Having a bit of a challenge getting FLDigi to work with my rig CAT control. Downloaded and installed the latest version for Windows (4.1.03). Radio is a Kenwood TS-140S that works with both N3FJP logging software, and WSJT-X software for CAT control. The radio has the Piexx interface board installed, and connects back to the PC on COM1. I downloaded and installed the XML file for the TS-140S and the software recognizes it. I mirrored all the settings as best I can tell from the other software back to FLDigi. Yet there doesn't seem to be any communication between the radio and software... when I change frequency on the radio, the software display doesn't change. The sound card is a SignaLink USB and I seem to be getting audio from that into the software. All I really want to do with this is RTTY, PSK-31, and receive WEFAX.
