I should have come back to the group sooner. I didn't get an e-mail that my original post was answered. Anyway...bingo! Yes, when I reduce power, (down to 45 watts) even on the upper bands, the radio is performing nominally with WSJT-x with my IC 7100.. But... and this is one I can't understand...I was only using 10 watts with the IC 705 and it was still failing.
