PK-96 and TS-2000X

After some debugging and measurements, I finally got my PK-96 working with my Kenwood TS-2000X where I use the TS-2000X ACC2 connector. The problem was that when one uses pin 13 PTT the TX audio from the PK-96 is muted. This pin is normally used for a foot switch and not for an external modem. So after I switched pin 13 to pin 9 on the ACC2 connector everything was working. ISS packet here I come.
