Momentary Tx when changing frequencies

I don’t know if this is a problem with SoapySdr or the SDR program i’m using … or Lime’s drivers for Linux …

I use LimeSDR-usb on Ubuntu 18.04 with SdrAngel and when ever i change frequencies with the Tx playing and mute on (the icon with the -120DB) showing … i get a momentary Tx of signal … i have not
used FM and no other mode …

Just wondering if any other FM SSB AM sdr programs show the same issue …

This sounds like the same issue:

It might be just Tx calibration being executed after each frequency change.
