Articles about PSK31

There are several articles that have been published in several magazines or conferences. I am trying to republish here them if the authors and their publishers agree. They can be written in any language. If you have prepared some material and would like to have if published, please send it to me in Word 7 format and I'll try to convert it to PDF format.
