Does this manifest itself with tones popping up in the full spectrum when sample rate is changed? I was trying to research this issue.

@theproxy Sample rate changes trigger re-calibrations which generates tones. This issue is unrelated.

Ok thank you. Is there a way to supress the tones from the output on sample rate change?

You can put cals into manual mode: https://wiki.analog.com/resources/tools-software/linux-drivers/iio-transceiver/ad9361#calibration_mode_controls
However there is no expectation on QEC performance when you do this.
