There are many US airports that don't have the "K".
Examples include:
2B2...Plum Island (Newburyport MA)
7B9...Ellington CT
0B5...Turners Falls MA
and...
B18...Alton Bay Ice
Why no "K"?
If there is no weather broadcast via a radio frequency from the airport there is no K.
K?
This is but a piece of the ICAO airport identifier protocol. I believe that weather reporting is required (among other things) to conform to ICAO. The K means it conforms and thus has the weather reporting.
I reserve the right to be wrong though...
