Short Final
After a VFR departure from a satellite airport, I called TYS approach. Me:“Knoxville, Cheyenne 1234 is off Morristown for a clearance to Nashville.” Approach:“Squawk 2345.” Me:“O.K., squawking 2345.” [A bit of a pause.] Approach:“Cheyenne 1234, squawk Oscar November.” I fixed the problem right away.
