There are a total of 26 letters in the alphabet.
If the call letters must start with either a K or a W, that leaves 24 possible letters for the remaining 3 positions.
Since the letters can be repeated, there are 24 options for each of the 3 remaining positions.
Therefore, the total number of possibilities is 24 x 24 x 24 = 13,824.
Therefore, there are 13,824 possible combinations for a radio station's call letters with 4 letters that can be repeated.
