Thanks. I have 30 examples I got from the API, many moons ago https://github.com/moreati/chirppy/blob/master/examples.json. My finite field knowledge is not up to solving it analytically, my attempts to brute force it are in https://github.com/moreati/chirppy/blob/master/trials.py. That includes functions to go between the characters, and integer representations.
