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

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 !

Hey Chris, I've had something similar happen... Basically all stations fail to 
decode. 
Check your clock. Make sure NTP is synced. I have a Dell laptop that 
continuously slips so I force it to resync before I start pulling my hair out.

When that happens check if jt9.exe is still running.

Hi Gary
 
Just thought I would let you know I have had this happen 3 or 4 times now.
 
Just since 1.9.1 the system just stops decoding even though the stations appear 
on the waterfall.
 
Nothing happening that  I can relate to this, it just happens once in a while.
 
It takes a complete shutdown reboot to correct this. A restart doesn't help.
 
I am Windows 10 release 1803, Signallink SL-1+ to an FT-847
 
Have you heard anything else about this issue ?
What might be causing it or any correction?
 
Thanks

I had this happen a couple of versions back, but that was the only time.  If 
you aren’t operating but just in monitor mode continuously, does it do the same 
thing?  I monitor 24/7 except when storms are in the area and have not had a 
problem, even since the 1.9.1 version was released.  It’s pretty strange to 
have the waterfall showing signals, but all of a sudden nothing is appearing in 
the decoded windows, but I have see it so I know it does happen.  You are not 
the first to report this recently, but it sounds like it is kind of rare.
