You need to LOGIN to send your report! Refractive index forecast for Europe provided by Pascal, F5LEN. org website 144 MHz Map: At Rabbitears. Tropospheric bending extends the range of radio & TV stations well beyond their normal limit and thus increases interference amongst stations as well. Jan 24, 2023 · Radio propagation: Good tropo conditions are currently extending VHF/UHF range across northern parts of Europe. This is different from topography-conforming Radiation Tropo in that the inversion can persist all day long, long after any radiative effects have dissipated. Sudden changes in the atmosphere’s vertical moisture content and temperature profiles can on random occasions make microwave and UHF & VHF signals propagate hundreds of kilometers up to about 2,000 kilometers (1,300 mi)—and for ducting mode even farther The UK Six Metre Group .

From Wikipedia about tropospheric radio propagation:. Archiving of maps is not permitted, except for the occasional map used for documenting significant ducting events. The "Tropo Forecast" is updated daily at 1700 UTC. Sudden changes in the atmosphere’s vertical moisture content and temperature profiles can on random occasions make microwave and UHF & VHF signals propagate hundreds of kilometers up to about 2,000 kilometers (1,300 mi)—and for ducting mode even farther "Hepburn Tropo Index" "The Hepburn Tropo Index is the degree of tropospheric radio wave bending forecast to occur over a particular area, which is an indication of the overall strength of tropospheric radio signals (and hence interference) on a linear scale from 0 to 10. Many thanks for making this The tropo forecast is looking good for the south of UK this weekend. Let's hope the tropo comes good midweek and some of us manage to make a contact via FT or phone modes.
