Do you use TXLPF and which if yes?
And also, please let us know other registers dump of TX part, especially
TXVGA's.
Btw, unfortunatelly, I do not know how to switch LPF otherwise than by
direct registers access.
Now I work with power consumption and forced to write to registers to see
can LPF to suppress spurs (which occur without LDO regulators) or not.
I set LPF through the UHD interface. This was necessary because the
default setting was too narrow. Unfortunately, I did not capture at
any register values.

I don't see how the LPF can suppress these spurs because they occur
inside the multicarrier passband.
