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

En VFO:s frekvens beror på matningsspänningen
Ändrar transistorernas arbetspunkt
\rightarrow Stabilisera matningsspänningen
\rightarrow Matningsspänning oberoende av andra steg
\rightarrow Matningsspänning väl filtrerad och frikopplad

Dålig spänningsstabilisering \rightarrow pulsartade frekvenshopp
Särskilt vid nyckling av en sändare
Hos CW-signaler låter det som ett kvittrande ljud i början av tecken \rightarrow chirp
