How about VOR ID's, RCO's, distant TWEBs and FSS stations?

For automated signals (not voice), distance is important. For voice,
I'm not sure that distance matters that much, since if they are far
enough away to be hard to hear, they are probably not an immediate
hazard, and controllers have facilities that provide adequate coverage
for the area that they control.

Do you fly?

As a pilot, only in simulation. As a passenger, only when absolutely
necessary.
