Change log

Newest changes first. Each entry with date, time and — where useful — a link to the affected page.

  1. 20.09.2026, 02:35
    Overview page: tile order reworked — Regions, Prefixes & patterns and Age pyramid first, then all curiosities pages (Cabinet of curiosities, II, III); the rest still follows most-recently-updated. The age pyramid page had no tile of its own before. See the overview →
  2. 20.09.2026, 02:15
    New "Traffic stats" page (far right of the callsign section): page views per day/week, a live view of the last 2 hours, and top pages — under deliberately strict privacy rules: no IP address, no cookies, no external analytics script. Referrer hostnames are clickable, external sources marked with an "opens externally" icon. See the traffic stats →
  3. 20.09.2026, 01:30
    First-name breakdown: two new views "Presumed female first names" and "Presumed male first names" (up to top 150 each, from 10 nationwide mentions) — a purely statistical word match against common name lists, unrelated to gender-neutral language. See the first-name breakdown →
  4. 20.09.2026, 01:20
    Top first names and top street names of radio amateurs each expanded from 50/100 to 150. See the page →
  5. 20.09.2026, 01:10
    Special-event callsigns now link directly to QRZ.com (new tab, marked with a link icon). See the special-event callsigns →
  6. 20.09.2026, 01:00
    New "Making-of" page: how this project came to be — from the first research through the switch from ChatGPT copy-paste to real source control, up to where it stands today. See the making-of →
  7. 19.09.2026, 02:00
    Federal-state stats now switch between two views: "Count" shows absolute license numbers, "Per capita" shows density as "1 in N residents" per state — the smaller the number, the more ham activity there. Also: the old map page is offline for now since the old concept wasn't working. See the federal-state stats →
  8. 18.09.2026, 23:35
    The feedback invitation now appears in the header of every callsign-analysis page (previously only on the overview): "Feedback, wishes, found a structural error? Or want an analysis of your own? Feel free to reach out" with a direct mail link to alexschweigert@gmail.com. See it on the overview →
  9. 18.09.2026, 22:45
    "Cabinet of curiosities" page: the three suffix-length sections (six/seven, five, four characters) now sit right at the top, directly below the key figures — previously further down the page. The first heading now reads "The longest suffixes: six and seven characters" (instead of just "The longest") so it's immediately clear what it covers. See it at the top →
  10. 18.09.2026, 22:25
    "Cabinet of curiosities" page: below "The longest" (suffix length 6+7, 12 callsigns) two new sections for the tiers below it — suffix length 5 (12 callsigns, incl. SCOUT, CRACY, SEVEN) and suffix length 4 (31 callsigns, mostly club/event abbreviations like BBQ, RIG, NRW) — each complete with QRZ.com links. See the new sections →
  11. 18.09.2026, 22:05
    "Cabinet of curiosities" page: six callsign lists (palindromes, triple letters, suffix = prefix, alphabet runs, the longest, the DC1AS neighbourhood) now state directly that they're complete lists (with a count) — previously it wasn't obvious at a glance that nothing was missing. See the page →
  12. 18.09.2026, 21:40
    "List types" page: all six expandable blocks under "Each list by federal state" (personal stations, training, club stations, special events, repeaters/beacons, experimental) are now expanded by default instead of just the first one. See the List types page →
  13. 18.09.2026, 21:30
    "Three assignment epochs": the per-prefix comparison below it (16 nearly-all-grey bars, barely readable) was replaced with a real timeline from 1949 to today. Three rows (Class A/E/N) with two dashed markers (1997, 06/2024) show at a glance since when each class could even be issued — instead of a barely distinguishable bar list per prefix. See the timeline →
  14. 18.09.2026, 21:14
    The "Estimated license age" section was completely rebuilt as "Three assignment epochs": now makes clear this was never about the current holder's age (that's the first-name pyramid above), only about the callsign as a character string. New: three large epoch tiles (Class N since 06/2024, Class E since 1997/2005, Class A undeterminable) instead of two percentage cards; the per-prefix bars below stayed the same data, just renamed throughout. See the rebuilt section →
  15. 18.09.2026, 21:00
    QRZ.com links now phrased more honestly: the tooltip no longer promises a profile, it now says "Look up ... on QRZ.com (if a profile is listed there)". Reason: not every callsign has an account/profile there, and checking all ~70,000 callsigns by scraping is explicitly against QRZ.com's terms of use. See an example →
  16. 18.09.2026, 20:51
    All QRZ.com callsign links (Curiosities II, Curiosities, Special stations, Prefixes) now show a proper "opens externally" icon (square with an arrow to the top right) instead of the plain ↗ character — including in the nerd theme, where it was previously hidden entirely. See an example →
  17. 18.09.2026, 20:42
    "Knowledge & legends" page: the expandable lists "First names in the suffix" (25 names) and "Animals, cars, everyday life — words in the suffix" (30 words) are now expanded by default instead of needing a click each. See the Knowledge & legends page →
  18. 18.09.2026, 20:37
    "Estimated age pyramid" page: new section at the bottom — estimated license age by prefix (Class A/E/N counted directly from the BNetzA list, no first-name approximation), with a warning about §11 AFuV reissuance and prefix DN as an example of three overlapping regulatory eras. See the new section →
  19. 18.09.2026, 19:45
    Renamed the "Aging in amateur radio" page to "Estimated age pyramid in amateur radio" (softer wording), nav button changed from "Aging" to "Age pyramid" accordingly. See the age pyramid page →
  20. 18.09.2026, 19:35
    Switched the whole site's default language from English to German (home page, About, logbook/QSL pages) — English is still available via ?lang=en. The callsign analysis was already German by default.
