I second that. Very informative and I haven't seen this information collated anywhere else. Definitely one to save. CW by ear scores better than I would have guessed. Being a Morse code enthusiast I'm happy to see that. CRC and synchronising bits shouldn't be counted as payload information so some of the table entries need higher Eb/N0. The table shows the cost you have to pay (in Eb/N0 terms) to make a digital mode robust with respect to drift, fading, interference, and have ease of use and a limited bandwidth. -- Paul Nicholson http://abelian.org/ --
