Trouble with RTS
Hi there,
Still struggling with my FT767GX - PTT wont trigger TX from RTS on Com 1 or Com 3.
My PC is Win 10.
I am using a USB to RS232 adapter and a BC457 emitter follower to present the Ground signal reguired by PTT.
Is it possible that RTS via USB is not available on a PC with no RS232 card.
Many thanks,

Ok all up and running...

I purchased a USB to RS232 converter and set it up on Com 3.
Initially I had some confusion with the RS232 pinout and chose to use a BC5547 transistor to present earth to the PTT RCA input.
These two references were helpful.

I still cant test the PTT without getting 'access to Com3 denied' but I simply tested by sending the beacon repeatedly.
So all good now and most impressed by the potential of VarAC and the great work done by Irad.
