IF they are suppressing due to excess clutter, and IF they then turn
suppression off they will see VFR traffic. Normally, they do not suppress.

This began as a suggestion only to call ATC to find out if, and when, they
suppress in your are before spending the money. There are other things, such
as TCAS, which may well be reason enough to purchase a transponder.

So, are you saying that while an IFR aircraft is outside of Class B
airspace, and under ATC control, then ATC will turn off suppression so
they can see the VFR traffic?

If I've got that right, then isn't that what we want? ATC will keep
IFR aircraft away from VFR aircraft (that's me in my glider with my
transponder) while I'm outside of Class B airspace (the usual
situation).

I've never expected ATC to keep VFR aircraft away from me, though this
can happen if the VFR traffic is using Flight Following.
