decoding US Civil War telegrams

decoding US Civil War telegrams

RE: decoding US Civil War telegrams

Ah, codes and ciphers. Endless fun for people with debilitating pattern-recognition skills.
The "Maker" people are getting into home-made ENIGMA machines.

One of my favourite ciphers is a sweeping spectrum of repeating radio pulses, which looks nearly random until the right decoding technique can be used.
To decode it, you need to do a a Fourier analysis using the right time domain, then plot each solution beside the last until it makes a long strip.
The sequence of pulses will appear like pixels of a dot-matrix pattern, which spells out the letters of the message.
