Ionaut — Ham Radio

Sporadic-E — new module Shows where Es clouds are standing right now. Three readings sit side by side and are deliberately not stirred into a single number, because they say different things: what was actually reported in the past hour, what the ionosondes measure, and what the season would lead you to expect. Real reports beat any calculation — the sonde only decides where nobody has been on the air. Reports on 2 m and 4 m only count as Sporadic-E if a 6 m cloud stands at the same place and time. An E layer that carries 144 MHz carries 50 MHz easily; the reverse does not follow. On 10 m the result is cross-checked against the F2 layer, so an F2 opening is not mistaken for Sporadic-E. Formula reference in the calculator The official German formula reference for the amateur radio examination, complete and properly typeset rather than photographed: fractions as fractions, roots with a radical bar, subscripts where they belong. From every section you jump straight into the matching calculator. Reproduced by permission of the Bundesnetzagentur. Widgets rebuilt Every view has been redesigned from scratch and now follows one shared layout. New: Sporadic-E with a radar view centred on your own location, and a DX view showing every world region at once, sorted by where you can reach right now. Space weather gives the space to the bands instead of two bare numbers, and Grayline draws a 24-hour day/night strip. Large widgets are supported for the first time. DX cluster with history The spot list used to reach back about twenty minutes. It now covers close to three hours. Licence classes The per-country notes have been reviewed and tidied, and the English texts are now complete rather than patchy. Albania had the wrong unit on 40 m (MHz instead of kHz) — corrected. Also - iPad: world map in the correct aspect ratio, time axis no longer wraps - Translations refreshed across all 44 languages - Many labels made consistent
