Decoder
To decode a message, select the code from the menu, enter the coded message in the box, and then click the Send button.
Note that the Thunderbirds code uses a non-standard character, a square, to encode the number 9. Should the message you want to decode include instances of the square, please replace it with a # (hash).
The Gerry Anderson Complete Comic History would like to dedicate this Decoder to the memory of Ivan Quant, and thank those agents who sent codes to Thunderbirds the Comic.
