Two reasons.  The main one is that the local AM station's signal doesn't
depend on propagation.  It is always there, day or night, with no
fading.  The other reason is that the relatively low frequency is less
affected by the K3 calibration.  For calibrating the P3 that gives a
slight advantage. 

But WWV works fine also.
