Scanning through frequencies in config do not work for me #13

Hello,

when i try to use your scanning tool it just does not work for me as it should do.

I have two bands in my config but the second one is getting ignored, but why?

config: { "frequencies_ranges": [ { "start": 144000000, "stop": 146000000, "modulation": "fm" }, { "start": 430000000, "stop": 440000000, "modulation": "fm" } ], "ignored_frequencies_ranges": [ { "start": 28799000, "stop": 28801000 }, { "start": 115199000, "stop": 115201000 }, { "start": 438470000, "stop": 438490000 }, { "start": 439000000, "stop": 439010000 } ], "device": { "ppm_error": 0, "tuner_gain": 0 }, "scanning": { "noise_level": -7.9, "bandwidth": 2000000, "samples": 1024000, "fft": 16384, "peak_width": 10 }, "recording": { "min_recording_time": 4, "max_recording_time": 600, "max_silence_time": 2, "samples_rate": 48000, "samples_count_to_adjust_frequency": 100, "channel_width": 12500 } }

command: ./sources/main.py config.json -pbf 1 -vvv

It scans frequencies 430-440 too in background, but it prints only the strongest frequency per single loop tick (144-146 in your case). Please try to send some transmission on 430-440 and check.
