Thinking about writing a small
sound-card application to implement CPM.
In theory it should significantly outperform
PSK31 if I manage to implement it correctly!
Thinking of doing something based on
LRC H=2, M=2, L=3. Will make a good
training exercise either way.
Still working on the PCB.....
Reading about the performance of CPM
in a fading channel. So far it has only been
analysed in a Gaussian channel in the book.
Reminisced a bit about my short time at the BBC
