Call letters in the form KA4993 are mobile-only licenses issued
up until a couple of years ago, presumably when they ran out of
numbers.  For example, our fire department has three sets of call
letters:
	KGE609 -- Base station only at station #1
	KIT823 -- Base station only at station #2
	KC7766 -- All mobiles and portables at both stations.

This was required because the licensee name is the same on all
licenses.  Mobile-only licenses issued recently have five digits instead
of four, and I can't remember offhand whether there are two, three,
or four letters in front.  Recent Base-only and Base-Mobile licenses
are of the form KNxx000 -- four letters beginning with KN, followed by
three digits.
