rtl-sdr with bias T

Hi - there appears to be problem with rtl-sdr with bias T and the RTL2832U OEM Rafael Micro R820T tuner. I get PLL errors when I try to calibrate it using kal - or when I use rtl_test. Using device 0: Generic RTL2832U OEM Found Rafael Micro R820T tuner Exact sample rate is: 270833.002142 Hz [R82XX] PLL not locked! Setting gain: 33.8 dB And I get the same error PLL when I run rtl_test. If I back out of the latest git version to v0.5.3 it works correctly - I can calibrate the dongle using kal and run rtl_test without any PLL errors. This is a known problem? -- Cinaed
