FT8 JS8Call & Winlink over USB on (tr)uSDX 

Thank you for the comment & I’m glad it helped. Best of luck with your (tr)uSDX & 73!

Thanks for the comment. Audio coming into the JS8Call would seem to mean that the Settings>Audio tab>Input is set correctly to "Cable Output (VB-Audio Virtual Cable)", but maybe the Output is not set correctly to "Cable Input (VB-Audio Virtual Cable)". Other things to quickly check would be: Firmware version, menu option 9.7 F/W, must be 2.00u. Audio volume, menu option 1.1, was +4 in my video but I've increased it up to 7, 8, and even up to 10 in other tests with positive results, so you may want to vary that. Also, I'd concentrate on getting WSJT-X>FT8 to work since we always seem to have FT8 signals and WSJT-X is pretty solid software. The idea being that if the settings are correct for FT8, and the problem persists, then it would seem that the problem is hardware related. Heads up that Manuel DL2MAN mentioned in one of his videos that he tried about 4 different USB cables before finding one, a short length one, that worked. Other than that, I'd methodically check the different settings for FT8 and get that to work. Then proceed to JS8Call. Hope that helps. 73!

Thank you for the comment. 73!

I've tested but I've a problem with audio in RX and TX... 😞@@quantumradio

Hi I've Test now and it's working... i don't understand that I've need to start a truSDX Driverv and don't closed Driver, Tnx best 73 de IW6CAE@@quantumradio

Thank you for the comment. In my case, I didn’t use the digirig add-on module so I’m not sure what the issue could be; however, I’d suggest joining the (tr)uSDX forum online & posting your configuration, settings, and error message. A lot of experienced & sharp folks post there, so good troubleshooting goes on in the forum threads. That would be my suggestion to find the root cause. Hope it helps & 73!

Thank you for the comment. 73!

I can't get it to work.

It sounds like you're talking about the needle on the signal meter at the bottom left of the VARA window showing red and not coming down to yellow or green. I'd suggest lowering the volume in the (tr)uSDX to 4 or 5. 73.

Thanks for the comment. Yes, I'm running 2.00x now and WSJT-X worked fine with it. Best of luck & 73!

Thank you for the comment. It may be that Winlink has a COM port other than COM8 selected. I'd check the Winlink>Open Session (Vara HF Winlink)>Settings>Radio Setup & ensure tht Radio Control Port>Serial Port To Use = COM8. 73!

@@quantumradio thanks! That’s what I try to do, is to use com port 8. Every attempt results in com port in use. When I select a different com port it allows it, but of course there’s no connection between the two. Then go back to com port 8 and get the same in use message

@@tjs2909 Yes, the TRUSDX Driver uses COM8 & CABLE audio devices in WSJT-X or any other HAM radio program. So I don't believe that it will work on another port. When I run Winlink I first run FT8 with the configurations shown in the video, then exit FT8 (do not exit/restart the TRUSDX Driver or unplug cables), next I launch Winlink with the configurations shown in the video, and COM8 is then successfully used by Winlink. If you're doing this sequence, then it sounds like COM8 is not being "released" by Windows prior to running Winlink. That's interesting. For further troubleshooting, I’d suggest joining the (tr)uSDX forum online & posting your configuration, settings, and error message. This way the issue is shown to the (tr)uSDX user community. They're sharp folks in that forum & they may have the solution. Hope it helps & 73!

NM...LDO..I had the js8 slider all the way lowered.

May be the length of the USB cable. DL2MAN did say that he went through 4 USB cables before finding one that worked for him. I believe that he ended up using a short USB cable for best results.

​@@quantumradioWill try. Also turned off semi qsk and will try later.

@@quantumradio it works now

Thanks for the comment. My setup didn't require the Digirig, just a sinigle USB cable from (tr)uSDX to the Windows laptop. I have heard of folks having good luck with the Digirig. It may be that the Digirig connection is more reliable than the single USB cable I've used; however, I don't have first hand experience of the Digirig connection to compare. Best of luck and 73!

Thanks for the comment. The Winlink & VARA software & service is free though I paid for the "VARA license" & can in theory send/receive at faster transmission rates than w/the free version. As far as Winlink is concerned, I believe that you do have to have a callsign & signup to use Winlink, though I could be wrong. I have a Winlink account but not sure if it's required. Good news is that you can send/receive your emails to/from any email address, e.g. wxyz@gmail.com, abcd@outlook.com, etc. Hope that helps, 73!

@@quantumradio I got it working. Pretty cool stuff! Thanks

You're referring to JS8Call from what I can tell. I'd say get the latest version of that SW and see if that fixes it. Best of luck & 73.

@@quantumradio yes I was, I installed it this morning. Pretty sure it's the latest

@@justawfulgamer7738 JS8Call version 2.2.0. Try clicking on Menu>Mode>Enable HB & Enable ACK. That should do it.
