The Morse encoding uses a total of 382 base-3 numbers to represent 129 characters (including the spaces). The weight in bits is then 382 x log23 =
605.4, or 4.69 bits/character. Besides being more practical than a base-27 encoding, Morse Code is cheaper in bits per character. This is because
Morse Code takes advantage of the differences in relative frequency of characters in an English text

weve got 0,1,2,3 if zeros are place markers, we get base three encoding.
