The following video on youtube was a lifesaver, so to speak. I purchased a new, more powerful CPU as the old one just couldn't handle PowerSDR 2.8.100+. It's nice going from a CPU usage of 91 to 100% to a more managable 30 - 45%.
My problem was trying to figure out how to get DDUtil v3 and VSP Manager coordinated with my FT8 program. The solution was simply to set up pairs of virtual cables and assign all the top virtual cables to use DDUtil ports and the mated v.cable to be set to PowerSDR or WSJT-X or fldigi or N1MM and the like.
