bluskis:
Mode S has been debated on the ATC forum several times. This may be why you are having a slow response.
Last thread I read seemed to conclude that there was little benefit for ATC in having GA outside controlled airspace squawking mode S. If all flying machines so squawked, the radar screens would be so overloaded that they would have to filter-out the squawks of no interest. I believe the TMA controllers (and some airways) filter out 7000 squawks now.
Why not do a search and you will see what I mean?
