SuperminarenandClaude Sonnet 5.5 f7fa8cfbc1 Swedish adaptation: Instegscertifikat and HAREC content
- Sections and slides rewritten in Swedish; German law and institutions replaced by
  Swedish/CEPT/ITU equivalents (PTS, SSA, PTSFS 2025:1, SSMFS 2008:18), unverified
  statements marked "% TODO VERIFY"
- New toc: INSTEG, HAREC, UPPGRADERING; section idents are Swedish (see ident-map.tsv)
- Exam-question tags, BNetzA question pool, solutions and the German SWL course removed
- Static pages, snippets, applets, READMEs and image alt-texts translated
- TikZ labels translated; SVG drawings regenerated (drawing 689 still fails to build
  upstream: it references a missing photo)
- Changed from the original: not endorsed by DARC e.V., SSA or PTS

[picture:470:a_lnb:Blockschema över en mottagargren med LNB] * *Low Noise Block Converter* (LNB) blandar ned höga frekvenser direkt efter antennen * Vanlig vid satellittrafik * Lägre kabelförluster tack vare lägre frekvens
[picture:470:a_lnb:Blockschema över en mottagargren med LNB] * Behöver matningsspänning * Bias-T används * Olika spänningar för olika polarisation * Vanligen $\qty{12}{\volt}$ och $\qty{18}{\volt}$
