LMS_Calibrate() always failed at GPS L1 frequency

LimeSuite / src / examples / singleRX.cpp works nicely at the default 800MHz, but it always failed with “RX calibrateion: MCU error 4 (SXT tune failed)” at 1575.42MHz of GPS L1 frequency.
Is there any specific frequency or bandwidth which won’t work with LMC_Calibrate() function?
