I earned my Signaler Badge when I was in Boy Scouts way back in the early '70's.

That badge was dropped around 1990 something but revived for the Hundred year anniversary.

Requirements

To obtain a Merit Badge for Signaling, a Scout must:

1. Make an electric buzzer outfit, wireless, blinker, or other signaling device.
2. Send and receive in the International Morse Code, by buzzer or other sound device, a complete message of not less than 35 words, at a rate of not less than 35 letters per minute.
3. Demonstrate an ability to send and receive a message in the International Morse Code by wigwag and by blinker or other light signaling device at the rate of not less than 20 letters per minute.
4. Send and receive by Semaphore Code at the rate of not less than 30 letters per minute.
5. Know the proper application of the International Morse and Semaphore Codes; when, where, and how they can be used to best advantage.
6. Discuss briefly various other codes and methods of signaling which are in common use.

I went on to the 'Order of The Arrow' shortly after that.
