New PC, clean install of Win 10 Pro (1709 / 1803) Meinberg installed, time checked using time.is web site. On my other PC (Intel i5 NUC) consistent "your time is exact" response. On the new PC (Dell Optiplex i7 32GB 250 GB SSD) I'm getting a consistent "your PC is 0.6 seconds slow. I don't think that 0.6 seconds will have any impact on FT8 or JT65, but why the error? Would switching to "D4" be a better choice?
