  2. Seeing a Lot of Skipping Decodes Every Other Sequence FT8

Bill,
Just a quick note in case you did not get my email to you.

It has been 12 hours and no failed WSJT-X decodes with the following arrangement:

WSJT-X UDP 2237
JTA 2237 (automatically found I think)
JTA Rebroadcast: 2337
SpotCollector Enable WSJT Port 2337 as a Spot Source in its config file

12 hours on 20 meters is a lot of decodes. I provided more information w/r to this in my email. I'll continue to let it run and see what happens.

This is what I've learned so far:

Start WSJT-X first, then JTAlert, and SpotCollector last.

All 3 programs work. JTAlert fills with calls. SpotCollector is populated with WSJT-X decodes. Do not double click on any callsign in SpotCollector

As long as I use either WSJT-X itself or JTAlert to do frequency changes and initiate calls, things continue to work.

If, on the other hand, in this current arrangement, I double click in SpotCollector on a call, it definitely gums up the works.
73, N0AN

Markku,
If  you start Task Manager in Windows, you will see that Spot Collector, unfortunately, is a very heavy user of CPU power.  It is, most likely, the cause of your problems.  I am a devoted user of DXLab, but I rarely use Spot Collector any more.  I use other spotting resources that do not place such a heavy load on my CPU, an I5-6500.

This problem has been discussed before, and I'm one of these with problems. But I'm not using JTAlert, but DXlab with Spotcollecter and DXKeeper. The Spotcollector also communicate with WSJT, like JTAlert.

I think this problem is caused by exhausted Windows resources. If I move a window, decodes are often skipped. Sometimes Windows is doing something cpu intensive in the background (look at the processlist), and decodes are skipped. Or some other software is updating in background, like the antivirus program.

I have given up and accept some missed decodes. Maybe if I had a faster PC, the problem would be solved. I don't know.
