Modulation is 8-FSK at 2.857 baud. FEC uses convolutional codes with K=14, r=1/4, K=15, r=1/6, or K=16, r=1/8, depending on message length. Synchronization uses 8�8 Costas arrays at the beginning and end of a transmission, followed by two additional symbols to distinguish between 30-bit, 48-bit, and 78-bit messages. Total bandwidth is 23 Hz. At present, only the 78-bit messages have been implemented.
