6m QRP FT8 (Sunday)

My 6m FT8 gear (2.5W to a V2000 vertical omni) was turned on about 0940z. So far, absolutely nothing on RX or TX. I would have expected some activity on a Sunday morning if only a few local Gs. I checked that everything was correct: timing, SWR, frequency, antenna, co-ax,  WSJT-X restarted etc.   As far as I can tell, all is fine.
