dcs is like pl but digital. I run a dcs tone on my repeater on 900 MHz. It's 
supposed to be less prone to being triggered by the right tone of 
interference or whatever brings up a toned repeater when no one's there but 
I don't see much difference. that or someone has a lot of fun listening to 
my repeater ID even when it's dead for hours.
