth to provide unprecedented detail in modeling HF radio signal propagation worldwide.

Windows 10 Users – Please NOTE

Proplab-Pro does not recognize the magnification capabilities of Windows 10 (yet). As a result, if your Windows 10 is set to enlarge the text beyond 100% (for easier reading), some clipping of the visible areas of Proplab-Pro’s windows might occur. We plan to address this in upcoming releases.

Until then, you can resolve the issue by setting Windows 10 to use 100% magnification. You do this by clicking on the Windows icon in the bottom-left of your screen and typing in “Make everything bigger”. When you click on this, it will open a Display window. Under the Make Everything Bigger heading is a drop-down menu that will let you change the magnification to 100%. Do this and then re-run Proplab-Pro. All of the windows should now appear normal and not be clipped.

APPLE USERS Running Proplab-Pro under Parallels

The issue noted above (screen-clipping of the software) is also a problem for those running Proplab-Pro under Parallels on Apple machines.

To correct the issue, there is a setting in Parallels under:

  • Windows 10 > Configure > Graphics

If you change the setting there from “Best for Retina Display” to “Scaled” (which is recommended for legacy apps), Proplab-Pro will display properly. Shout-out to Richard for telling us how this is solved under the Apple operating system.
