Laurence,

On my old LF grabber PC it is easily possible to run 6 SL instances 
without problems. But, if Opera bahaves about like ROS regarding CPU 
load (i did some ROS VLF tests for a few days in 2010, until i found 
that it cannot decode signals that were more than O copy in DFCW-3),  it 
would be a problem for that PC or at least at its limit.
A pity about loosing the ID of that traces in the ARGO screen, seemed to 
have been OOO copy...
How many Opera decodes in AK so far, on 137?

73, Stefan
