As stated in my initial email, the TNC is a PK232 at 4800 baud and
chokes were put on the ins and outs between the computer, radio and TNC
and then tested again for about six hours only to see the same problem
being sent to the server.

I changed the PASSALL from on to off and will see if that changes
anything in the next day or so...

I agree. I will contact a station nearby and follow up with that in a
couple of days. I will also investigate logging with my station and look
for anomalies.

Gomenasai, Mi dispiaci, (full bow), my apologies...did not push the
fault with KISS and/or Xastir. Just wanted to know if anyone else had
experienced anything like this. I did what I could with my bag of
knowledge, hence I threw it out to the group. I respect the sweat, time
and efforts it has taken with the group to put Xastir where it is now. I
hope my problem helps others that may experience the same thing.

Whatever I find with this, I will provide that for others to reference
for their notebooks. I don't like being the last one with the
information. Where's the fun in that?

I've got a lot to digest, give me a couple of days and I will reply with
my results.
