TAPR.2
        The KAM seemed to perform as well as the MFJ. Encouraged, I 

  built the second State Kit. This one was going into my AEA PK-232.

  Being gun-shy by now, I was careful to follow the PK-232 installation

  instructions. Lo and behold, the instructions said to wire the DCD input

  and output to JP5 of the PK-232. Unfortunately, JP5 is the Transmit

  Data Lead, not the DCD lead. Moving the connections to JP6, the DCD

  lead, produced satisfactory results. The moral of this story is to 

  take all instructions with a grain of salt. 

        All four units are installed and do work "as advertized". Do

  take care when installing them to watch for these errors in the 

  instructions. If another type TNC is involved, be aware that there

  may be difficulties in the instructions for installing the mod in it.

        Give these units an "A" for performance and a "C-" for 

  documentation. Good luck.