  21. 18.09.2026, 13:10
    Cabinet of curiosities & special stations: every individual callsign shown (palindromes, triple letters, ham vocabulary, shortest/longest, club stations etc.) is now linked to QRZ.com (opens in a new window) — as already done for prefixes and "Facts & legends". See the cabinet of curiosities →
  22. 18.09.2026, 12:05
    Cabinet of curiosities: the "Ham vocabulary in the suffix" and "The shortest: one letter" accordions now open by default instead of collapsed. See the cabinet of curiosities →
  23. 18.09.2026, 11:40
    Prefixes & patterns: the "Each prefix by federal state" accordion — all prefixes now open by default instead of collapsed. See prefixes & patterns →
  24. 18.09.2026, 11:10
    Age pyramid: fixed the intro text for "Six generations, roughly classified" (the basis is now 100 first names, not 22), and added the 10 most common example first names with peak popularity in that period, per generation. See the age pyramid page →
  25. 17.09.2026, 19:30
    New "Aging in amateur radio" page (today: "Estimated age pyramid") went live: first names by birth year, license numbers since 1933, local clubs, and an (explicitly speculative) age pyramid with a counter-check via the new Class N license — all in one place, with open methodology instead of quick claims. See the age pyramid page →
  26. 16.09.2026, 20:17
    Curiosities III: moved the generations section to the top, split "from 1975" into Gen X and Millennials & Gen Z (now 6 steps), with up to 9 example first names per step instead of 5. See Curiosities III →
  27. 16.09.2026, 20:08
    Curiosities III: expanded the generation analysis from 3 to 5 finer steps (early post-war, economic-miracle generation, late post-war, baby boomers, Gen X & younger), each step with at least 5 example first names. See Curiosities III →
  28. 16.09.2026, 20:01
    Curiosities III: expanded the street name list from top 50 to top 100. See Curiosities III →
  29. 16.09.2026, 19:56
    Curiosities III expanded: a generation analysis of the top 50 first names ("why Klaus and Wolfgang still beat Kevin and Justin"), a rough gender estimate based on first names, and a cross-check of the real top 50 first names against the first-name easter eggs in the callsign suffix. See Curiosities III →
  30. 16.09.2026, 19:36
    Curiosities III: removed the "Doctorate and professorship titles by federal state" section and the Prof. metric. See Curiosities III →
  31. 16.09.2026, 19:33
    Curiosities III: first-name and street-name lists expanded from top 20 to top 50. See Curiosities III →
  32. 16.09.2026, 19:31
    New "Curiosities III" page: top-20 first names and street names, most popular house numbers, Dr./Prof. share by federal state — all as nationwide or state-level totals only, with no link to any callsign or ZIP. See Curiosities III →
  33. 16.09.2026, 19:02
    Regions: Page title simplified to "Number of amateur radio licenses by federal state & ZIP". See the regions analysis →
  34. 16.09.2026, 18:46
    Regions: In the ZIP-3 lists, the city/region name now leads large and bold, with the ZIP code small underneath — it was barely legible before. See the regions analysis →
  35. 16.09.2026, 18:39
    Regions: The ZIP-3 lists (top 50 nationwide & top 25 per leading digit) now show the city or region for each area — e.g. "381xx · Braunschweig". See the regions analysis →
  36. 16.09.2026, 17:56
    Regionen: Unterüberschriften der Postleitzahlen-Auswertung nach Anfangsziffer prägnanter gefasst (z. B. „0xxxx · Top 25“). See the regions analysis →
