SmartSDR CAT losing connection with WSJT-X instance

Read in another thread that this may be an issue with TCP/Hamlib method.  Recommendation is to go back to Kenwood 2000 using Com ports.

The Flex related problem with hamlib was fixed in WSJT-X about a year or so ago.  If you are running wsjt-x 2.1.2 there should be  no hamlib problems with flex.  I have not had any CAT problems related to the hamlib bug when using wsjt-x 2.1.2.

Sounds to me like a network issue.  How are you connecting to your network?

Not an issue....if it was I would see it while operating.  Checked network config setting and there are no sleep issues.  Computer to radio latency is, while operating, 1 to 3 ms. 

Patrick

Latest versions of all the apps I am using.  I use the Flex 6000 on port 5002 and CAT for PTT.  works fine...... I feel that SmartCAT is just not robust enough, and needs further refinement.  Nothing’s perfect.....

This morning 3 out of 4 instances of WSJT-X had disconnected from CAT, ver 2.1.2 TCP method. Changed over to COM ports, see what happens. This is a very recent experience for me and nothing has changed on my computer. Been running SSDR 3.1.8 for some time now.

I assume each instance of WSJT-X has its own unique TCP port ?

Yes Al, can not imagine what has changed to cause the loss of CAT connection over night. Radio is on Static IP and PC, Radio & Amp are on 5 port switch which are powered by UPS. Have reviewed Event Log, nothing there. Open to suggestions.

So after changing to COM ports for the first time the active WSJT-X instance went red while transmitting. Had to click retry to get green indication on dial frequency. Two other instances had a temporary disconnect as the slice flag moved to the center of the panadapter display. 

Patrick

No, just  wsjt-x....  Yes, I can creat ports? Only need one.   Again, I have no problems with CAT operations, it is only if I leave the station running and not do anything for a period of time 1 hour or more.  Then CAT disconnects mostly PTT functions, but occasionally frequency display in Log4OM.  Which uses OmniRig and assigned com port, but that still uses CAT functions.  This is not computer related, but could be software related.   CAT, TCP, UDP, COMports all are involved.  Not being a software person, but well versed in data com.  I can only make evaluations based on what I know and observe.  I do know that if these CAT related problems are taken seriously the problems  will be solved eventually.  I hope......

Please check to see that each 3rd party software connection utilizes a unique TCP or Serial port.  You cannot share ports amongst apps.  All 3rd party software assumes it has exclusive access to a port. 

CAT port connections can also be impacted when your PC goes into standby or the screen-saver is activated.  I've experienced CAT PTT disconnects with WSJT-X when my screen saver activates even though I have the sleep (power-saver) function on my PC turned off. Each 3rd-party app can respond differently to the messages Windows sends to running applications when sleep/screen saver functions timers expire and turn on.

If you routinely expect to keep CAT/TCP ports active through periods of inactivity, turn off your screen saver and sleep functions.

Further investigation shows I opened a ticket with the help desk in November detailing all instances disconnected from CAT. This also coincides with the release of 3.1.8.. Will reopen that case as an FYI, looks like there might be a bug in CAT 3.1.8 

Patrick

Thanks, Dan, I do not sleep the computer, but I do have screen saver active.  I will check with it off.  Thanks for the suggestion!

Patrick

Also Dan, all UDP/TCP assignments are correct.... no operational issues.  Just pesky CAT disconnects...

Patrick

Dan, just a suggestion, how about some sort of keep alive signals? A general broadcast and response command, if that exists in the CAT function list?

Another thing I have found in Windows 10 was screen and mouse freezing for a couple of seconds every minute. I traced this down to the desktop background image being set to Slide Show instead of a static picture. Every minute Windows would change the image and color scheme to match the image. That correlated with the freezes.

I concur absolutely with Bob - network issues present just like this. In my case, I'd come back after an hour or two, sometimes overnight, to find that both CAT and DAX were disconnected. I'd disconnect and reconnect the radio, and all would be well for anywhere from hours to a day or so, then it would drop again - disconnected DAX and CAT. Tore my hair out, but eventually decided it must be a network problem.

Changed the switch I was going through to get to the radio from the computer, and I have had zero disconnects in days. In my case, this was with xDax plus Loopback and xCat on a Mac with JS8Call. Happy camper after a physical network change.

Your example, is exactly the way I set up wsjt-x.  Has been since the first time wsjt-x properly got the Flex 6000 radio selection working.... Now I am going to through another log on the fire.  DAX is also going to sleep.... radio keys but no transmit audio and  this requires me to quit SmartSDR completely and restart it.  Basically these problems are irritations, and under normal or continuous operation all works fine.  

I have not tested the monitor screen saver yet, will try that soon to see if that causes the problems. 

Patrick

Hi David, don’t have that configuration issue, I just have normal screen saver operations.  But as I said I will be testing with the screen saver turned off.  That will take a few days.  That was an interesting problem you described.  It’s one of those Widows traps that can crop up, and make you scratch your head and say, “how the he#$ did that happen”!

Patrick

So far so good, with screen saver off, did not have any problems overnight.   Will continue test....

Patrick

So, the question is, what in the screen saver or DAX/CAT when used together, that is causing the problems?

Patrick

I had previously visited the related power options in Ethernet, screensaver, and computer sleep.  Also, did a full stop on all security settings, which I will reinstate as I get more confidence with the screen saver issue.
