I ran my K3 with internal autotuner on the DX Engineering 43' fast-taper vertical with their 4:1 UNUN with excellent results on 40 meters and up. I tried a couple of local qso's on 75 and it worked ok, but I was only running 100watts on a KW band. I tried loading on 160 meters and think it did load, but the QRN was so bad I never tried to make any contacts.
This was all at my Arizona QTH where the vertical was my only option. I replaced my Butternut vertical with the 43' vertical and definitely thought it was the better antenna. Ground field was poultry netting spread out in an X pattern about 30' on each side. If I could hear it, I generally could work it. Again all done with 100Watts. You refer to the Elecraft tuner for the KPA-500, I don't know there is one, yet.
