AUX operations may appear as applications, but these won't appear in  
the CDBS. Obviously, the AUX operations will appear on licenses.

The two most recent which come immediately to mind are WCBS/WFAN and  
WWL.

In the WCBS/WFAN case, the AUXes were essentially ratcheted, because  
the shorter than Class A radiator gave high-angle radiation to co-and  
adjacent-channel stations.

In the WWL case, the AUX was granted at 5 kW, 10 kW LS, for the same  
reason, except in this case the co-channels were recently granted  
Class As in Central and South America. WWL did not seek a DA for its  
AUX, although it owned the directional Class B into which its AUX  
site was installed, apparently because the taller of the two towers  
was on the north side of the array, not the south side, as one would  
usually expect from an unequal height array.

WLS' AUX was built before "Rio", and hence before there were loads of  
low-power and super-power Class As to deal with during the  
applications process. Its 199' AUX is painted. but not lighted, and  
unlike post-"Rio" AUXes, it is capable of, and is licensed for a full  
50 kW.

Similarly, KFI and KNX have AUXes.

KFI's is very short, and is only capable of 25 kW. A temporary AUX  
was reportedly used at an otherwise abandoned site during the  
attempted erection of the first 2008 tower (failed catastrophically  
at 300', due to a support structure failure) and also during the  
erection of the second 2008 tower, a duplicate of the first 2008  
tower, but with dramatically improved support structures.

KNX has a 135 degree AUX, presumably capable of a full 50 kW. This  
tower was originally on the wrong side of the 195 degree MAIN tower,  
leading to the technical failure of the decades-ago DA-D experiment.  
After the site was donated for a park, the AUX tower was apparently  
moved to the right side of the main tower, but the DA-D has not been  
attempted again, although the positioning of the towers is now  
correct for a DA-D.

KNBR has an AUX, and it is one of the two supporting towers  
originally employed for then KPO's horizontal, which was the  
station's pre-1949 MAIN operation. KNBR originally was limited to 5  
kW for its AUX, not because of anything besides the limited capacity  
of its emergency generator and its 5 kW AUX transmitter.
