I've now been running WSPR on a RTL dongle 24/7 with SDR Console 3.0.25 b1990/WSJT-X/Mushzenco for about 10 days.
DT has not risen at all.
However, before that with an identical test DT rose to a few seconds overnight. It was not computer timing, other instances of WSPR were unaffected. They run for weeks between M$ updates.
I can not explain but it seems there can be intermittent problems with this setup.

It's the difference in clocks between the SDR and PC, as simple as that. I'll explain later about a VAC trick I have enabled which we should disable for WSJT. Am now back firing on all cylinders.
