Here is the schematic that I used to interface my GLB PK-1 to an
Icom IC-2AT HT, but it should work with any TNC and the Icom 02AT
or 2A just as well.


                      Audio out         PTT        Ground
                      from TNC
                         |               |           |
                         /      (.47 uf) |           |
                         \               =           |
                  (25K)  /               |           |
                         |               |           |
