Hi ccsh and ashley.b,
Thanks for sharing your experiences
In my case, it was used the “kalibrate” application (adapted for UHD) for similar purposes (clocks from local GSM/DCS BS) without successful results for LimeSDR (SoapySDR-UHD and OpenUSRP drivers). You can read about my tests in: LTE signal identification
Probably it is a different issue, although is also using the calibration data stored in “.limesuite/LMS7002M_cache_values.db”, anyway, I’d like also to know about a reliable and repeatable “Calibration Procedure” valid for Tx and Rx in both channels.
Cheers
BelmY
