What flies past your antenna
A station page could already describe a receiver as hardware — uptime, day streak, typical range, the shape of its horizon — and, since this week, what it put into other people's collections. What it still could not tell you was the thing you actually stand at the window wondering about: what flies past this antenna.
It can now. Every station page with enough history has a Types tab: a wall of aircraft models, drawn as the same cards the game uses everywhere else, with the receiver's own numbers on each one.
Two numbers, because one would lie
Each card carries airframes and sightings, and the whole reason the tab exists is that these are different facts.
Airframes is how many different machines of that model this receiver has heard. Sightings is how often any of them turned up — one per airframe per UTC day.
Sixty different A320neos, each heard once, is an airway passing overhead: a river of strangers. One Cessna heard sixty times is the flying school down the road. Both would read as "seen 60 times" if we collapsed them into a single counter, and you would have no way to tell the two skies apart. So both numbers are printed, on every card, and the tab says in plain words what each one means.
We do not call sightings "flights". A receiver has no idea where one flight ends and the next begins; a day-count dressed up as a flight-count would be a number we cannot stand behind. Alongside them sits the observed window — the sampled time one of those aircraft was in view — which is called observed and never flight time, for the same reason.
The wall also prints its own denominator. Models are only known for the airframes we have recorded a type for, and we only started recording those on 1 September. Everything heard before that still counts towards the station's totals; it simply cannot appear on a wall of models. The page says so rather than quietly showing a smaller sky.
A collection page that knows you run a receiver
The second half of this is on your own collection. If you feed the network, your aircraft page now opens with a 📡 row that nobody without a receiver has: models heard, airframes heard, sightings, observed time, and — the interesting one — how many models your hardware has heard that you have never actually caught. That last number is a to-do list.
On the cards themselves, the antenna's count has moved out of the subtitle, where it was being cut off mid-number by the ellipsis, and onto its own pill under the rarity ribbon: ✋ what you caught, 📡 what your receivers heard.
Those two never merge into one total, and they never will. Add them together and anyone with an antenna out-collects anyone with a camera while asleep, which would quietly make the shutter pointless. Hardware and a shutter are different work. They get to sit side by side on the same card and stay themselves.
