Transition Layer & jungmeister,
Completely agree. Up in my neck of the woods we use 123.0 (within range of 133.0), 133.0, 133.2, 133.8 and 134.4 (within range of another station 124.4). We are very careful to listen for frequency readbacks (hence also why I use TREE, especially with a number of foreign pilots in the area), and still some go to the wrong frequency!!
