If I set the sampling rate to minimum (225001Hz) with rtlsdr_set_sample_rate() and also set an frequency correction of say 25ppm with rtlsdr_set_freq_correction() then there are glitches in the sampling.
I think this is because of the applied frequency correction. It leads to an sampling rate below the allowed minimum or something.
225001Hz - no frequency correction
225001Hz - 25ppm
Here you can see the periodic higher and lower intesity which is not correct. This is what I mean by "glitching".
