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!!
