What cable are you using? (also, what OS and what CHIRP version?) The FT-4X and related radios use a half-duplex connection with TxD and RxD on the same wire. The Yaesu SCU-35 cable works, of course. but if you are using another cable you may need to modify it. I use a trivial connection via resistors to the serial port on a Raspberry Pi.
I need to get back into CHIRP programming, so I guess I'll fire up my FT-4X and play some more.
