It could be either or a combination of both that is overloading the BA's AM 
front end. I haven't bothered to figure this out because it really doesn't 
matter -- what matters is that the BA's front end should not be saturating 
four miles from these stations.

The saturation only happens when I connect the BA's external AM antenna, 
BTW. But I found that the internal antenna didn't have enough gain to get 
*any* HD reception. As it is, the BA will lock onto KCBS's HD signal if I 
rotate the external loop correctly. But it doesn't even receive 910 or 960 
in analog (they are wiped out by the overload), let alone in digital.
