Does anyone know what of Pactor I/II/III is covered by patents versus what is proprietary information, or trade secrets? With patents there is at least supposed to be full disclosure of how the thing works; and patents have a limited lifetime.
Then we have talked about STANAG-xxx and MIL-STD-xxx and presumably those protocols are published and are open for implementation. Whether they are appropriate for amateur radio is a different question. Then you can look at web pages for vendors like Rockwell-Collins and see that they are offering e-mail between airplanes and ground stations, and that sort of thing. Are they using the published protocols or something proprietary? One reason for adopting STANAG-xxx is to permit interoperation with non-amateur services, should that become necessary. Another reason is that those schemes are developed for agencies who can pay big bucks for the best that can be achieved, so they are likely to be technically superior to things independently invented. Although amateur radio may involve a niche - maybe we want a technically superior way to do what the agencies using STANAG-xxx don't want to do. Need a Digital mode QSO?
