FT-840 and WSJT-X how to connect?

[hdjmings1]

Hello all

I have an ft-840 and i have cat control that i use to control my logging software log4om

I downloaded WSJT-X and have put the setting on the radio i use and the correct com port

What i want to know it how does this all work im new to ft8

I have the radio on and cat lead in pc and set to the correct com port (com port 2 in my case)

I sent a lead from the ext speaker port on the back of the radio to the mic input of my pc

The output was put to my speakers (pc) but when i test it and the radio keys up i get a god awful noise (i know im new but its not ft8 sound)

What have i done wrong?

I would try connecting AF out to Line in for the radio to PC path, see if you can get a decode.
The TX path I'm not sure, PC line out to mic in, but that maybe too much - you are probably best looking for a FT840 USB interface, such as the tigertronics.
On top of which, I'm not sure the FT840 Oscillator is stable enough for digital
