During EAA AirVenture 2026 (July 20–26), Wittman Regional Airport becomes the busiest airport on the planet — more than 10,000 aircraft moving through one Wisconsin airfield in a single week. Every one of those aircraft is broadcasting its position, and with the right hardware, you can watch the whole ballet live. This is the story of ADS-B, and why a dedicated ADS-B display like SkyWatch is the centerpiece upgrade for any aviation desk setup.
ADS-B in Plain English
Automatic Dependent Surveillance–Broadcast (ADS-B) is the system by which aircraft continuously transmit their GPS position, altitude, speed, callsign, and type over radio. It's required equipment in most controlled U.S. airspace, which means the overwhelming majority of traffic — from airliners to homebuilts — is announcing itself in real time. Anyone with a receiver can listen. No login, no gatekeeper: the sky, narrating itself.
Why AirVenture Is ADS-B's Greatest Show
On a normal day, ADS-B is interesting. During Oshkosh week, it's cinematic:
- The inbound stream — thousands of aircraft funneling toward Ripon and the famous Fisk arrival, visible as a river of targets on any live map
- Mass arrivals — type clubs (Bonanzas, Cessnas, Mooneys) flying in as large formations
- Showcase traffic — 2026 headliners tied to the America250 theme, including the RAF Red Arrows, NASA's Super Guppy, and the B-29 "Doc"
- The Sunday exodus — the departure wave scattering back across the continent
Whether you're on the grounds or a thousand miles away, live ADS-B is how you see the full picture.
The Desk Setup Upgrade: A Dedicated Radar Display
Most people experience ADS-B through a browser tab. Functional — but a tab gets closed, and a phone gets pocketed. SkyWatch takes the opposite approach: a compact device with a round display that renders live traffic like a radar scope, always on, always in view. Next to your monitor, on the sim rig, in the hangar office — it reads as instrumentation, not another screen.
What sets it apart
- Purpose-built display. A circular screen designed for the radar-scope aesthetic, showing callsign, type, altitude, and heading for traffic around your location.
- Two ways to feed it. Use live cloud flight data over Wi-Fi, or connect SkyWatch to your own local ADS-B receiver (Raspberry Pi + dump1090 setups welcome) for direct, real-time coverage of everything your antenna hears.
- Mode variety. Aircraft is just the start — switch to ship tracking, satellite passes, or live weather radar when the mood strikes.
- No subscription. One purchase, permanent situational awareness.
For the Homebuilder Spirit
AirVenture began as a gathering of people who build and tinker, and SkyWatch fits that DNA. If you already feed ADS-B data from your own antenna, pointing SkyWatch at your local feed gives you an unfiltered picture of your airspace — including low-level traffic that never makes it onto the big aggregator sites. It's the difference between watching someone else's radar and running your own.
Set Up Before the Show Starts
The AirVenture 2026 build-up begins days before the gates open on July 20. Get a SkyWatch on your desk now, and you'll watch the migration form, track the week's traffic live, and keep a working radar scope in your setup long after the last warbird heads home.
