Thanks, Don. That is what I was figuring too, but I wanted another pair of
eyes on it! The TIK2 uses both the 8R and 8T lines - typically 8R is used for
transverter PTT, while 8T is (optionally) used to switch the bias to the K2 PA
to ensure it stays off when using the transverter. I think it would probably
be ok to leave it unconnected, but I'm just reviewing my options. 73,Steve

Steve,
As far as I can determine, no harm would come from making that connection.
IMHO, it would be better to invert the 8R signal, but then I did not
have any 'say' in the DEMI design.
