Modem design is a science with something like 70 years of history. The modem technology is probably a discussion hashed out on places full of DSP / modem gurus like the GNURadio lists, rather than a list full of activists. There are many complex technical considerations that depend on the properties of the underlying radio transport. Figuring out what kinds of hardware and channels (bandwidth, noise characteristics) are potentially available would be a good thing for activists to get sorted out before going to the DSP gurus and saying "we want to support (one/two way) digital comms at this bitrate over this hardware / spectrum / under these conditions, what should we use here"? -- Too many emails?
