Hello everyone!

I posted the image below as available after a fellow on the “boatanchors” listserver asked for a copy of it.

It’s from my 1957 copy of the League’s Learning The Radiotelegraph Code.

The League got it from earlier Signal Corps publications.

It shows the “right” way to form block capitals for speed and clarity when copying code.

Remember, military nets generally went at about 15 wpm since copy conditions were so variable, and so much of what was sent was cipher groups rather than “plain text.” Plus, other personnel had to be able to read the copy.

If you’re going to have any CW operation on any Field Day or other event you’ll be publicizing, a “blow-up” of this chart, a little text of explanation, and you’ll have an interesting, informative display piece.
