lecture from Nico Palermo, the developer of Perseus SDR. There will be= also a presentation

of new digital modes designed by K1JT and Klaus DJ5HG on the theoretic= al and practical

limits of digital QSOs

http://www.eme2016.org/index.php/25-2/

But as you all know for good, this is not ONLY an EME territory ;-)

Have found a paper were Nico explains a lot about QRA codes.

http://microtelecom.it/qracodes/= QRACodes-Rev10.pdf

Unfortunately I'm not able to un= derstand even a minimal portion of the story

May be Paul Nicholson can explain us = a bit and how it relates to Eb= Naut, if any !
