Our project is to make a Morse code relay system, where we have one Sender node, which audibly broadcasts it's datagram with Morse code encoded message or control at Frequency A. Some Relay node (or multiple Relay nodes) will detect the Morse code and rebroadcast at a different frequency, B. Destination node detects Morse Code and takes action based on the input.
