Several DX stations had neither a K or CR at the end of their messages.
When coupled with no trailing spaces, their calls were often cut off.

Since a CR generally contributes to the "jumping line" syndrome, the
best solution is to add *at least three* spaces after any printing
character at the end of a line to terminate a message macro.

If PTT is dropped early only the spaces get lost ... if the interface
and software properly handle PTT there is a clear space before any
garbage characters get added to the line.  The "penalty" for the three
extra spaces is less than 1/2 second so it should not impact even the
stations with the highest rate.

73,
