Hi, I would like to use my E4k dongle for wider spectrum analysis. Currently the tuner is very specific to a frequency. Is there a way to widen its bandpass filter? I have noticed some filters in src/tuner_e4k.c: Mixer filter, IF RC filter and IF channel filter. Are they of any use? Is there a librtlsdr API? TIA, Nikos
