Chris,
With D4.exe turned off, have you checked your PC clock to see if it is gaining
or loosing time? Do a manual sync them wait 10 minutes and do another manual
sync. Then hover your mouse pointer over the Dx.exe icon in the lower right
toolbar. It should indicate the delta time from the last sync.
One thing I noticed which adversely affected my PC clock time. When I use the
PC mouse roller up or down while scrolling through documents or websites in my
browser, the PC clock time slows down.
I've been continuously using D4.EXE since a few years after its introduction in
1995. I've had no issues with it except when a server goes down. I've been
using 'time.nist.gov' which has been super reliable for years.

Hello Chris, Hello Tim
ntp time sync goes like this:
---
your PC sends local time t1 to ntp
time t2 arrived at ntp:
local time t1 + delay client to ntp ( = upload delay) - offset
ntp sends correct time t3
time t4 arrived at PC:
ntp-time t3 + delay ntp to client ( = download delay) + offset
expectation: up/down delay is the same. no jitter!
time t4 is the time to set the correct time at PC
Conclusion: delay for 'up' and 'down' must be the same.
No jitter is allowed on both legs.

Had a similar problem like yours using an ADSL line. The ADSL modem
had apparently some hick-ups (?) resulting of delays from time to time.
Using a utility, like Dimension4 seems to be not a good solution in
such case. Dimension4 connects to just one ntp server all the time.
If you having no decodes - dont' force sync etc, check immediately at
https://time.is/ to verify your local PC time. If your time is way
off, try Meinberg software.
Install Meinberg software and all will be good. During setup enter
your regional ntp pool server.
Ntp pool can be found here: https://www.pool.ntp.org/zone/north-america
Meinberg (free) software:

Tim, Mike,
Well this happened again. FT8 just stopped decoding.
I checked and jt9.exe was still running.
I looked at the time and everything appeared OK,
But I hit the sync time function in Dimension 4 and
Everything started working again.
So even through you can’t see it, this is apparently a time sync issue.
It is a new Dell 6400, Windows 10 and I am running the Dimension 4 v5.31 sync
software.
A manual sync appeared to fix everything.
Thanks for all the support.
This is a great product, please keep up the fantastic work !
