When I started using the Yaesu System Fusion stuff, I really wanted to try Wires-X. I upgraded my FTM-100DR to an FTM-400XDR as my mobile and put the FTM-100 on base station duty. I really like using APRS when I’m out and about, so the dual receivers of the 400 was better for that. One of our local repeaters, hosted by Greg K4HBM, has a Wires-X module on it, allowing me to connect it to any number of rooms or nodes.
