TOPIC: Failed to read the device calibrations!

Failed to read the device calibrations! 05 Aug 2023 13:49 #16

I pulled the power connector from the SDR2 Pro for a hard power reset, plugged it back in, then ran ExpertSDR2 (not 3) and upon opening it updated the firmware and now ExpertSDR2 is running normally. I'm going to wait a while before I try to install ExpertSDR3 again.

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.

In the newly released User Manual, Ver 1.0.0 (Prelim), look at Para 18.1; Page 94.
There is a description of things to do in case you get the "Failed to read Devie Calibrations".
