While the first and third call districts were unaffected, the FCC
apparently jumped from issuing call signs in the KC2Nxx sequence to
the WQ2Axx sequence, Jahnke said. It also had assigned WQ4xxx, WQ5xxx,
WQ7xxx and WQ9xxx call signs. In the eighth district, there was a gap
between KD8xxx to KM8xxx call signs, while in the tenth district the
Commission went from KC0Txx to WI0Axx. In the sixth district, the
sequence shifted from KG6Wxx to KI6Axx.


Jahnke says the problem appears to have affected only Group D call
signs. He emphasized that any call signs the FCC issued are in the ULS
database and therefore are valid, and licensees may use them on the
air.

"Just don't get too familiar with them," he advised. "It is our
understanding that at some point, the FCC will set aside the
out-of-sequence grants and issue new call signs to affected
licensees."

Unless the calls spell dirty words or otherwise patterns
not avaliable to hams, why not just let them stand? If
you could apply for it as a vanity call, just let whoever
got it keep it.
