Hi, in case anyone finds it interesting, let me tell you what happened to me today. After days without turning on the SunSDR2DX I find that once I start the program, when I press TUNE the program disconnects and gives me the famous message Failed to read the device calibrations.. When I keep trying to connect, when it didn't give me that error message error, when going to Tune or TX, it disconnected and gave me the error Lost connection with Sunsdr2DX.
I read in the forum and did a ping, seeing that it gave 0 sg. As a possible LAN failure was discussed in the forum, I restarted the SWITCH to which I have the SunSDR2DX connected and everything was solved.
I hope it is useful to you.
