Hi Nikolay,
i don't see any option to do IQ calibration in rtl_fm !?
As i wrote to Murat, the DC is NOT the LO !
The spectrum already looks clean. I don't have a problem with the symmetry.
The "dc" option does work too late: after demodulation.
kind regards,
Hayati

You need IQ calibration.
When calibrated, spectrum should look much cleaner, signals should
appear only on 1 place of the waterfall/spectrum display, and the LO
carrier (the so-called DC) will be much better suppressed, although not
completely removed (that's why the -dc option exists for the baseband
processing).
Regards,
Nikolay
