Don't tune out. Translation follows.

Translation:

R TNX FER QSO DE NEIL SK

Further translation: I acknowledge receipt of your message thanks for the conversation from Neil End

And thanks to all here for tolerating my silliness.

For those who want a little more information about the genius of Samual Morse, he developed his code so the most frequently used letters had the shortest code time.

For example, DIT = E, DIT DIT = I.

The least used letters used the longest code: Z = DAH DAH DIT DIT, Q = DAH DAH DIT DAH.

You might have noticed that I sent FER insted of FOR. We do this because the code for FER is shorter than that for FOR. We also use DE instead of FROM or THIS IS since it is shorter.

There is a mathematical measure for coding efficiency called coding entropy. Morse's code has a very low entropy, meaning it is highly efficient. The ASCII code used to represent characters for character storage on computers and over networks has a comparatively high entropy (low efficiency).

So, in an effort to et back on topic for this board, I suggest that it would be neat if part 15 stations identified in Morse Code. Twenty words per minute sounds almost like music.

Hope you had as much fun as I did with this post.

Neil
