problems with ft950 decoding wspr

Really I am very impressed by the wspr. I am active of cw to 100 % and the truth is that I hallucinate when I see that month they are listening in vk with only 100mw with my dipole.
And everything with my old man FT817ND and one interface USB rig expert standard.
What I cannot fit still it is my newly FT950 not if it is for the DSP that is not a good ally for the use in wspr.
