USB-57A which is listed for the FT-4X. Windows 7.  I believe I'm using the 
latest daily download.

Subject: Re: [chirp_users] Yaesu FT-4X Download Problem

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.

ANY help appreciated.
