Both were connected to dummy loads, not antenna. I just repeated now with Multi- Control knob setting power to zero watts output on both the IC-7300 and the IC-705 radios with same results.
Question for you, was I to use the WSJT-X v2.7.0-rc1 as originally released or was there another version of it that we should have installed? The testing I did was with the originally released candidate WSJT-X but with your updated libhamlib-4.dll installed per your email.
