Using VarAC with VARA FM Mode on the Yaesu FT-991A via a Single USB Cable. I'm currently using VarAC with VARA FM mode on my Yaesu FT-991A, connecting to the radio with just one USB cable. If you know of a more efficient setup or have any suggestions, please share your insights. Additionally, if you spot any errors or conflicts in this setup, I'd appreciate your input. Testing with ICOM ID-31Plus handheld, connected to a Digirig Mobile v1.9. Note that the handheld is limited to "Narrow" VARA FM settings. Need to also test using "FM-D" on the FT-991A. So far, I've successfully managed Chats, CQ CALLS, and Beaconing with both setups. However, I haven't received any broadcasts yet, and I'm unsure if it's an RX or TX problem. I also haven't attempted to send files yet but plan to do so soon. Kevin JJ1PJI
