25. Some more numbers on WPX CW 2010 41 CW-Skimmers in 21 Countries DX-Cluster RBN Total Spots ~39700 ~837900 Callsigns 8240 21300 WPX Multis 2118 2942

26. So what? Is it…. Good or Bad?

27. So what? Is it…. Good or Bad? It is different! New information handling strategies needed!

28. Information Fusion Algorithm

29. Algorithm Example Check Master.dta No Yes Check QRZ.com Yes No Trash Spot Sent to WinTest

32. The SDR concept Signal Processing User Interface RF Independency of components!

33. Example: Softrock Receiver & PC QSD (e.g. Softrock) IQ (stereo) 0…96kHz signal PC with Soundcard & SDR Software (eg Winrad)

34. Example: Softrock Receiver & PC Signal Processing User Interface RF Operator PC with Soundcard & SDR Software QSD (e.g. Softrock)

35. Why haven‘t SDRs taken off yet? Advantages Great RF performance Great experimentation plattform Very flexible Inexpensive But… PC needed

36. How future solutions will look like Headphone DSP & Interface RF Part (SDR) Control Data Processing

38. Personalized User InterfaceData Processing

42. Backup Slides

43. Example #2 Dutch WebSDR PC with Browser WebSDR Server Direct Sampling Receiver with Direct Down Converters PC with Browser Internet IQ Signals (Ethernet) 7 Bands simultaneously PC with Browser

44. Example #2 Dutch WebSDR User Interface PC with Browser Operator User Interface Signal Processing RF Operator PC with Browser Internet WebSDR Server Direct Sampling Receiver User Interface PC with Browser Operator
