Weather and FIS-B
The Weather page displays FIS-B products received over 978 MHz from FAA ground stations when reception is available.

No current ground station or weather product is being received. Coverage depends on location, terrain, antenna placement and ground-station availability.
Formal IFT-01 field validation of FIS-B weather reception remains pending. Never assume the Weather page contains complete or current weather. Confirm critical weather through approved aviation sources.
GPS placement and states
Place or move IFT-01 where it has a clear view of the sky. Buildings, roofs and some aircraft structures can delay or prevent a fix.
An indoor No Fix condition is normal. Place or move IFT-01 where it has a clear view of the sky and allow time for acquisition.
