Did you know NASA Ground Control will be tracking Artemis II via the digital mode FT-4 once they go into earth orbit!

The weak signal condition digital protocol makes it perfect for this purpose.

FT-4 cycle time of 6 seconds is less than FT-8s 15. Combined with the approx. 2.5 second round trip time each transmission will take approx. 8.5 seconds.

That's pretty amazing for Amateur Radio!!

@bernat I see FT4 all the time with my SDR, but I haven't found an app on Windows to decode it yet. Any recommendations? I don't have any aspirations of tracking rockets, but it'd be nice to see where they're coming from.

Hiya @eighthourlunch the "standard" WSJT-X application will decode it - https://wsjt.sourceforge.io/wsjtx.html

There's a dropdown in the UI to select what mode to decode.
