I ask you to give the most detailed explanations of the appearance of these artifacts.
honestly I don't know ; these transponders are already known as NS3/4 thank's Feedsat :
the only this which unknow is their Symbol Rate???
TBS5927 doesn't support NS3/4 ; but I think it worthy to try feed-reports on NS3/4 transponders
I/Q N=5500*10 is used in feed-report this time
sorry if I can't explain better
It will be very good if IQmonitor can predict their SR like DVB-S2X
