Just managed my 1st FT8 contact on 70cm. Using a 6 element portable Yagi/Uda on a wooden airer in the room and 25 Watts. G4YTL was using a bit more power and an external aerial.
Initially there was a lot of aircraft scatter, which meant that decoding was a problem, but a couple of good steady bursts and we completed the contact. Only 132kM, but good for a start. I'll upload a screen shot so people can see just how much the aircraft scatter was drifting the signals.
