Hello Mike, Uwe and the wsjtx development team. I thank you for the supporting me.
I was very sorry for asking such a strange question that had trouble JT65B of WSJT-X. I find the cause of in trouble of use two JT65B. In my case, the cause of my trouble was the USB3 port on my PC. I reported you about my situation and after that I will need using two JT65B on the EME then I installed two WSJT9 for two JT65B. And then my strange PC told me when I started the second WSJT9 that the PC said "Not Enough USB Controller Resources error message" You know that the cause of this error of the USB3. In my case, I do not need to use the USB3 port for my PC so I attached two USB sound cards on the USB2 port of my PC. But my PC was strange PC, I think probably they were recognized by the USB3 port with my PC. Therefore in my PC, I think the two USB sound cards were strange motion with use two JT65B. But I think my PC did not tell me that error when used two JT65B of WSJT-X. After that in my case, I changed the BIOS setting on my strange PC to not use USB3. Any way I am able to use two JT65B of WSJT-X to working well on my PC. And I am installing the JTDX APP but I have no problem until now. I thank you and your team so much again. Taka, JP3EXR
