I have been running the file for 15 minutes and it is still working even though the file source repeater is set to no.
The constellation at the exit of the FTT block engages with 64 points (+5), randomly engages and at 2 seconds they appear in a circular way (this also made it to the adv16.cfile file), re-lock them and the 2 seconds later or less appear in a circular way and so consecutively
The constellation to the output of demod reference signal only appears with a point in the center. The processor cores work at 50%
Best regards
