Encode text as INMARSAT-C WAV signals and decode it back.
This Python CLI converts IA5 or ITA2 text into 600 or 1200 bps INMARSAT-C baseband WAV audio, then reverses the process to recover the message. The codec includes convolutional FEC, block interleaving, FSK modulation, frame synchronization, and CRC checking. It is suited to protocol study and codec testing and requires Python 3.7+ with NumPy.
