. I am able to connect to my computer and manage CAT functions and various digital software programs without problems. But I was unable to get sufficient audio stream via 9100 USB to my computer. After several online conversations I bought a rigblaster advantage to handle such things and am still having problems with setup. I now get good audio from the radio to the computer and software, and PTT is handled just fine but I have no audio RF out from the radio either from fldigi or wsjt. I have no idea what's wrong. I think it may have to do with driver conflict as I initially tried a Signalink so it installed drivers and of course the rigblaster did the same, installing new sound drivers. It's interesting that if I choose the USB codec in the software setup for sound in and out, which I believe is actually what was installed by the signalink, the software radio connection works but if I use the sound in and out labeled rigblaster advantage it doesn't. I should add that none of the level controls on the RBA work either even when I choose the USB audio codec as sound sources. Clearly I'm doing something wrong but I can't sort it out. I never had so much trouble getting digital mode software to work on a radio. Frustrated, Rick, W2JAZ
