for the reference of you all who are interested in this mode. 
the mystery is solved - the culprit found:
We found out that a frequency offset is introduced, when I choose a
different filter for receive than the default 2.7 or 2.8 filter. There is a
bug in the firmware when using the -s command and Lyle and Wayne are working
on it. For me pactor and other ARQ data modes work very well when I do the
following:
disable all filters for data modes in Filter configuration of the Utility
program except the 2.7 or 2.8 filter
or choose the 2.7 resp. 2.8 kHz filter for receive. 
choose -s for data modes
use PTT RLS of 20 in configuration menu.
mni thanks to Dave, Brendan, Lyle and Wayne for the help in finding the
cause for the problem and solving it.
