Estimated age pyramid in amateur radio — the full investigation

📊 The situation in four numbers

🔺 The age pyramid (first-name approximation)

The same six generation steps as above, but no longer as six coarse blocks: each is spread as a bell curve around its estimated mean age, the curves are added up and then scaled so the total matches the real total stock of roughly 70.009 radio amateurs — not just the first-name-detectable sample of roughly 33.933. Result: a pyramid in real 5-year age steps that naturally thins out toward the top, down to a handful left around age 100. Important caveat remains: the basis is still first-name frequency, not real birth dates — and modern, diverse first names are harder to capture than the few dominant names of earlier decades. The lower steps are therefore probably wider than shown here (see the Class N counter-check below).

📡 The counter-check: Class N against the total stock

The pyramid above rests entirely on the first-name approximation. There is exactly one figure on this page that does not: the license class. Class N has only existed since 24 June 2024 — every Class N holder got their callsign within roughly the last two years. That is not proof of age (older newcomers can pick Class N too), but it is a real, official signal that new people are joining right now, independent of any first-name estimate. Class E, by contrast, is a poor comparison: it traces back to the old Class 3 introduced in 1997 and was merely renamed in 2005 — a Class E callsign can just as easily be 25 years old as one month.

The Class N bar is drawn to scale against the total stock: roughly 1,70%. Small, but exclusively new: a real sign of life that the first-name pyramid above cannot show.

🕰️ From the very beginning

Amateur radio in Germany is almost as old as the broadcasting era itself. Nearly a hundred years lie between the earliest transmit licenses and today’s complete official annual statistics — with one long gap for which only scattered dates exist, not a continuous series (see the chart further down).

• 1933From August, the Deutsche Reichspost issues the first 180 transmit licenses for radio amateurs.
• 1939The number of amateur radio stations grows to about 600 by the start of the war.
• 1949On 23 March, the young Federal Republic issues the first 700 post-war licenses.
• 1950–1999There is no continuous official yearly series for these five decades — only a few documented dates (1954, 1962) and an explicitly marked estimate in between, see the chart below.
• 2002Peak of the official statistics: 80.874 individual licenses.
• 2024The new, low-barrier Class N license is introduced — a targeted attempt to attract young newcomers.
• 202561.105 individual licenses — a decline of 24.4% since the peak, with an almost uninterrupted downward trend.

📉 The license trend since 1933

The solid line (2000–2025) comes directly from the Bundesnetzagentur’s annual participant statistics (as of 31 Dec each year, "number of amateur radio licenses" column) — no first-name approximation, no interpretation. The dashed line before it connects four actually documented historical dates (1933: 180, 1939: 600, 1949: 700, 1954: 3,389 — the latter per the German Wikipedia article "Amateurfunkdienst") with a single, uncertain secondary-source figure for 1962 (roughly 15,000, per rtc-dl.de — this one source is unverified and states a contradictory figure elsewhere, so read with caution). Between 1962 and 2000 there is no reliable figure at all — the dashed line there is pure geometric interpolation, not a measurement.

Sources: Bundesnetzagentur, "Amateurfunk in Deutschland – Teilnehmerzahlen" (2000–2025); de.wikipedia.org/wiki/Amateurfunkdienst (1954); rtc-dl.de/die-geschichte-des-amateurfunks (1962, uncertain). 1933/1939/1949 as in the timeline above.

👤 First-name research by birth year

For each of the most common first names we researched which decades it actually ranked among the most popular boys’ names in Germany (source: beliebte-vornamen.de, based on over a million birth records since 1890). The bars show the real time span — deliberately overlapping, not assigned exclusively to a single generation. Someone named "Alexander" born in 1968, for example, will find themselves here too, even though the name’s peak popularity came only in the 1990s.

Bars = decades in which the name ranked among the top 50–120 of that decade. Dot = decade of peak popularity. Bar color = frequency among DC1AS radio amateurs (darker = more common). This time travel still isn’t a real age survey — the BNetzA list contains no birth date. From rank 51 on, a few spans are rougher estimates (compound names combined from two parts, "Lutz" unsupported in the ranking lists).

📻 Six generations, roughly classified

Same basis as the time travel above (now 100 researched first names), now grouped into six coarse steps instead of individual names — handy for a quick overview. Below each step are ten example first names whose peak popularity falls in that period (ranges deliberately overlap, see the time travel above).

🔍 Three assignment epochs: what a callsign can actually tell you

Important distinction: this is not about the age of the current holder (that was the first-name pyramid above) — only about the callsign itself, the character string. Since when can it possibly exist? The prefix letter alone says nothing: "DL1xx looks old, so it is old" is a fallacy. Under §11 AFuV, Class A callsigns may be reissued after expiry (death, surrender, non-payment) following a two-year blocking period — a historic "DL1..." from 1952 and a "DL1..." reassigned four weeks ago look identical. The only solid basis is therefore not the prefix but the license class — and that has exactly three epochs. The full prefix time-travel (occupation zones, German division, reunification) lives on the "Curiosities II" page.

Two prefixes tell the most interesting story. DO is 100% Class E — the character string itself cannot have originated before 1997 in this prefix, regardless of the current holder. DN, by contrast, is the only prefix carrying all three epochs at once — 3.943 Class A, 795 Class E and 1.188 Class N under the same prefix letter. DN is therefore a prefix where three assignment epochs literally overlap: undeterminable, reissuable A callsigns next to entry-level callsigns from up to 29 years ago next to brand-new Class N assignments since 2024.

Since when has this even been possible? The timeline

A bar per prefix (16 of them, almost all 100% grey) was barely readable — the real story isn’t in the prefix, it’s in the class itself. So here are the same three classes as a timeline from 1949 to today: each row shows since when that class has even existed or could be newly assigned. Class A spans the whole period — not because every Class A callsign is old, but because none of them can be reliably dated.

How to read this: the further left a bar starts, the longer that class has existed — not: the older an individual callsign within it is. The dashed lines mark the two introduction years (1997 for Class E, June 2024 for Class N). Class A starts at 1949 because that’s the earliest post-war licenses — not because a typical Class A callsign today is that old.

Methodology & sources: a direct count from the BNetzA callsign list by prefix and license class (stats.json, field by_class_detail) — no estimate, no first-name approximation. Class history: Class E, formerly "Klasse 3" (introduced 1997, renamed by the 2005 AFuV amendment, in force 19 Feb 2005); Class N introduced with effect from 24 June 2024 (Bundesnetzagentur Vfg. 53/2024 & 61/2024). Reissuance rule: §11 AFuV (two-year blocking period after expiry). Prefix meaning: BNetzA "Rufzeichenplan für den Amateurfunkdienst in Deutschland", Verfügung 15/2025, valid from 1 April 2025. Prefixes with very small counts (DA, DP, DQ, DR — mostly special and exceptional formats) are included but should be read with caution statistically.

All figures on this page: pure nationwide totals and openly documented model calculations. No individual addresses, no names of individuals, no link to a specific callsign.
