Yaesu FTdx101D
The FTdx101D is Yaesu’s 100W dual-receive SDR HF/6m flagship — same single-cable node wiring as the FTdx10/FT-710. Modern Yaesu SDR base. A single USB-B cable presents a dual Silicon Labs CP210x (Enhanced COM = CAT-1, Standard COM = CAT-2/PTT) plus a built-in USB audio codec — no external audio interface needed. Use the Yaesu 5-byte CAT protocol and set the CAT rate (typically 38400). PTT: key via CAT, or via RTS/DTR on the CAT-2 COM port.
