Andre,
Sorry for the delay. I uploaded 3 sets of logs to the following Gist.
Warning level logs, Info level logs, and the console output of `sudo
srsenb` while capturing the Info level logs.
https://gist.github.com/JamesHagerman/784a009ae8ab4886c32d1dd0a726352f
The only line in there that is a bit worrisome is:
[ERROR] Tx Calibration: MCU error 4 (SXT tune failed)
But I've tried just about everything I can to get that to go away and
nothing works. If you think that is the root cause, I'll reach out to the
LimeSDR community and try to sort it out.
Thanks again for the help!
James
