See the contesters on this flythrough over Europe. 2m band contacts are the red lines, and as the contacts are mostly tropospheric, the signals are hugging the surface of the planet within a few km. It's fitting that Dave, G7RAU (and author of LiveMUF) is one of the contacts seen in this video (at the bottom end of Cornwall). #radiopropagation #amateurradio #g7izu

Signals across the equator usually stay airborne for a considerable distance before coming back down to earth.

This time, only the 80m, 40m and 20m bands are selected. We see the lower frequencies, mostly on the night-side of the planet, 10m on the day side. The lower frequencies are refracting from lower ionospheric layers than the higher frequencies do. #radiopropagation #amateurradio #g7izu

The number of hops any particular signal path makes is estimated and not real, but is based upon real factors such as ionosphere height, propagation mode and the MUF. Different frequencies reach different heights, as future videos will show.

This 3D fly-through was created using a new mapping backend for G7RAU's Live MUF that I created. It runs in a web browser is is under test. Similar to the maps on my website, line colour indicates frequency. The coloured blobs show areas of high MUF (sporadic-E clouds). Purple is showing Band 2 FM reception via sporadic-E, yellow is the 10m band. As new spots appear, you see the lines propagating between ground and ionosphere as they bounce around the world. #radiopropagation #amateurradio #g7izu

𝑮7𝑰𝙕𝑼 𝑹𝙍𝑫 (@g7izu@universeodon.com) Attached: 1 video Radio Propagation I made a thing! With the help of Claude AI, I made a new mapping backend for LiveMUF. The entire thing — 3D WebGL renderer, ionospheric physics, signal animation, Es detection, MUF modelling, band matrix, 2D map, live database connection — fits in a single HTML file of about 3,000 lines. No npm, no webpack, no dependencies beyond D3 and TopoJSON loaded from a CDN. A helper file interfaces with the LiveMUF SQLite database and forwards spots to the map as they appear. I'll need to work on a version for MySQL. It currently only runs on a PC which already has LiveMUF installed and capturing spots to a local database. It renders propagation paths in realtime, projecting the signal path via realistic estimated bounce points around the globe. Ionospheric height is correctly rendered. Glowing areas appear at the reflection points and show sporadic-E clouds, coloured according to frequency (but not yet directly linked to the estimated MUF). I'll follow up with more videos. #radiopropagation #g7izu
