@oh8hub No FEC, though I'm thinking of adding it. I mainly designed the protocol for VHF use, so I think it would be less useful since VHF is a lot more of an all-or-nothing frequency. (There's a pretty narrow window where some bits flip, but not a lot)
I'm not sure how much of a difference it would make to use difference types of compression, but I've been considering sending the data non-compressed if it's better(already-compressed files results in sending slightly more data otherwise)
