There's no problem with it for a digital network node.  The problem  
is if there are too many stations using it at once.  As you get one  
that is higher, more and more stations can use it.

What's the current channel loading, for instance?

In Wyoming, we use several very high digis (3000' HAAT isn't unusual  
but more the rule).  No problem - we have a lightly loaded network.   
Why not support wide-area communication if loading is low?
