RTL-SDR OpenwebRX direct sample mode configuration 

Below show an example for config_webrx.py  file

just add   "direct_sampling":2,

======
sdrs = {

        "type": "rtl_sdr",
        "ppm": 0,
        # you can change this if you use an upconverter. formula is:
        # center_freq + lfo_offset = actual frequency on the sdr
        # "lfo_offset": 0,
