Numbers stations
Numbers stations are shortwave radio stations of uncertain origin. They generally broadcast people reading streams of numbers, words, or letters. Evidence supports popular assumptions that the broadcasts are channels of communication used to send messages to spies. So, in that tradition…. here are some numbers: 03B1 03C0 03BF 03C3 03C4 03B1 03C3 03AF 03B1
First one to work it all out gets bonus points….
