Thanks, Alan. The PC clock here is correct usually to within the millisecond:
The plot has 0.5 ms added to the measured value as MRTG doesn't plot negative
values. The PC has NTP running with a local PPS feed.
I have a rather high local noise level here, so perhaps my impression that WSPR
was more robust than FT8 was mistaken.
