From the developer:
AirPort Utility 5.6.1 for Mavericks resolves a problem as old as OS X 10.9 itself: a system file upon which AirPort Utility relies was updated in 10.9 and that update broke backwards compatibility with AirPort Utility v5.6.1. The file in question is Apple80211 in /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A.
