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

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.
