Hi David, Marcus,
I just had a quick try with one command. The result has come out - I find the
expected .cal file :)
Thanks a lot!.

Thanks for picking up on that! Yeah, there's ZERO reason to run as root for
this stuff.

Thanks for your quick response Marcus.
My Linux is server version of Ubuntu 22.04.
The calibration commands I used are:
sudo uhd_cal_tx_dc_offset --verbose --args="addr=192.168.13.2" --freq_start
0.4e9 --freq_stop 6.0e9 --precision 0.00001 --freq_step 5e6 --subdev="A:0"
sudo uhd_cal_tx_dc_offset --verbose --args="addr=192.168.13.2" --freq_start
0.4e9 --freq_stop 6.0e9 --precision 0.00001 --freq_step 5e6 --subdev="B:0"
sudo uhd_cal_tx_iq_balance --verbose --args="addr=192.168.13.2" --freq_start
0.4e9 --freq_stop 6.0e9 --precision 0.00001 --freq_step 5e6 --subdev="A:0"
sudo uhd_cal_tx_iq_balance --verbose --args="addr=192.168.13.2" --freq_start
0.4e9 --freq_stop 6.0e9 --precision 0.00001 --freq_step 5e6 --subdev="B:0"
sudo uhd_cal_rx_iq_balance --verbose --args="addr=192.168.13.2" --freq_start
0.4e9 --freq_stop 6.0e9 --precision 0.00001 --freq_step 5e6 --subdev="A:0"
sudo uhd_cal_rx_iq_balance --verbose --args="addr=192.168.13.2" --freq_start
0.4e9 --freq_stop 6.0e9 --precision 0.00001 --freq_step 5e6 --subdev="B:0"
After running these commands, it showed that calibration was successful:
The calibration was successful!!! :-)
What other place can the .cal files be saved in?
Thanks again.

Hi,
I installed UHD 4.4 for X310 and calibrated USRPs, but I can't find the
expected .cal file under ${HOME}/.local/share/uhd/cal/. Actually, there is no
${HOME}/.local/share/uhd/ directory.
What can be wrong?
Thanks for any help,
Hongwei
It could be that your desktop environment stores local config and data files
in another place.
What commands did you use to create the cal files?
