I have two rigs and computers going in my shack and I am up and running on my Icom IC-7300. I simply set it up much like WSJT-X in the settings and no problems. However, with my IC-7610, I am having problems. Although I used the same settings as WSJT-X, I have no power out. The CAT control seems to work fine, for the most part. I run split with WSJT-X and have COM 3 and COM 4. If I have it set to COM 3, it keys up the radio until I click, "Settings > My Information" and as soon as I do that, it unkeys. Weird, but if I change it to COM 4, it does not behave that way, although the PTT test works. So, bottom line, no power output on the IC-7610. Any help is greatly appreciated. I just bought the software and I am anxious to get started! Also, the soundcard test keys the radio but no power out, and it won't unkey the radi. 73
