The paper is apparently not finished. I found it interesting that he implies that there is a systematic effort going on to catch "intruders", aka pirates.

Hallo - recently I published a paper on general monitoring:
www.ratzer.at
(right column, "A-DX Download": Intruder Watch: Monitoring - DK8OK)
It takes so-called "intruder watch" as example and shows how to spot
broadcasting as well as utility station in a 24 h hours sonagram, 200 kHz
wide (software: SDR-RADIO.COM).
The technique is shown with 20 screenshots, and it can be applied also to
other bands and users.
Core idea of the paper is to show how powerful a sonagram works digging out
signals of only short duration by just amateur means.
Critics and suggestions welcomed.
