I think it's because small/low aerials lose more signal to surrounding 
ground clutter than do big/high aerials. I don't believe that trees, 
buildings and hills necessarily appear as part of the loss resistance 
you mention.

Nobody disagrees with you. What Mal said was "there is no need to use 
QRS to be heard around EU". It seems a shame to use a slow mode if a 
given path supports a faster one.
