For some reason known only to the FAA, both Dunkirk, NY (KDKK), and
Wellsville, NY (KELZ), two small, uncontrolled airports in southwestern NY
state that are about 60 nm apart, share the same ASOS frequency.


What makes you think it's known only to the FAA? Whatever the reason, I
would expect it to be known to the FCC. In fact, it may be better known to
the FCC than the FAA.

It's probably because there isn't another suitable frequency available.
