To the list - I have yet to solve my problem with my KAT2.  So far I have
replaced T1 which yielded the correct 3.4v on TX on the input to U4 and
0.74v on RX.  Unfortunately U4 was not buffering that through to R6 so I
replaced U4.  I now see the 3.4v on R6 in TX BUT 2.4v in RX.  I have yet to
find where this 2.4v is coming from.  NOTE: this is present even when R6 is
not connected to the board.  Obviously when R6 is in line, it blanks the
receiver due to the high voltage on it.

I'm already in deep correspondence with Don and Gary but if you have any
ideas please do not hesitate to drop one to me as well...

Thanks and wish us luck!
