I will jump in on this topic.. with the TS-440. Using the TS440, one can use the RCA Phono jacks on the back of the TS440 labelled AFSK In and AFSK out. Then use vox to key the rig via software like DM780 , Fldigi. or Multipsk. Using this method with plain audio cables results in NO isolation between rig and computer and increases the chances of ground loops causing distorted or noisy transmitted tones. If you keep the transmitted power to around 25 watts or less , you can usually get a clean signal. You can use home made circuits to isolate the rig-PC or buy some commercial products usually made for car stereo systems that eliminate ground loops.
