7a155a4820 Refactor compound call structure for directed messaging by using a new frame type FrameCompoundDirected. This allows us to send only two frames when each station has a compound callsign. No aliasing, full calls are sent with each transmission. 2018-08-05 11:42:02 -04:00

b8267372e4 Added varicode encoding of messages
What this does is allow us to pack more than 13 characters in a single
transmission frame. Optimized using a Huffman encoding using weights of
alphabetical frequency, this will often allow us to send less than 5 bits
per character.
