ACURA 3D ham radio propagation globe showing worldwide HF radio signal paths, amateur radio communications, and global propagation.

3D Propagation Globe

Our 3D propagation globe shows where ACURA members are being heard around the world right now. Each glowing arc runs from South Jersey to a station that copied one of our members in the last 24 hours. The colors show the band, and the day and night sides of the Earth move in real time, so you can watch the gray line sweep across the planet.

How the Propagation Globe Works

Digital modes such as FT8, FT4 and WSPR send automatic reception reports to PSKReporter. Our server collects the reports for every member on the club roster, and the globe draws one arc for each. Because the globe shares its data with our Who’s Hearing Us map, it updates every few minutes without overloading PSKReporter.

Tips for Exploring the Globe

First, drag the globe to spin it, and scroll or pinch to zoom in. Next, tap a band button to hide or show that band, or pick one member from the list. Then point at any arc to see who heard the signal, how strong it was and how far it traveled. Finally, press Show the sun’s side to see which part of the world is in daylight.

Get Your Signal on the Globe

Your signal shows up automatically once you are on the ACURA roster and you transmit on a mode that reports to PSKReporter. FT8 on 20 or 40 meters is the easiest place to start. Also, compare your paths with the day and night line on our Gray Line Map, because many long-distance openings follow the gray line.
