No, not yet.
I got this message when updating to expertSDR3 latest version.
Till now I get no answers,..

I thought it could be a problem with my firmware 68.7 of the SUNSDR DX.
So I I am trying to update this.
Also no luck.

I found that if I just turn the SDR2 Dx power on and only bring up the Start / Stop Gui for SDR3 V 12.1 SW and clk on the Firmware Manager, wheel in the lower right corner, it will ask for the FW update if needed.
Click on that and it should update.

:) Hallo again I have succed with that I can now start my tranceiver again. But the "fail to etc message" are still there when the tranciever window opens. But as soon I hit startbutton everything seems to work as nomal and failwindow dissapears. I have to look more tomorow. What I did was to go in to the ip number setup as I did when tranceveir was new. I put in the number and then hit ok started the tranceiver and it started. I have no antenna do to a storm but will put it up tomorrow again and see if everything is allright Had also sent a mail to the support. So we see what they say. Maybe something happen when I changed from wifi to cable connection with the IP numbers . Now it is time to go to bed

Now I am back to my first problem with the tranceiver disconnct Today it worked 5 hours then disconnct and next stop was 30 minits after that. I am using a netcable today and no WiFi. Before FW 78.8 I did not had that problem it worked also with wifi all time. So testing is going on :unknown:

No disconnect in 24 hours :D Using WiFi and Log 4om last 8 hours. What I did? In windows controlpanel I take away V3 0.12.1 Then a new installation of V3 0.12.1 for the third time
After that I lower my powersupply from 14,0 volt to 12.8 volt . First running about 12 hours with no connection to wifi or netcable just the tranceiver no Log4om. This night or early morning 03.00 I start the wifi connection no problem and a couple of hours later I start Log4om I have also rise my voltage to 13,5 and I am happy with that. All is still working Also Stop and start all to see if it starts ok and it did.So far no problem . Maybe it is a limiter on the voltage? I dont know, but earlier I think the limit was 14.5 volt. Anyway I am really happy after several days struggle.

I just discovered (today) that some third party software can cause this issue with both the sdr2 and sdr3 version of software. Don't know the technical particulars yet but do know when I uninstalled the latest software program I installed to my PC right before this started to happen to me, the problems went away completely when the software was disabled or uninstalled, either way.
This was completely reproducible 8 times in a row. I hate to say which software it was for fear of reprisals. I'll just say that it is one of the most popular remote desktop software out there. When uninstalled or disabled, the radio and expertsdr3 and expertsdr2 both worked just fine without any other intervention.
So you guys may want to investigate conflicts with ip addressing and ports and software code as a possibility of this problem. It was not a cable, router,or any other hardware issue in my case.
I hope this helps somebody.
