Some of the frequencies are out of order, and there are no entries for CI and CK. Also note that there are two frequencies each for AD and AE. While it's interesting to note that several of the frequencies listed are (or have been) active numbers frequencies (or home to other strange stations), it would be very easy to fabricate such a list. Number stations tend to use a few bands of frequencies; any frequencies in these bands are likely to be used at some point by one or more number stations.
