[Yaesu] FT-757GX CAT question

Wed Jan 10 08:27:19 EST 2007

I just purchased an FT-757GX with hopes of controlling the rig with my 
computer. I find that most hardware/software will work only with the 
FT-757GXII.
In my search and in an effort to avoid purchasing an FIF-232C interface, 
which can still be pretty expensive, I have found only one reference to 
controlling the '757GX. This was in a QST article on building a MAX-232 
interface from February, 1993, where it says that the '757GX uses only 
the RxD commands from the PC and sends no confirming data back (except 
independent band-select data). The Yaesu documentation is unhelpful in 
making this determination but it appears that the RxD line form the 
interface is just hooked to the "REM" pin on the little 3-pin header at 
the back of the rig. Can anyone verify if the information I have 
gathered is correct?
