If the interfering signal is on a different azimuth, it is possible the "diversity" features already in beta PSDR would help if you have the 5000 with rx2 and a diversity antenna. w9oy has written up some of his experiences on his blog.

what additional techniques can we use to de-emphasize the adjacent SSB
signal in PowerSDR today?
