AS Dave suggested I started with COMMANDER. I use WIN4Yaesu to control my FTdx5000.
I connected Commander to one of the WIN4 com0com ports. Since I know nothing abt DXKEEPER 
I connected LOGic 9 to another WIN4 com0com port. When I change the freq. on any of the 3
(WIN4, LOGic 9, or Commander) the others change also. Plus COMMANDER tells %of RF pwr.
I still have a lot of study of the COMMANDER to do.
I am a happy camper.
One Quick question.
Will DXLabs support using the Flex Tuning  knob?
