Radio Propagation

And here we see the fly-through with the 10m band added to the mix.

Here's the 2D version as rendered by LiveMUF.

Radio Propagation

Sporadic-E clouds over Eastern Europe have raised the MUF towards 100 MHz.

Here we see 6m Es and 2m tropo spots in 3D.

Radio Propagation

3D fly-through showing 10m and 6m propagation between South and North America, recorded just now.

The orange clouds (which are drawn a bit too bright!) denote zones of signal refraction for TEP (Trans-Equatorial-Propagation).

Space Weather

Aurora reported by amateur radio operators down to ~50ยฐN over Europe.

A G1-G2 geomagnetic storm is in progress.

Radio propagation on HF has taken a hit at the higher latitudes thanks to the storm.

Radio propagation visualised in 3D! Two examples of auroral propagation on the 2m band caught on my Ionospheric Path Monitor just now.

Radio Propagation

The VHF/UHF FT8 Activity Contest kicked off at 18h UT. 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 (author of LiveMUF) is one of the contacts seen in this video (at the bottom end of Cornwall).

Radio Propagation

My Ionospheric Path Monitor has been adjusted to plot chordal hops correctly using accepted physics. Signals across the equator usually stay airborne for a considerable distance before coming back down to earth.

New orange "glow zones" show the potential zones for the airborne reflections from the ionosphere at around 400km altitude.

Radio Propagation

It's the evening in Australia and Japan, early morning in Western Europe. This is what the 10m band is doing right now, based upon DX CLuster reports.

Radio propagation visualised!

Radio Propagation

The 10m and 6m bands now have openings between Europe & Middle East to S America, and USA to S America, but the higher bands are fading as the sun sets.
