Hi, quick question on Fractionated Morse does it always end in X or XX or does it vary?

Same principle. You know T(19) -> M(12)and H(7) -> W (22)

So (19a + b) mod 26 = 12
and (7a + b) mod 26 = 22

Subtract to get

12a mod 26 = (-10) = 16 [-10 is 16 because we're doing arithmetic in mod 26]

Now hunt for a solution
12a = 16 is no good (16/12 has remainder 4)
12a = 42 is no good (42 ...
