Hi, ExpertSDR2 works beautifully.
ExpertSDR3 no way, thought I would try the new "bugfree" Expert SDR3.
I have started the SunSDR2DX from the Devices section now have the main layout for the radio, I press the "power" button top left of screen, the radio starts then after 5 seconds get the "Lost connection with SunSDR2DX!" message.
Any suggestions please!

Firmware ?

Chack that the connection is not denied by your firewall.

I have enabled ExpertSDR3 in the Windows Firewall. I have loaded the Firmware. No joy.

In addition you also have to enable the internal network in the radio.

But something still missing... What is would be... Hah! Have you read the manual and FAQs?

I figured that because there is initially on switch on a connection to the SunSDR2 which is then lost (the same problem I had with ExpertSDR2 a few years back) that it had to be firewall related. I therefore disabled the windows firewall and hay presto" all works!
Just need to figure out how to enable the program ExpertSDR3 to run with firewall enabled.

You can enable sdr3 in firewall program.
Happy new year.
