Yves.....
    Here is the pin out for the Icom 02AT HH to the PCB-88.

        DB-9 Pin 4 (Mic) -  Tip of 2.5 plug (mic jack on 02AT) - put a =
.1uF cap in series between                                               =
  the TNC and radio. ( that's a POINT 1 uF cap)
        DB-9 Pin 5 ( Speaker Audio) - Tip of 3.5 plug (Spkr. jack 02AT)
        DB-9 Pin 7 (Grd Shield) - Sleeve of 2.5 mic plug (mic jack 02AT)
        DB-9 Pin 8 (Grd.) - Sleeve of 3.5 plug (Spkr. jack 02AT)
        DB-9 Pin 9 (PTT) - Tip of 2.5 plug (mic 02AT) - put a 22K ohm =
resistor in series between
                                           the TNC and radio.

    Let me know when you're ready to proceed ! I haven't tried APRS or =
TelNet with mine, but I think with the appropriate software, it should =
work. But let's see if we can get the computer, TNC, and radio talking =
to each other first :-)

Cheers......
