Set lower tuning limit to 0MHz for RTL-SDR Blog V4 #70

Closed rtlsdrblog closed 1 year ago

rtlsdrblog commented 1 year ago

The RTL-SDR Blog V4 can tune down to 0 MHz (in reality ~300 kHz) because of the built in upconverter. This change detects the Blog V4 via its R828D tuner, and the manufact and product strings, and sets the lower limit to 0 MHz.
