The Script seems to stopped working OverflowError: Python integer -127 out of bounds for uint8

Hi,
i wanted to check the ppm of my rtlsdr but I got the following errror message:

{'f': None, 'm': 'dab', 's': 'rtlsdr', 'c': 'all', 'rs': 2048000, 'rg': 20, 'rd': 0, 'nsec': 10, 'graph': False, 'verbose': False}
let's find your SDR's oscillator precision
