I don't believe you need to build a level converter -- you just need to wire
up a cable to connect your PC's RS232 port to your FT-857. The pin-outs are
given in your FT-857 manual.

Hello !
I'm looking for any circuit to control my yaesu FT-857
I don't want to buy the CAT system box, I want to build
the interface.
The main purpose is to control the radio with the logging
software I use (DX4win and CT).
If you have the circuit or know about any web page where
it might be please send me an e-mail.
I've search a litle on the web but mostly I find are
advertisements about radios with CAT system, not the interface
wiring !

Thanks !
