live over Orlando — aircraft on 1090 & 978 MHz, MCO tower & approach audio, Orange & Osceola fire/EMS, and airline datalink, received at home in Lake Nonawhat's overhead, in plain words →
Where it goes: aircraft positions (1090 MHz ADS-B, plus 978 MHz UAT from light aircraft) are shared with FlightAware, Flightradar24 (T-KMCO49), RadarBox, Plane Finder, OpenSky Network, ADS-B Exchange, adsb.fi, adsb.lol, airplanes.live, Planespotters and AeroDataBox, with MLAT on the community networks. Airline datalink (ACARS and VDL2) goes to airframes.io as CLIPPERMIKE1-VDL2.
The hardware: two small Linux boxes and eleven SDR receivers. The main box runs nine: 1090 MHz ADS-B, ACARS and VDL2 datalink, two airband receivers for MCO tower/approach/departures on VHF dipoles, and four on the Orange and Osceola P25 trunked radio systems. A second box has its own 978 MHz antenna for UAT.

What this is: radiosondes are the small expendable weather balloons the National Weather Service (and hobbyists) launch daily; each carries a GPS/telemetry transmitter around 400 MHz. This station decodes them with radiosonde_auto_rx and uploads to SondeHub as skyking-403. A flight is logged here only once it has been decoded directly by this station — not just seen nearby by someone else's receiver. Temperature and battery voltage are reported by some sonde types (DFM, RS41) but not others (LMS6). Click a sonde type for a fact sheet on that model, or the balloon # to open its track on SondeHub. Launch site is a best-effort guess — the nearest known NWS upper-air station to the flight's earliest received position. A flight still in the air shows as a pulsing LIVE card above, updating every 30 seconds while it's tracked.

What this is: Russia's Meteor-M2 weather satellites (M2-3 and M2-4) fly over twice a day each, about 500 miles up, and send their pictures down live on 137 MHz. A small antenna on the porch roof catches them and SatDump turns the radio signal into an image. Daytime passes are shown in colour; at night the camera still sees heat, so those are infrared (white = cold cloud tops, dark = warm land and sea). The house blocks part of the sky, so most passes give a strip rather than a full frame — the higher the pass (degrees above the horizon), the more we get. Click a picture for full size; arrow keys step through them.
How to use this page
Everything here is received live by a small home radio station in Lake Nona: aircraft, MCO air traffic control, Orange and Osceola fire/EMS radio, and airline text messages.
PANEL BUTTONS
▾ hide folds a panel down to its title bar. Press it again to show it.
⤢ expand fills the screen with that panel. ← back or Esc returns. Tapping a panel's title does the same.
⧉ pop out opens the panel in its own window, which you can move or resize (another monitor works well). Close that window, or press bring it back, to return it to the page. Computers only.
The bar along the bottom of a panel can be dragged to make it taller or shorter. Double-click it to reset. Your sizes are remembered on this browser.
THE MAP
A plain mouse wheel scrolls the page. Hold Ctrl and scroll to zoom the map (inside an expanded or popped-out map the wheel zooms normally). On a phone, tap the map to use it and press lock map to scroll the page again.
Click a plane, or a row in the table, for its details: type, route, altitude, speed and photo.
Drag the grey bar between the map and the table to give the table more room. Double-click it to fit the table to its columns.
Row colours: heard directly from the aircraft · light aircraft on 978 MHz (UAT/ADS-R) · MLAT, a position worked out by timing the signal at several receivers · TIS-B, relayed by the FAA from its radar: planes without ADS-B, and airliners on the ground at MCO whose own signal is blocked by the terminals (their row flickers between colours) · transponder heard but no position. A row's colour follows its latest update. A bright red row is an emergency squawk.
Distances are in nautical miles (1 nm = 1.15 miles).
LISTEN (THE SCANNER)
Press START SCANNING once. Browsers won't play sound until you click something. Then use the buttons to switch between MCO Airband, Orange County, Osceola County, or Combined.
Silence is normal: you only hear it when someone is transmitting. The audio runs a few seconds behind real time.
An amber DISPATCH TONE banner means fire/EMS alert tones just went out, and a dispatch is about to follow.
The little i bubbles explain Squelch and Hang time.
ACARS
Text messages between airliners and their airlines: gate assignments, weather, fuel, delays, and now and then a fault report. readable shows the ones written for people; all shows every machine message too.
STATION
Live counts from the receivers, plus today's totals and the farthest aircraft heard today. Everything received is also shared with flight-tracking sites (listed in that panel), which is how FlightAware ranks the station.
RADIOSONDES
Weather balloons this station has decoded directly, with all-time records (farthest range, highest altitude, longest tracked flight) and a log of recent catches, including temperature, battery and SNR when the sonde type reports them. Fed by SondeHub.
SOMETHING NOT WORKING?
Pop out does nothing: your browser blocked the pop-up. Allow pop-ups for clippermike1.ddns.net, then try again.
No sound: press START SCANNING again, or reload the page. On an iPhone, check the silent switch.
The table is squashed or too wide: drag the grey bar next to it, or double-click that bar.
A panel is the wrong size: double-click the bar along its bottom edge.
