AMPRnet, net 44, is allocated to ham radio IP networking. There's a wiki and discussion list that might be a good start.On Sun, Feb 25, 2018 at 12:33 PM, Robert <robert.withers@xxxxxxxxxxxxxx> wrote:I am thinking about how a protocol could be written to talk over ham radios and am unfamiliar with transmissions supporting a network. I am working on ReedSolomon encoding to provide forward error correction to transmissions.

There is a small group of IETF hams, but it isn't very active. You might also want to check out AX.25 - a data link layer used by the Amateur Radio community, and FX.25, which adds forward error correction. https://en.wikipedia.org/wiki/FX.25_Forward_Error_Correction Another good reference: http://www.tapr.org/pr_links.html Miles Fidelman -- In theory, there is no difference between theory and practice. In practice, there is. .... Yogi Berra |
