Indeed. To Andrew it was interesting enough to prompt him to post
a usenet question about it!


I think most of you folks are thinking of this clearance delivery frequency
as being a separate position in the TRACON. That's extremely unlikely. Any
airport with enough traffic to justify such a position is an airport needing
a control tower. This frequency is almost certainly just an RTR located at
the field because the normal approach control frequency for that area does
not reach aircraft on the ground. It's probably labeled as a clearance
delivery frequency instead of an approach frequency because some other
facility not so far away also uses that frequency and airborne use of it
would interfere.
