Oh and the fact that the machines themselves send the messages via special radios also provides an additional level of encryption, since every key push / character is converted to an entirely different key push by the machine and then translated by the radio into a number of electric pulses, which then becomes a number of radio-wave pings in the actual message. The receiving radio converts the radio wave pings back into electrical pulses and the pulses are sent down a certain wire depending on their length.

In other words, intercepted messages come out into a number depending on how many pulses comprise each letter, with each number of pulses being distrinct to a given character / key. If you don't know the configurations of the keys, what letter corrisponds to what number of pulses (which has nothing to do with the regular English alphabet or a normal U.S. keyboard), you won't be able to figure any of it out anyway.
